Theano Tensors Explained in a Picture

Lately I've been doing some experiences with Theano and Deep Learning. One thing that I really thought could help is to understand the workflow of a Theano algorithm through visualization of tensors' connections. After developing the model, I printed the prediction algorithm for a deep learning Neural Net with 2 hidden layers, 2 inputs X1 and X2, and a continuous output Y. I used Graphviz and pydot to generate the graphic with this line of…

Static & DYNAMICAL Machine Learning – What is the Difference?

 

In an earlier blog, “Need for DYNAMICAL Machine Learning: Bayesian exact recursive estimation”, I introduced the need for Dynamical ML as we now enter the “Walk” stage of “Crawl-Walk-Run” evolution of machine learning. First, I defined Static ML as follows: Given a set of inputs and outputs, find a static map between the two…

What are the greatest inefficiencies data scientists face today?

This article was written by Claudia Perlich. Claudia is a Chief Scientist Distillery and Adjunct Professor at NYU. She is also a Data Scientist at Quora. 

First of, let me state what I think is NOT the the problem: the fact that data scientists spend 80% of their time with data preparation.…

Case Study: How a global gaming company used data analytics to beat the odds

It may be in the entertainment domain but Wargaming’s data analytics operations are as humongous as that of any Fortune 500 company. Wargaming is a leader in the free-to-play Massively Multiplayer Online (MMO) game market across all gaming platforms – PC, console and mobile.

 

Just to get a grasp of the enormity of…

Context Levels in Data Science Solutioning in real-world

A Data science-based solution needs to address problems at multiple levels. While it addresses a business problem, computationally it is comprised of a pipeline of algorithm which, in turn, operates on relevant data presented in proper format. Thus to understand the them we need to focus at least at the

  • Business level;
  • Algorithm level; and
  • Data level.

Contrary to the popular belief, almost all non-trivial data science solutions are needed to be…

Human Brain vs Machine Learning - A Lost Battle?

Human (or any other animal for that matter) brain computational power is limited by two basic evolution requirements : survival and procreation. Our "hardware" (physiology) and "software" (hard-coded nature psychology) only had to evolve to allow us to perform a set of basic actions - identify Friend or Foe, obtain food, find our place in the social tribe hierarchy, ultimately find a mate and multiply. Anything beyond this point, or not directly leading to this point can be…

R vs Python? No! R and Python (and something else)

WOLFRAM MATHEMATICA

Before assessing R and Python, I will start with Wolfram Mathematica. It's a powerful software, similar to MatLab. You can handle lists and matrices easily, you have all the best mathematical functions, backup of Wolfram Alpha and extremely sophisticated graphics visualizations, that allow you, for instance, to make and visualize an animated gradient descent, animate different weights for a given neural network, choose a specific…

Make It So, Number One

I found some leftover hamburgers in the fridge. I decided to stack a couple of them together to form a colossal “super-burger.” At the time, I didn’t appreciate how doing so would make it almost impossible to physically fit the burger in my mouth. I squished and squeezed the burger until it was flat enough to eat. Such are the problems of physics that become…

Scraping with 300 req/sec in R? Yes you can!

Try the new non-blocking http API in curl 2.1:

R sitemap example, Jeroen Ooms, 2016

This code demonstrates the new multi-request features in curl 2.0. It creates an index of all files on a web server with a given prefix by recursively following hyperlinks that appear in HTML pages.

For each URL, we first perform a HTTP HEAD (via curlopt_nobody) to retrieve the…
