Google's AlphaGo can now teach ITSELF how to win at Go

Daily Mail

In 2015, Google revealed its'god-like' AlphaGo artificial intelligence system - the first computer program to defeat a world champion at the ancient Chinese game of Go. And while it may sound implausible, the incredible system has just got even better. Scientists have unveiled the latest version of the system, called AlphaGo Zero, which learns to play simply by playing games against itself. The researchers hope their creation can help to solve some of the'most important challenges humanity is facing.' The system starts off with a neural network that knows nothing about the game of Go.


How to become savvier with your marketing by implementing artificial intelligence techniques

#artificialintelligence

Gone are the days of guessing what each individual customer wants by researching demographic populations. Take inspiration from some of the largest tech companies like Amazon, Facebook and Google who are investing large amounts of money in machine learning and AI to predict what their customers want before they even know it. Learn how to become a savvier marketer with these suggestions to improve your overall ROI and business performance. By 2018, Gartner predicts that 20% of all business content will be authored by machines. Artificial intelligence will enable content curation by unifying information from diverse datasets, permitting companies to give users more data on usage and other aspects that might interest them from third-party data providers.


Applying some intelligence to Artificial Intelligence

#artificialintelligence

Navigating the turbulent waters of Artificial Intelligence (AI) and Machine Learning (ML) can seem like a daunting task to the uninitiated. In fact even the question of how AI relates to ML is answered differently depending on who you ask, as evidenced by the numerous articles about on these topics. In this area, confusion abounds – for example with ML being linked to predictive analytics, including Monte Carlo Simulations, which have nothing to do with ML! Some of this comes from the breadth of subjects that are related to these concepts. For example Natural Language Processing, Random Forest, Dimensionality Reduction, Neural Nets and Deep Learning do not fit into a nice grouping structure or hierarchy which can defined as just an instance of that overall class of technique. The next layer of complexity comes from the fact that any given use case can actually use a fairly arbitrary combination of these tools to achieve its aims.


Decision Tree Ensembles- Bagging and Boosting – Towards Data Science – Medium

We all use Decision Tree technique on daily basis to plan our life, we just don't give a fancy name to those decision-making process. Businesses use these supervised machine learning techniques like Decision trees to make better decisions and make more profit. Decision trees have been around for a long time and also known to suffer from bias and variance. You will have a large bias with simple trees and a large variance with complex trees. Ensemble methods, which combines several decision trees to produce better predictive performance than utilizing a single decision tree.


Google's AutoML Project Teaches AI To Write Learning Software

#artificialintelligence

White-collar automation has become a common buzzword in debates about the growing power of computers, as software shows potential to take over some work of accountants and lawyers. Artificial-intelligence researchers at Google are trying to automate the tasks of highly paid workers more likely to wear a hoodie than a coat and tie--themselves. In a project called AutoML, Google's researchers have taught machine-learning software to build machine-learning software. In some instances, what it comes up with is more powerful and efficient than the best systems the researchers themselves can design. Google says the system recently scored a record 82 percent at categorizing images by their content.


L1 and L2 Regularization Methods – Towards Data Science – Medium

#artificialintelligence

A regression model that uses L1 regularization technique is called Lasso Regression and model which uses L2 is called Ridge Regression. Ridge regression adds "squared magnitude" of coefficient as penalty term to the loss function. Lasso Regression (Least Absolute Shrinkage and Selection Operator) adds "absolute value of magnitude" of coefficient as penalty term to the loss function. The key difference between these techniques is that Lasso shrinks the less important feature's coefficient to zero thus, removing some feature altogether.


Changing a Lightbulb with a Hammer: Predictive Analytics with Machine Learning

#artificialintelligence

Machine Learning can react, perhaps quickly, but is limited to past observations in development of forecasts. We cannot travel back into the past and generate another set of data so we're limited with to the single historical data set, and we are forced to devise a clever approach to making the most out of badly weakened position. The value is in the ability to quickly compare between multiple approaches and in having the ability to handle large historical data sets. Machine Learning is not limited by assumptions of consistent data generation processes--like traditional forecasting techniques.


Google's Learning Software Learns to Write Learning Software

WIRED

In a project called AutoML, Google's researchers have taught machine-learning software to build machine-learning software. Such results are significant because the expertise needed to build cutting-edge AI systems is in scarce--even at Google. AutoML could make those experts more productive, or help less-skilled engineers build powerful AI systems by themselves. Making it easier to generate and deploy complex AI systems might come with drawbacks.


How machine learning APIs are impacting businesses? by Sandeep Raut, Director, Digital-One, Syntel

#artificialintelligence

A few years back it was the field only for data scientists and statisticians, who used to analyze the data, apply several techniques and provide results. Google Cloud, Microsoft Cognitive Services, Amazon Machine Learning APIs & IBM Watson APIs are the leaders in the market. With growing number of free/reasonably priced APIs and tsunami of data generated every day, the race is on as to which is the best Machine Learning API. These machine learning APIs are not yet perfect or matured and they will take some time to learn and act accurately.


Word Embeddings: An NLP Crash Course

@machinelearnbot

The field of natural language processing (NLP) makes it possible to understand patterns in large amounts of language data, from online reviews to audio recordings. But before a data scientist can really dig into an NLP problem, he or she must lay the groundwork that helps a model make sense of the different units of language it will encounter. Word embeddings are a set of feature engineering techniques widely used in predictive NLP modeling, particularly in deep learning applications. In this piece, I'll explain the reasoning behind word embeddings and demostrate how to use these techniques to create clusters of similar words using data from 500,000 Amazon reviews of food.
