Doing a PhD involves building walls and then demolish them and build them back learning something during the process.

A conceptual machine for cloning a human driver

If anything else, a Machine Learning practitioner has to get a global view and think on how far our conceptual machines can go. This is a little tale of my recent experience with Deep Learning. To start with, say that I am enrolled in the Udacity’s nanodegree inSelf Driving Car Engineer . Here we are learning the techniques needed for building a car controller capable of driving at the human level. The interesting part of the course (to be read as where one truly learns) is in the so called projects: these are nothing but assignments in which the student has to solve a challenging task, mainly by using Convolutional Neural Networks (convnets), the most well-known Deep Learning models. So far, the most mind-blowing task and the focus of this entry is project 3, were we have to record our driving behavior in a car simulator and let a convnet to clone it and successfully generalize the act of driving. It is remarkable that a convnet learns to control the car from raw color images jointly

Data Streams and VFML

-
We live in a technological world crowded of information. Every device we can think of can give us a bunch of such data, usually in the form of a flow or stream of information in, more or less, real time . In this particular situation classical knowledge discovery mechanisms (like our loved C4.5, a decision tree developed by Quinlan) are completely unable of extract a correct model of the situation. But, what is so special with flows of data? Following the words of Gama and Rodriques: a data stream is an ordered sequence of instances that can be read only once or a small number of times using limited computing and storage capabilities. These sources of data are characterized by being open-ended, following at high speed, and generated by non-stationary distributions in dynamic environments . So, to properly handle this kind of knowledge the learning algorithm has to learn on line and process massive amounts of data increasing the challenges to be faced. Let's hold one's breath w

Data Analytics Plus Big Data: A Win-win Strategy

-
We live in a dynamic world where new technologies arise, dominate for a brief blink of an eye and then fall to oblivion rapidly. A part from the academia domain, it is interesting to check what are the current trends in the industry. Or even better: see the whole picture without discriminating. In this regard, a nice analytics tool is found in Google Trends, which allow us to track our terms of interest. The following chart shows the search interest for Machine Learning and Data Analytics . In a similar scale I depicted the search interest for Data Analytics and Big Data . As it is clearly noticeable, knowing both disciplines can open many doors in the industry. Finally, as top and also rising queries, Hadoop is the most popular term.
