What is machine learning / ai? How to learn machine learning in practice? Neural Networks (often referred to as deep learning) are particular interesting. But there are a few questions. To answer these questions and give beginners a guide to really understand them, I created this interesting course.

Organizations are teams of teams. By definition, a manager gets work done not only through one's own resources and efforts, but also through others. In other words, you are required to work effectively with people outside your team. These are individuals and groups within the organization and also outside. You have to influence people at different levels and functions, build collaborative relationships wherever possible, negotiate wisely, handle difficult conversations and make decisions in the face of uncertainty and complexity.

R is a data analysis tool, graphical environment, and programming language. Without any prior experience in programming or statistical software, this video tutorial will help you quickly become a knowledgeable user of R. Now is the time to take control of your data and start producing superior statistical analysis with R. In this video tutorial, you will start with a quick refresher on programming in R. You will learn to set up your R development environment, as well as work on a few simple R programs. After that you will dive right into working with different types of data structures in R, such as vectors, lists, matrices, etc. You will explore how to import and export data for your data analysis project, and also connect to databases such as PostgreSQL.

A new artificial intelligence system is able to recognize higher-level patterns that are consistent across different recipes for producing particular types of materials. A team of materials scientists from the Massachusetts Institute of Technology (MIT) developed the new system that can identify correlations between precursor chemicals used in materials recipes and the crystal structures of the resulting products. The system uses statistical methods that provide a natural mechanism for generating original recipes, which suggest alternative recipes for known materials that accord well with real recipes. The new system learns to perform computational tasks by analyzing large sets of training data. Traditionally, attempts to use neural networks to generate materials recipes have had problems with sparsity and scarcity.

In this interview, Audrow Nash interviews Helen Huang, Joint Professor at the University of North Carolina at Chapel Hill and North Carolina State, about a method of tuning powered lower limb prostheses. Huang explains how powered prostheses are adjusted for each patient and how she is using supervised and reinforcement learning to tune prosthesis. Huang also discusses why she is not using the energetic cost of transport as a metric and the challenge of people adapting to a device while it learns from them. Helen Huang is a Joint Professor of Biomedical Engineering at the University of North Carolina at Chapel Hill and North Carolina State University. Huang directs the Neuromuscular Rehabilitation Engineering Laboratory (NREL), where her goal is to improve the quality of life of persons with physical disabilities.

About this course: Robotic systems typically include three components: a mechanism which is capable of exerting forces and torques on the environment, a perception system for sensing the world and a decision and control system which modulates the robot's behavior to achieve the desired ends. In this course we will consider the problem of how a robot decides what to do to achieve its goals. This problem is often referred to as Motion Planning and it has been formulated in various ways to model different situations. You will learn some of the most common approaches to addressing this problem including graph-based methods, randomized planners and artificial potential fields. Throughout the course, we will discuss the aspects of the problem that make planning challenging.

This course is about artificial neural networks. Artificial intelligence and machine learning are getting more and more popular nowadays. In the beginning, other techniques such as Support Vector Machines outperformed neural networks, but in the 21th century neural networks again gain popularity. In spite of the slow training procedure, neural networks can be very powerful. In the first part of the course you will learn about the theoretical background of neural networks, later you will learn how to implement them.

A problem faced by many instructors is that of designing exams that accurately assess the abilities of the students. Typically these exams are prepared several days in advance, and generic question scores are used based on rough approximation of the question difficulty and length. For example, for a recent class taught by the author, there were 30 multiple choice questions worth 3 points, 15 true/false with explanation questions worth 4 points, and 5 analytical exercises worth 10 points. We describe a novel framework where algorithms from machine learning are used to modify the exam question weights in order to optimize the exam scores, using the overall class grade as a proxy for a student's true ability. We show that significant error reduction can be obtained by our approach over standard weighting schemes, and we make several new observations regarding the properties of the "good" and "bad" exam questions that can have impact on the design of improved future evaluation methods.

Machine learning is more tactical in nature. It imbeds intelligence into business processes to reach decisions more quickly. For example, it can analyze data to learn when to reorder more raw materials based on factors such as inventory, manufacturing productivity or market demand. It can evaluate all of these factors at the same time, much like a human with years of experience predicting when you need to reorder materials -- but can do so in less than a second. The interest in machine learning stems from the number of business applications there are for the technology, and its ability to make AI more practical for enterprises. Deep learning, also known as deep neural networking, takes it a step further and focuses on a narrower subset of AI.

At present, the majority of machine learning jobs involve working with large datasets. You can't do that using a single machine. So, you need to distribute across a cluster. Get acquainted with tools like Apache Hadoop, and cloud services like Rackspace, Amazon EC2, Google Cloud Platform, OpenStack, and Microsoft Azure etc. You should also master all of the great Unix tools such as cat, grep, find, awk, sed, sort, cut, tr etc. Since all of the processing will most likely be the on the Linux-based machine, you need access to learn these tools, their functions, and applications.
