Machine Learning Crash Course From Google

We’ve talked a lot about machine learning lately. People use it to create and recognize speech, computer vision and even radio signals. If you still need to make progress on the learning curve, you might be interested in a new free Google course with TensorFlow.

Of course, we’ve already covered tutorials for TensorFlow, but this is structured as a 15-hour class with 25 hours and 40 exercises. Of course, it’s also out of the horse’s mouth, so to speak. Google says the class will answer questions like:

  1. How does machine learning differ from traditional programming?
  2. What is a loss, and how do I measure it?
  3. How does gradient descent work?
  4. How do I determine whether my model is effective?
  5. How do I represent my data so that a program can learn from it?
  6. How do I build a deep neural network?

Google says that you have to be an expert in introductory algebra and that higher math can be helpful, but not essential. You should also know something about programming with some familiarity with Python. The exercises are executed in your browser, so you do not need exotic settings. There are also some tools that suggest tutorials if you do not know them anymore. For example, the pandas and bash library are included in this list.

If you’re really serious, Google has lots of educational resources to keep you going. If you learn by a better example, you can try to undress.

History Of Crowdfunding [Infographic]

Crowdfunding may seem like a new idea, but it actually has a long and rich history with roots going back to the 1700’s.

However, modern-day crowdfunding — where people and businesses raise small amounts of money from a large group of people, usually online — has its origins in 1997.

In this infographic, we look at some of the historical movements that led to the development of crowdfunding as we know it, as well as major events over the past two decades that have shaped modern-day crowdfunding.

“AI” Of Human-Kind

“AI”… of Human-kind!

“Which Came First, The Chicken Or The Egg?”

Several years ago, you may recall a publication describing our growing dependency upon machines, devices, and “AI.” On several occasions, I’ve attempted to bring awareness to this phenomenon of artificial intelligence’s abilities in creating and/or re-creating itself… over and over again. What once was a ‘science-fiction’ story has been brought to bear, in living color, a scientific fact.

The article, “Device Machine Dependent,” has described instances and descriptions where robots or robotics have been designed to emulate the actions, abilities, and appearance(s) of mankind… “Human-Like”; “The Image of Its’ Creator!”

How many times have you been in your car and engaged in a shouting match or argumentative interaction with your ‘GPS’ or “onboard interface?” Aw, c’mon now… haven’t you gotten angry and screamed at the device when the voice behind it gives you screwed up or wrong directions? Sure you have.

Selene Yeager, a contributing author, spoke of a doctoral student at Stanford University, who specializes in Human-Technology-Interaction.

“We (humans) get confused and angry because we don’t know what the ‘GPS’ is “thinking,” David Miller says.

This author (yours truly), however, is and has been guilty of that particular type of behavior. I can remember keying in a direction (when that wasn’t satisfactory, I tried to engage the voice command option), the damned thing told me; directed me to take a highway and exit… I followed suit. When I realized the directions where totally wrong – the accursed voice put us on “The Highway To Hell!”

We traveled sixty miles outside and away from our planned “Pocono Mountain” destination.

Well, I’m here to tell you, I momentarily (Oh, like so many) became insane and started screaming at the voice inside of the ‘GPS system.’ Miller went on to say, “In the future, when your GPS gives you directions, it may give you a rationale, so that you will have a better two-way relationship.”

… Yeah, right. I’m happy when and if the thing gets me to my unfamiliar destination(s)… via the correct route! I don’t mean to be too hard on the device… it’s a pretty good little tool when it works as expected.

“A Bite Of The Apple” addressed the ‘IT’ community on big issues concerning Apple’s stance on “covert and proprietary practices” in the world of technology; hardware and software – particularly its hardware products. Apple’s ‘IT’ decision makers espouse an ergonomic flaw which reveals a preference, They’ve said “Apple-like” form over function, i.e., the iMac connectors on the rear of their machines are designed and/or decided by anal retention.

Their ‘IT’ management team describes one possible meaning of “Anal Retention.” It’s a point on a curve at which the curvature changes from convex to concave or vice-versa. It can also be called a “Flex Point” or “Point of Inflection.” Apple management says its proprietary devices are putting more effect into business user marketing. Apples’ devices are making their way into the enterprise arena because ‘IT’ managers, not users, like them.

