Visualizing Algorithms The power of the unaided mind is highly overrated… The real powers come from devising external aids that enhance cognitive abilities. —Donald Norman Algorithms are a fascinating use case for visualization. Machine Learning for Developers by Mike de Waard Most developers these days have heard of machine learning, but when trying to find an 'easy' way into this technique, most people find themselves getting scared off by the abstractness of the concept of Machine Learning and terms as regression, unsupervised learning, Probability Density Function and many other definitions. If one switches to books there are books such as An Introduction to Statistical Learning with Applications in R and Machine Learning for Hackers who use programming language R for their examples. However R is not really a programming language in which one writes programs for everyday use such as is done with for example Java, C#, Scala etc. This is why in this blog machine learning will be introduced using Smile, a machine learning library that can be used both in Java and Scala.

Bayesian Methods for Hackers An intro to Bayesian methods and probabilistic programming from a computation/understanding-first, mathematics-second point of view. Prologue The Bayesian method is the natural approach to inference, yet it is hidden from readers behind chapters of slow, mathematical analysis. The typical text on Bayesian inference involves two to three chapters on probability theory, then enters what Bayesian inference is. Unfortunately, due to mathematical intractability of most Bayesian models, the reader is only shown simple, artificial examples. This can leave the user with a so-what feeling about Bayesian inference.

Top 10 Free Camtasia Studio Alternatives Camtasia Studio is one of my favorite tools. It gives you the ability to create screen recordings, to customize and edit your content, and to integrate it into your eLearning courses. On the other hand, even though it does offer a variety of functions and features, eLearning professionals with tight budgets might find the price tag a bit too steep. The good news is that there are a number of free Camtasia Studio alternatives that can provide any eLearning professional with the opportunity to capture screen images and produce high quality screen recordings. So, it's time to create top-notch tutorials, walkthroughs, and screencast videos with these free Camtasia Studio alternatives. CamStudio This software is great for tutorials.

Why D3.js is So Great for Data Visualization When D3 came out in 2011, it became clear pretty quickly that it was going to be a powerful tool for creating data visualizations. But it’s certainly not the first — or only — tool. Why did it succeed when so many other libraries have failed? First of all, it works on the web. Philosophy of mathematics - Wikipedia The terms philosophy of mathematics and mathematical philosophy are frequently used interchangeably.[1] The latter, however, may be used to refer to several other areas of study. One refers to a project of formalizing a philosophical subject matter, say, aesthetics, ethics, logic, metaphysics, or theology, in a purportedly more exact and rigorous form, as for example the labors of scholastic theologians, or the systematic aims of Leibniz and Spinoza. Another refers to the working philosophy of an individual practitioner or a like-minded community of practicing mathematicians.

Machine Learning at Quora - Engineering at Quora - Quora Adapted from my original answer to How does Quora use machine learning in 2015? At Quora we have been using machine learning approaches for some time. We are constantly coming up with new approaches and making big improvements to the existing ones. It is important to note that all these improvements are first optimized and tested offline by using many different kinds of offline metrics but are always finally tested online through A/B tests.

This Is How to Create Videos in Google Drive July 29, 2014 This week's tip for teachers is about creating videos in Google Drive. As you know, since the time Google made it possible to integrate third party apps into Google Drive, there appeared a wide variety of excellent applications that are deemed to enhance the overall performance of your Drive . One of the essential apps that I think every teacher should connect with Google Drive is called WeVideo. WeVideo allows you to easily create and share videos and short animations.

The most influential data scientists on Twitter Twitter is emerging as an important medium for determining influence in many fields. Social ranking sites like Klout and Traackr include Twitter as a heavily-weighted component of their ranking algorithms, for example. Twitter isn't representative of the members of any field, but in areas where the members primarily engage online, it can be a useful proxy. SocialFlow's Gilad Lotan has used an analysis of social networks on Twitter to rank influences in such fields, including the communities of python users and data scientists. Here's the network chart for data scientists:
