This is a tutorial and survey paper on unification of spectral dimensionality reduction methods, kernel learning by Semidefinite Programming (SDP), Maximum Variance Unfolding (MVU) or Semidefinite Embedding (SDE), and its variants. We first explain how the spectral dimensionality reduction methods can be unified as kernel Principal Component Analysis (PCA) with different kernels. This unification can be interpreted as eigenfunction learning or representation of kernel in terms of distance matrix. Then, since the spectral methods are unified as kernel PCA, we say let us learn the best kernel for unfolding the manifold of data to its maximum variance. We first briefly introduce kernel learning by SDP for the transduction task. Then, we explain MVU in detail. Various versions of supervised MVU using nearest neighbors graph, by class-wise unfolding, by Fisher criterion, and by colored MVU are explained. We also explain out-of-sample extension of MVU using eigenfunctions and kernel mapping. Finally, we introduce other variants of MVU including action respecting embedding, relaxed MVU, and landmark MVU for big data.

Taught by Professor Mausam of the Indian Institute of Technology, Delhi, it discusses the philosophy of AI and how to model a new problem as an AI problem. It describes a variety of basic components of AI, such as search and logic, which can be used to model and solve a new problem. It also teaches many primary algorithms (a process or set of rules) to solve each formulation. The course prepares a student to take a variety of advanced courses in various subfields of AI. This teaches you the meaning of common AI terminology.

To optimize your chances of success in this program, we recommend intermediate Python programming knowledge and basic knowledge of probability and statistics. In this lesson, you will learn about supervised learning, a common class of methods for model construction. In this lesson, you will learn the foundations of neural network design and training in TensorFlow. In this lesson, you will learn to implement unsupervised learning methods for different kinds of problem domains.

Today, artificial intelligence and machine learning are two popular terms that have been often used interchangeably to describe an intelligent software or system. Even though both AI and ML are based on statistics and mathematics, they are not the same thing. Many people have been confused by these two terms. In this article, you will learn the distinctions between AI and ML with vivid examples. Artificial intelligence, or AI, is the ability of a computer or machine to mimic or imitate human intelligent behavior and perform human-like tasks.

In this article, you will learn. Clustering is the most common form of unsupervised learning on unlabeled data to clusters objects with common characteristics into discrete clusters based on a distance measure. Hierarchical Clustering is either bottom-up, referred to as Agglomerative clustering, or Divisive, which uses a top-down approach. A bottom-up approach where each data point is considered a singleton cluster at the start, clusters are iteratively merged based on similarity until all data points have merged into one cluster. Agglomerative clustering agglomerates pairs of clusters based on maximum similarity calculated using distance metrics to obtain a new cluster, thus reducing the number of clusters with every iteration.

The 524 Gateway Timeout error came out when I and Manuel Guzman (MSW R&D director) were testing an ML application that took few minutes to generate results and send them back to the user. It turns out that a timeout value in CloudFlare should be increased to fix this error. We looked of course on Cloudflare documentation on Q&A blogs on how to fix the error and the answer was that it is impossible to increase the timeout (Check this StackOverflow answer). With a little bit of brainstorming, we were able to resolve the issue following Manuel's idea. In this article, I will share with you all the steps we took to tackle the 524 Gateway Timeout Error in Cloudflare.

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.

This tutorial presents two essential concepts in data science and automated learning. One is the machine learning pipeline, and the second is its optimization. These two principles are the key to implementing any successful intelligent system based on machine learning. A machine learning pipeline can be created by putting together a sequence of steps involved in training a machine learning model. It can be used to automate a machine learning workflow.