The ‘end-user’ report stresses the fact, suggesting the product(s) being as good and excellent on ease of use, design, and reliability. Does anyone recall the definition of cloning?

Many of us have PC’s in our homes today. And there are many others who feel they are, and believe they are a step ahead while utilizing home-robots like “Alexa” or IBM’S “Watson” and a myriad of cloned devices that clean, monitor, and coordinate their daily lives or lifestyles.

Where’s your cell phone?

It used to be the desktop computer that was the central ‘Internet’ connection. Then it was the ‘Laptop.’ The “Tablet” continues to be popular these days, but the “Smart-Phone” outshines them all. All one has to do is simply look around… Look and see how many people are walking, running, riding, driving, and flying… dependent upon those continually unrelinquishing devices to sustain them in their existence, and their very lives on this planet.

Not long ago, a vicious computer virus wrestled control from some 400,00 computers across more than 160 countries in one of the worst international cyber attacks and computer infections.

The virus blocked all access to programs, files, mainframes, and networks unless the computer’s owner(s) paid a ransom. The eligible funds could only be paid via “Bitcoin.”

Bitcoin is the online currency that is almost impossible to trace. The Bitcoin currency is traded for the purchase of a “ransom key.” Often, victims have paid the money only to not get the key to unlocking their computers (or) systems, losing both their money and their data.

This incident should serve as a major wake-up call to users with the much encouraged “must-do” procedure(s) on PCs and Internet devices in their care or usage and the prevention of viruses, botnets, web-crawlers, malware, worms, etc.

I certainly agree with author, Doug Shadel, in suggesting that users/owners regularly backup your important files to an external drive or remote storage service; have a pop-up blocker running on your web browser at all times; instantly leave websites you’ve been routed to without your consent; use a reputable antivirus program – keeping it updated at all times; make sure your software (and anti-virus software) is up to date; don’t click on links or open attachments from email addresses you don’t know; and buy only legitimate software – and register it.

Do you remember the scene in the movie “Star Wars,” where the bar-tender shouts at ‘Luke Skywalker’ to get his droids out of his establishment?

That scene is a result of human prejudices against machines or robot-kind. Detroit, Michigan’s automobile industry, and the workforce is all but totally manned by robots (or robotics). Robots are doing major operations on humans and animals alike. Robots are preparing foods, packing and shipping items, driving cars, and diagnosing human ailments and diseases. Robots are answering telephones and redirecting calls. Robots are calling you on your telephones, reminding you of past due bills, appointments, prescription pick-ups, and making attempts at selling you goods and other services. Robots are building bridges, buildings, and homes. Robots are doing just about anything and everything a human-being or animal can and has been doing. Ask yourself… how many jobs have been lost and are being lost to robots?

“Many companies are using sentiment analysis to gauge the mood(s) on social networks and/or the web… but getting insight takes new tactics and skills,”

“It definitely takes new tactics and skill-sets in order to acquire a position in the new world of IT, BI, Communications, and Analytics.” This conclusion is postulated via the published article, “Destruction and Creation – A New Jobs Hyperbole.” No one can deny the massive and major changes that have occurred in the ‘New World Economy’ of this century. What’s going to happen in the centuries to come – will we be “Star-Trek-Like?” How about a world and future like that of “Logan’s Run?” Will robots become the new judges, lawyers, congressional appointees, senators, or president? Those of us who are aware, interested, and/or motivated in or toward the continuation of mankind’s reign over machines, must become the master of both sides of IT/BI.

AI: Artificial Intelligence… is in contrast to the natural (Human/Animal-like) intelligence… the ability of a computer or robot doing what is normally or commonly done by humans or animals – with intelligence or intelligent abilities… the ability to think.

How long will it be before humans (mankind) are completely out-thought by “AI” – becoming completely and utterly our replacements as opposed to being our once-upon-a-time servants?

“How Long? Not Long!”

Now, doesn’t this argument make you wonder…

“AI”… of Human-kind?

The 9 Biggest Cybersecurity Threats Are Inside Your Company

Your business faces a range of cybersecurity threats. These threats come in different forms, but when someone talks about a security hole, they almost always talk about hackers. These pirates were generally blamed for the attack, but the truth was that they usually came from within. This does not mean that someone in your company actively works with hackers. This is very rare in the case. But many employees make small cybersecurity bugs that open the door for hackers. They do not do what creates a vulnerability that hackers can exploit to enter your system.

