Learning weights in a spiking neural network with hidden neurons, using local, stable and online rules, to control non-linear body dynamics is an open problem. Here, we employ a supervised scheme, Feedback-based Online Local Learning Of Weights (FOLLOW), to train a network of heterogeneous spiking neurons with hidden layers, to control a two-link arm so as to reproduce a desired state trajectory. The network first learns an inverse model of the non-linear dynamics, i.e. from state trajectory as input to the network, it learns to infer the continuous-time command that produced the trajectory. Connection weights are adjusted via a local plasticity rule that involves pre-synaptic firing and post-synaptic feedback of the error in the inferred command. We choose a network architecture, termed differential feedforward, that gives the lowest test error from different feedforward and recurrent architectures. The learned inverse model is then used to generate a continuous-time motor command to control the arm, given a desired trajectory.

If you've ever wanted Jetsons to be real, well we aren't that far off from a future like that. If you've ever chatted with automated robots, then you've definitely interacted with machine learning. From self-driving cars to AI bots, machine learning is slowly spreading it's reach and making our devices smarter. Artificial intelligence is the future of computers, where your devices will be able to decide what is right for you. Machine learning is the core for having a futuristic reality where robot maids and robodogs exist.

R is a statistical programming language that allows you to build probabilistic models, perform data science, and build machine learning algorithms. R has a great package ecosystem that enables developers to conduct data visualization to data analysis.This video covers advanced-level concepts in R programming and demonstrates industry best practices. This is an advanced R course with an intensive focus on machine learning concepts in depth and applying them in the real world with R. We start off with pre-model-building activities such as univariate and bivariate analysis, outlier detection, and missing value treatment featuring the mice package. We then take a look linear and non-linear regression modeling and classification models, and check out the math behind the working of classification algorithms. We then shift our focus to unsupervised learning algorithms, time series analysis and forecasting models, and text analytics.

According to the University of Washington professors Carl T. Bergstrom and Jevin West, it's time someone did something about it. It's a free structured course of readings and case studies aimed at giving students (and anyone who might be interested) the tools to look critically at scientific claims driven by data and machine learning. Over the past six months, the two scientists created the syllabus and published it online in the hopes that the UW administration would take notice and turn it into a real class (it's currently winding its way through the approval process, and might be offered as soon as the spring). The two have been frustrated with the way statistical findings are treated in the media and in the classroom for years. West, a professor in the Information School and the director of UW's Data Lab, believes that thanks to the emergence of big data and the increasing availability of tools that help more people work with it, the amount of bullshit appears to have increased; with so much data out there, there is simply more potential for data scientists and designers to shape it to fit their own conclusions–or even intentionally mislead their audience.

Do you want to step into the ever-growing field of data science? Do you wish to equip yourself with one of the most widely used language for data science? Packt's Video Learning Paths are a series of individual video products put together in a logical and stepwise manner such that each video builds on the skills learned in the video before it. Data is on the rise and it's the need of the hour to process it and make sense out it. Analysts and statisticians need to get this job done. It's an art to tactfully and efficiently process data.

For more on derivatives and differentiability, see the rest of that tutorial.) Why do we care that the stack (as a function) is differentiable? Well, we used the "derivative" of the function to move the error around (more specifically... to backpropagate). For more on this, please see the Tutorial I Wrote on Basic Neural Networks, Gradient Descent, and Recurrent Neural Networks. I particularly recommend the last one because it demontrates backpropgating through somewhat more arbitrary vector operations... kindof like what we're going to do here.

This year, the world witnessed significant technology advancements that will have long term implications for our economy and the way we work. Artificial intelligence dominated the list of top courses this year, taking three of the spots in our top 10 list, including the Machine Learning and Deep Learning courses taught by our co-founder Andrew Ng and a Machine Learning course from the University of Toronto. Blockchain has also burst onto the scene, putting Princeton's Bitcoin and Cryptocurrency course at number five on the list.

Which works better for modeling credit risk: traditional scorecards or artificial intelligence and machine learning? Given the excitement around AI today, this question is inevitable. While some new market entrants may have a vested interest in pushing AI solutions, the fact is that traditional scorecard methods and AI bring different advantages to credit risk modeling -- if you know how to use them together. Take, for example, our new credit decisioning solution, FICO Origination Manager Essentials – Small Business. It's designed to help lenders make faster origination decisions without increasing risk.

Reinforcement learning is a body of theory and techniques for optimal sequential decision making developed in the last thirty years primarily within the machine learning and operations research communities, and which has separately become important in psychology and neuroscience. This tutorial will develop an intuitive understanding of the underlying formal problem (Markov decision processes) and its core solution methods, including dynamic programming, Monte Carlo methods, and temporal-difference learning. It will focus on how these methods have been combined with parametric function approximation, including deep learning, to find good approximate solutions to problems that are otherwise too large to be addressed at all.
