Two Sigma, a leading investment management firm, is impressed with the performance and ease of use of Cloud TPUs. "We made a decision to focus our deep learning research on the cloud for many reasons, but mostly to gain access to the latest machine learning infrastructure. Google Cloud TPUs are an example of innovative, rapidly evolving technology to support deep learning, and we found that moving TensorFlow workloads to TPUs has boosted our productivity by greatly reducing both the complexity of programming new models and the time required to train them. Using Cloud TPUs instead of clusters of other accelerators has allowed us to focus on building our models without being distracted by the need to manage the complexity of cluster communication patterns."

In this blog post I am going to explain one of possible way how to implement Deep Learning ML to play video game. The idea behind this machine learning project is to capture images together with action, while you play Mario Kart game. Then captured images are transformed into features of training data set, and action keys into label hot vectors respectively. Since we need to capture images, the emulator should be positioned at fixed location and size during playing the game, as well as during testing algorithm to play game. The flowing image shows N64 emulator graphics configuration settings.

Having TA'd for Machine Learning this semester and worked in the field of Computer Vision and Robotics for the past few years, I always have this feeling that the more I learn the less I know. Therefore, its sometimes good to just sit back and look at the big picture. This post will talk about how I see the relations between these three fields in a high level. First of all, Machine Learning is more a brand then a name. Just like Deep Learning and AI, this name is used for getting funding when the previous name used is out of hype.

Understanding how artificial intelligence works may seem to be highly overwhelming, but it all comes down to two concepts, machine learning, and deep learning. These two terms are usually used interchangeably assuming they both mean the same, but they are not. Both the terms are not new to us, but the way they are utilized to describe intelligent machines has always been changing. It is important for organizations to clearly understand the difference between machine learning and deep learning. By definition, machine learning is a concept in which algorithms parse the data, learn from it, and then apply the same to make informed decisions.

Artificial intelligence can now carry out many of the same cognitive tasks humans can, but we still don't really understand how AIs think. Google DeepMind plans to train long-standing tests of human cognitive skills on machine minds to learn how they work. A long-standing problem in AI research has been the fact that deep neural networks are "black boxes." You can't tell how these algorithms work just by looking at their code. They teach themselves by training on data and there's no simple flow diagram a human can follow.

I've been trying to build a model using the deep learning operator. My dataset has two columns both are text in type and one of them is the attribute and the other one is the label. When I feed this dataset into RapidMiner, it fails at the Deep Learning operator saying "Error while executing the H2O model: {0}" Attached is the error message and the same thing is seen in the logs. Any help would be appreciated. Is there a problem with the way the data is being fed and is there a format other than what I am doing here?

At Tyto.ai we are working on interesting problems which occasionally brings us into contact with VCs and other investors. Most of my machine learning background is in natural language processing (NLP). I love NLP, and I could talk all day about it, but sometimes it is difficult to explain how generalizable the techniques in modern NLP are to areas outside text. It's pretty easy to show how a deep learning model can tell the difference between a dog and a cat, and everyone understands how that is relevant to different image types. But techniques developed for NLP are perhaps even more powerful.

This blog is based on my talk in London at the Re.work Connected City Summit on Deep Learning Applications for Smart cities. The talk is based on a forthcoming paper created with the help of my students atUPM/citysciences on the same theme. Please email me at ajit.jaokar at futuretext.com or follow me @ajitjaokar for more details. Initially, we started off with the usual Smart City approach i.e. domains such as Security – Transport – Health – Governance – Environment etc Then, we were inspired by a statement "Man becomes the sex organs of the machine world – the bee of the plant world – enabling machines to evolve ever new forms" – Marshall McLuhan It indicates that disruptive innovations like Deep Learning and AI cannot be viewed in silos. What can Machines learn from Observations?

Learning to optimize - the idea that we can learn from data algorithms that optimize a numerical criterion - has recently been at the heart of a growing number of research efforts. One of the most challenging issues within this approach is to learn a policy that is able to optimize over classes of functions that are fairly different from the ones that it was trained on. We propose a novel way of framing learning to optimize as a problem of learning a good navigation policy on a partially observable loss surface. To this end, we develop Rover Descent, a solution that allows us to learn a fairly broad optimization policy from training on a small set of prototypical two-dimensional surfaces that encompasses the classically hard cases such as valleys, plateaus, cliffs and saddles and by using strictly zero-order information. We show that, without having access to gradient or curvature information, we achieve state-of-the-art convergence speed on optimization problems not presented at training time such as the Rosenbrock function and other hard cases in two dimensions. We extend our framework to optimize over high dimensional landscapes, while still handling only two-dimensional local landscape information and show good preliminary results.