Although few companies know that hackers can benefit from something their employees have done, all companies are hacked to watch what happened, to see if something has hired someone or not, and hackers have access to your network. Most of the time they find something. Some of these attacks have been maligned by insiders. Here are some things to think about as you observe their cybersecurity policies and security vulnerabilities.


Read This – Essential 8 Technologies Driving Disruption


Why Insider Threats Are the Most Dangerous

The problem with the threats coming from your own business is that they seem reliable. It is likely that your security system will ignore these threats because they come from legitimate employee accounts that have access to your system. Even if the account does something that may seem foreign to a human being, its automated security systems and network security tools cannot call it unusual.


Mistakes Happen

First of all, remember that mistakes will occur. No matter how strong your security or your policies are, somebody will make a small mistake somewhere that will open the door for hackers. It is not a question of “yes” but of “when”. A laptop with stored passwords will be stolen, someone will accidentally click on a link in an unsolicited e-mail, or someone will send the wrong file to someone else. Even your trained IT professionals can make a small mistake, and since they usually have access to everything, this error can be expensive.

Since mistakes are inevitable, you must have a good emergency plan to deal with an attack. This crisis document should contain as many different scenarios as possible and how the company can respond.

Read This – What is Artificial Intelligence as a Service (AIaaS)?


Malicious Employees Exist

Unfortunately, while accidents happen, people sometimes get angry and decide to do horrible things. Maybe one employee has promoted several times. Maybe someone was offended by something you said. Maybe industrial espionage happens. Regardless of the reason, an employee sometimes decides to intentionally filter information or sabotage their safety. They can do it for money, or they can do it just to get their revenge for an easy drain. Whatever the reason, it is a risk.

By now, you can not assume that every employee will cheat you. You have to have faith in your people. Otherwise, your business might collapse. However, you can ensure that employees can only access the data and systems they need, or you should check the background of the employees at the beginning of the hiring. There are many online tools that allow you to perform background checks on employees to avoid multiple new threats in organizations.


Watch Out for Hijacked Identities

Hackers can also steal the corporate identity of an employee and thus access a system. If a computer scientist sends an email to an employee asking for password information, they will likely return it. You may not even see the email address to which you are sending this information to verify that it is legitimate. Once someone’s identity is stolen, employees can accidentally give the hacker everything they need. Teach your employees to always look for suspicious emails.


Protecting Your Business

What can you do to protect your business from internal attacks? In fact, there are several things you can do to reduce these threats.

Read This – Cloud Service Model – Understand The Types, Characteristics, & Advantages


Remember the Basics

While you may be tempted to look for the latest and most obvious security tools, remember that you should never forget the basics. There are some excellent classic threat intelligence tools that are still very useful today. However, you must always remember to apply patches and updates that have been released. If this is not the case, hackers can exploit some security holes in the software. After full refresh, these tools protect your organization against various new threats.

Also, make sure your employees understand the basics of cybersecurity. You must use strong passwords. You should never connect via public WLAN. You should be aware of existing threats and how to handle them.


Analyze Your System

You can use a detailed analysis to determine if an employee’s account is suspicious. People become habitual: they keep repeating the same things, even if they do not realize it. The analysis allows your automated security systems to detect when something is wrong. Part of it is obvious, such as a co-worker connecting at night. However, some actions may not seem so weird if you have not analyzed the computer usage and user habits of your business.


Know Your Data

Do you know which data is most useful? This is the information hackers want, so make sure you stand behind the strongest firewalls and security procedures. Carrying out an audit and understanding what you consider valuable is an important first step in protecting your data from external and internal threats.


Know Your Employees

In the same way, it is important to know your employees. Know what kind of security risk they represent and what assets they can access. This is much more important when it comes to executives and IT managers, not subscribers and lower level employees. Those who are higher in the business often have much more access to the data. This means that the present is a much greater risk.

