One of the difficulties that I faced when I joined Cognitive Neurorobotics lab was that I wasn’t familiar with the terms used in the lab. Some terms are from the field of dynamics and some other terms were “coined” by my advisor (Prof. Tani). So, it took me quite a time to understand them. I guess it might be a bit more difficult for other people sometimes.

So, I’d like to briefly explain those terms that can be frequently found in my studies on “cognitive neurorobotics” or in Tani’s book (“Exploring Robotic Minds Actions, Symbols, and Consciousness as Self-Organizing Dynamic Phenomena”). This post is targeted to the general audiences (someone like me five years ago). So those terms won’t be explained in a great detail. Instead, I’ll just try to give a general idea about them.

When I train my neural network models, I often use the method called “Softmax Transformation”. It is the method of representing the training data into the sparse form. When I first learned how to do it, I had some troubles ‘cause there wasn’t enough example about how to do it. And still, I can’t find nice explanation about the softmax transformation with examples. So here I have some brief explanation and sample codes for the softmax transformation. Let’s see how the softmax transformation works step by step.

Last September, I attended the ICDL-EPIROB 2017 which was held in Lisbon, Portugal. I really enjoyed the conference and the beautiful city and I also had a great time with my old & new friends :)

This time, I was lucky to have an opportunity for the oral presentation. I had my presentation on my recent study on visuomotor learning, particularly on P-VMDNN (Predictive Visuo-Motor Deep Dynamic Neural Network).

The manuscript, the presentation slides (pdf) and the supplementary videos that I used during my talk can be downloaded from below:
