This thesis reviews numerical optimization methods with machine learning problems in mind. Since machine learning models are highly parametrized, we focus on methods suited for high dimensional optimization. We build intuition on quadratic models to figure out which methods are suited for non-convex optimization, and develop convergence proofs on convex functions for this selection of methods. With this theoretical foundation for stochastic gradient descent and momentum methods, we try to explain why the methods used commonly in the machine learning field are so successful. Besides explaining successful heuristics, the last chapter also provides a less extensive review of more theoretical methods, which are not quite as popular in practice. So in some sense this work attempts to answer the question: Why are the default Tensorflow optimizers included in the defaults?

"Alexa, read us a story." That's one way teachers are using digital assistants, such as the popular Amazon Echo device -- technology that many parents of home-bound students used last year to aid in their children's educational routines -- in the classroom. One school district in California has integrated this technology even further with the Symphony Classroom device from Merlyn Mind, described as the world's first digital assistant for education. The device is powered by Edge AI, combining artificial intelligence with edge computing technology. READ MORE: A digital assistant for educators helps with K–12 classroom management.

Online reinforcement learning (RL) algorithms are often difficult to deploy in complex human-facing applications as they may learn slowly and have poor early performance. To address this, we introduce a practical algorithm for incorporating human insight to speed learning. Our algorithm, Constraint Sampling Reinforcement Learning (CSRL), incorporates prior domain knowledge as constraints/restrictions on the RL policy. It takes in multiple potential policy constraints to maintain robustness to misspecification of individual constraints while leveraging helpful ones to learn quickly. Given a base RL learning algorithm (ex. UCRL, DQN, Rainbow) we propose an upper confidence with elimination scheme that leverages the relationship between the constraints, and their observed performance, to adaptively switch among them. We instantiate our algorithm with DQN-type algorithms and UCRL as base algorithms, and evaluate our algorithm in four environments, including three simulators based on real data: recommendations, educational activity sequencing, and HIV treatment sequencing. In all cases, CSRL learns a good policy faster than baselines.

Welcome to Deep Reinforcement Learning 2.0! In this course, we will learn and implement a new incredibly smart AI model, called the Twin-Delayed DDPG, which combines state of the art techniques in Artificial Intelligence including continuous Double Deep Q-Learning, Policy Gradient, and Actor Critic. The model is so strong that for the first time in our courses, we are able to solve the most challenging virtual AI applications (training an ant/spider and a half humanoid to walk and run across a field). In this part we will study all the fundamentals of Artificial Intelligence which will allow you to understand and master the AI of this course. These include Q-Learning, Deep Q-Learning, Policy Gradient, Actor-Critic and more.

Below are three alternatives to Kaggle which I've become interested in: A fourth competition does exist -- HALITE by Two Sigma-- however, HALITE appears to have been discontinued…you're welcome to check it out on your own; only Battlecode, Terminal, and Lux are summarized below. Battle Code has been around since 2003; the description below is taken directly from the site. Battlecode is a real-time strategy game, for which you will write an AI player. Your AI player will need to strategically manage a robot army and control how your robots work together to defeat the enemy team. As a contestant, you will learn to use artificial intelligence, pathfinding, distributed algorithms, and communications to make your player as competitive as possible.

Microsoft Azure DP-100: Designing and Implementing a Data Science Solution Exam Covered. Learn Azure Machine Learning.

This is a course called "Intelligently Extract Text and Data from a Document with OCR and NER." In this course, you will learn how to make your own Named Entity Recognizer. The main goal of this class is to learn how to find things like invoices, business cards, shipping bills, Bill of Lading documents, and more from scanned documents like this one. However, for the sake of privacy, we only looked at the Business Card. But you can use the same framework to write any kind of financial report.