Artificial Intelligence system can predict school violence

Scientists have developed an artificial intelligence system that can predict which students are most at risk of school violence. The researchers found that machine learning – the science of learning computers over time without human intervention – is as accurate as a team of child and adolescent psychiatrists, including a forensic psychiatrist, about the risk of violence at school. “Previous violent behavior, impulsivity, academic problems and negative attitudes correlated with the risk for others,” said Drew Barzman, child psychiatrist at the Cincinnati Children’s Hospital Medical Center in the United States. , UU

“Our risk assessments focus on predicting any kind of physical aggression in the school, and we do not collect results data to assess whether machine learning can really help prevent school violence, it’s our next target,” said Barzman. the study published in the journal Psychiatric Quarterly. The researchers evaluated 103 adolescent students at 74 traditional schools in the United States who had greater or lesser changes in their behavior or aggression toward themselves or others. The students were recruited from outpatient psychiatric clinics, inpatient facilities and emergency services. The team carried out risk assessments with the participants at the schools. The sound recordings of the evaluations were manually transcribed and commented on.

It turned out that after two scales developed and validated by the team in previous surveys, students were equally divided between medium to high risk and low risk. There were significant differences in the overall scores between high-risk groups and low-risk groups. The self-learning algorithm developed by the researchers reached an accuracy of 91.02%, which is considered excellent when interview content is used to predict the risk of school violence. The rate rose to 91.45 percent when demographic and socioeconomic data was added.

“The machine learning algorithm, based solely on the participant’s interview, was almost as accurate in assessing the risk levels as a complete evaluation by our research team, including collecting information from the participants.” Parents and school, a review of the records, though they are available and qualify on both scales, “said Yizhao Ni, a computer scientist from Cincinnati. “Our ultimate goal, if supported by research, is to expand the use of machine learning in schools in the future to increase the structures, professional judgment to more effectively prevent school violence,” said Barzman. , ,

Latest Cryptocurrency News – Game Maker Atari Is Planning to Launch Its Own Cryptocurrency

The company, which is behind iconic video games such as Pac-Man and Pong, plans to release its own cryptocurrency, “Game Maker Atari,” as announced last week. (See Also: How is Artificial Intelligence Reshaping eCommerce Sector?)

As part of this effort, Atari acquired a 15% interest in Infinity Networks, Ltd. based in Gibraltar and granted the company a license. The partnership, which was already proposed in a December Declaration, sees the development of a digital entertainment platform supported by Atari’s so-called token. The manufacturer of the game said that his investment was made “without cash payment from Atari”.

“Our goal is to take strategic positions with limited liquidity risk in order to better value investments and the Atari brand,” said Atari President and CEO Frédéric Chesnais in a statement.

The choice of name is remarkable, as Atari had previously created an Atari token to serve as a currency for in-game purchasing. It remains to be seen whether the announced new Atari token will serve this purpose.

In addition, Atari has announced its intention to develop cryptocurrencies through cooperation with Pariplay, Ltd. to integrate online games with Atari games and characters as part of their design. Last week’s statement also clearly highlights the creation of a second token that would be used in conjunction with the online casino plan.

“To increase the appeal of these new casinos, Atari has launched the project to launch Pong Token, a second token dedicated to crypto-casinos that can be used on these gaming sites.” Details on this version of Crypto Casinos will be announced soon, “reads the statement (without translation).

As expected, the announcement did not make very good comparisons for Kodak, the photographer who licensed his mark for the creation of KodakCoin. The project was announced in January, with the intention to make a first currency offer at the end of this month. This token sale was later postponed and since then no release date has been announced.

Bitcoin Price Going Down Day By Day – Here Is The Reason

The joy of Christmas cannot spread to the cryptocurrency markets this year.

The market capitalization of digital currencies hit new highs last week as Altcoins recovered against falling bitcoin prices. But the markets seem to have changed course. Altcoins have joined the original currency by losing their profits as market prices have fallen. Coinbase stops working because of “high traffic”. As long as there is no recovery, it seems that Santa Claus will not visit the cryptocurrency markets.

Images, they say, are more powerful than words. Here’s a price chart for bitcoin’s price at 14:30 UTC.

The cryptocurrency’s price has collapsed by approximately $5,000 (or, 24.73%) from its price 24 hours ago. On a weekly basis, the fall in bitcoin’s prices amounts to 33.24%.

Although a correlation has not yet been determined, the Bitcoin price indicates the price movement for other cryptocurrencies. They mainly move in tandem; Sometimes they get out of reach. Prices for the top 10 best-selling cryptocurrencies have been synced to Bitcoin over the past 24 hours and lost an average of 35% of their price 24 hours ago.

