A Tutorial on the Expectation Maximization (EM) Algorithm
During the E-step we are calculating the expected value of cluster assignments. During the M-step we are calculating a new maximum likelihood for our hypothesis. Bio: Elena Sharova is a data scientist, financial risk analyst and software developer. She holds an MSc in Machine Learning and Data Mining from University of Bristol.
Free Must Read Books on Statistics & Mathematics for Data Science
The selection process of data scientists at Google gives higher priority to candidates with strong background in statistics and mathematics. Not just Google, other top companies (Amazon, Airbnb, Uber etc) in the world also prefer candidates with strong fundamentals rather than mere know-how in data science. If you too aspire to work for such top companies in future, it is essential for you to develop a mathematical understanding of data science. Data science is simply the evolved version of statistics and mathematics, combined with programming and business logic. I've met many data scientists who struggle to explain predictive models statistically. More than just deriving accuracy, understanding & interpreting every metric, calculation behind that accuracy is important.
Learning AI if You Suck at Math -- P7 -- The Magic of Natural Language Processing
After discovering the amazing power of convolutional neural networks for image recognition in part five of this series, I decided to dive head first into Natural language Processing or NLP. This hotbed of machine learning research teaches computers to understand how people talk. When you ask Siri or the Google Assistant a question, it's NLP that drives the conversation. Of course, as an author of novels and articles, working with language seemed like the obvious next step for me. I may suck at math but words are my domain! So I set out to uncover what insights NLP could give me about my own area of mastery. I had so many questions. Had NLP uncovered the hidden keys to writing heart-wrenching poems? Could AIs turn phrases better than the Bard? Luckily, I had just the right project in mind to test the limits of NLP. I was in the midst of naming the second book in my epic sci-fi saga The Jasmine Wars but I'd struggled to find the perfect title. What if I could feed a neural net with the greatest titles of all time and have it deliver a title for the ages? This isn't my first foray into computer assisted title generation. There are a number of random title generators out on the interwebs that I've tried from time to time. They're the type of toy you play with for a few minutes and then move on.
Gradient Boosting – the coolest kid on the machine learning block
Gradient boosting is a technique attracting attention for its prediction speed and accuracy, especially with large and complex data. Don't just take my word for it, the chart below shows the rapid growth of Google searches for xgboost (the most popular gradient boosting R package). From data science competitions to machine learning solutions for business, gradient boosting has produced best-in-class results. In this blog post I describe what it is and how to use it. Machine learning models can be fitted to data individually, or combined in an ensemble.
100 Free Tutorials for learning R
R language is the world's most widely used programming language for statistical analysis, predictive modeling and data science. It's popularity is claimed in many recent surveys and studies. R programming language is getting powerful day by day as number of supported packages grows. Some of big IT companies such as Microsoft and IBM have also started developing packages on R and offering enterprise version of R. What is R? R is a free language and environment for statistical computing and graphics. You can perform a variety of tasks using R language.
Adiabatic Quantum Computing for Binary Clustering
Bauckhage, Christian, Brito, Eduardo, Cvejoski, Kostadin, Ojeda, Cesar, Sifa, Rafet, Wrobel, Stefan
Quantum computing promises fast solutions to a wide range of optimization problems and thus holds considerable potential for machine learning [1]-[3]. However, while the quantum machine learning literature so far mainly focused on the quantum gate paradigm, noticeable technological progress leading to commercial devices is happening in adiabatic quantum computing [4], [5]. Current adiabatic quantum computers are geared towards solving quadratic unconstrained binary optimization problems or Ising models. A simple strategy for setting up established learning algorithms to run on such devices is therefore to attempt to (re-)formulate or approximate their minimization or maximization objectives in terms of Ising models. In this paper, we apply this strategy to a simple unsupervised learning problem, namely binary clustering.
Duolingo introduces chatbots to help iPhone users learn a foreign language
There are many ways to try to learn a new language, ranging from audio books and text books, to software and web-based options. One learning tool that's proving popular at the moment is Duolingo, and a new feature has been introduced that helps to provide an immersive linguistic experience. It is said that one of the best ways to learn a language is to visit the country that speaks it and surround yourself with native speakers. As this is not always possible, Duolingo's new chatbot feature could be the next best thing. The chatbots are currently only available to iPhone users, but it gives language students the opportunity to try something that may not otherwise be available to them -- to try out their language skills on a native speaker.
Are Left-Handed People More Gifted?
The belief that there is a link between talent and left-handedness has a long history. Leonardo da Vinci was left-handed. So were Mark Twain, Mozart, Marie Curie, Nicola Tesla and Aristotle. It's no different today – former US president Barack Obama is a left-hander, as is business leader Bill Gates and footballer Lionel Messi. But is it really true that left-handers are more likely to be geniuses?