Bitcoin Cash, which released a new record this week, fell 38.91% at the time of writing. Litecoin, Dash, and Cardano were the other cryptocurrencies among the top 10 most traded, with significant value. All three had reached record highs last month.

The general market capitalization of the cryptocurrency market was $ 432.7 billion. On Thursday, it reached a record $ 654 billion.


Will Bitcoin Crash Further?


Given the unpredictability of their movements and the lack of a single correlation factor, this is difficult to say. The technical analysis was unable to accurately predict the price movements of the cryptocurrency. In other words, Bitcoin has recovered the lost ground pretty quickly in the past. For example, it has increased by nearly $ 5,000 to release a new maximum last week.

Takashi Hiroki, chief strategist at Monex Securities, compared Bitcoin trading in gambling as the cryptocurrency does not follow logical patterns. Neil Wilson, the senior market analyst at ETX Capital, told Guardian that the price erosion could be a simple case in which traders are sold by the end of the year to realign their portfolios. An interesting article on Coindesk analyzes the role of credit in Bitcoin price movements. According to author Marc Hochstein, Bitcoin is quickly “funded” and credit is becoming an increasingly important part of its system. He cites a newly created CEO who said he could raise the bitcoin price in the short term, but it would eliminate Bitcoin from a real value stock.

But long-term traders have reasons to be optimistic about bitcoin price movements. It has been the subject of several reports of the institutional money flowing into the cryptocurrency markets. Hedge fund money reaches digital currencies

What Happens When All 21,000,000 Bitcoins Have Been Mined?

Bitcoin is deflationary, which means that the mined currencies are ended. Once the miners have discovered 21 million bitcoins, it will be the total amount of bitcoins that exist. But because of the lost and forgotten portfolios, the number of “active” bitcoins will be much lower and there really is no way to determine the exact number.

Bitcoins can be lost through unrecoverable passwords, forgotten wallets when Bitcoin is worthless, hardware bugs or the death of the owner of bitcoins. It is extremely unlikely and even impossible to recover lost coins. As of March 31, 2015, the total value of lost bitcoins was estimated at approximately $ 1.23 billion. A recent figure at the end of 2016 suggests that up to 25% of circulating bitcoins (just over 4 million) are “dead”, bringing the estimate to about $ 25 billion.

When Will the Last Bitcoin be Mined?

Bitcoin Halving Events.

This is a very important concept to understand when the last bitcoin is extracted. Every four years or so, the number of new bitcoins created and earned by minors with each new transaction block is halved. This is part of the predictable and transparent Bitcoin monetary policy, which can be verified in the source code in the Bitcoin Core GitHub repository.

21 million bitcoins
21 Million Bitcoins Updates


We are currently Reward Number 3 and we have about three more years until the reward payout is halved. As you can see in the table above, there will be a total of 34 “rewards”.

Originally, 50 bitcoins were earned as a reward for mining a block. Then it dropped 25 bitcoins, and then to 12.5 bitcoins. In 2020, it’ll drop to 6.25 bitcoins.

So if we do the math, if there is a halving event every four years, the last Bitcoin should be mined sometime in the year 2140.

What Happens When the Last Bitcoin is Mined?

Is the whole system closed because bitcoins are no longer tuned to extract new blocks? Probably not. Bitcoin Miners also receive transaction fees, and these charges should keep Bitcoin afloat. As the Bitcoin price rises, the rates assigned to each transaction also increase. Take a look at this table, which summarizes Bitcoin’s average transaction rate over time:

21 million bitcoins
21 Million Bitcoins Updates


Finally, these transaction fees should be large enough to encourage minors to continue working even if they do not receive a full reward. As long as the new Bitcoins stop, the Bitcoin miners receive a payment. Of course, some miners are (and are) already forced out of the market.

However, the idea of Bitcoins worth $ 50,000 or $ 100,000 is not unfounded. Currently, at the time of writing this article, the fastest and cheapest transaction fees are currently 150 150 satoshis/byte. For the average transaction size of 226 bytes, this translates into a rate of 33,900 satoshis (about $ 2). Remember that all transaction fees go to the person or persons who operate the block.
