We address reinforcement learning problems with finite state and action spaces where the underlying MDP has some known structure that could be potentially exploited to minimize the exploration of suboptimal (state, action) pairs. For any arbitrary structure, we derive problem-specific regret lower bounds satisfied by any learning algorithm. These lower bounds are made explicit for unstructured MDPs and for those whose transition probabilities and average reward function are Lipschitz continuous w.r.t. the state and action. For Lipschitz MDPs, the bounds are shown not to scale with the sizes $S$ and $A$ of the state and action spaces, i.e., they are smaller than $c \log T$ where $T$ is the time horizon and the constant $c$ only depends on the Lipschitz structure, the span of the bias function, and the minimal action sub-optimality gap. This contrasts with unstructured MDPs where the regret lower bound typically scales as $SA \log T$ . We devise DEL (Directed Exploration Learning), an algorithm that matches our regret lower bounds. We further simplify the algorithm for Lipschitz MDPs, and show that the simplified version is still able to efficiently exploit the structure.

Artificial Intelligence is no longer just contained in science fiction films. It is a part of our everyday lives and in our classrooms. As we use tools like Siri and Amazon's Alexa, we are just beginning to see the possibilities of AI in education. And, we should expect to see more. The Artificial Intelligence Market in the US Education Sector 2017-2021 report suggests that experts expect AI in education to grow by "47.50% during the period 2017-2021."

In a world of rapid technological and economic transition, it is now imperative that people engage in lifelong learning. The traditional model, in which people focus their learning on the years before age 25, then get a job and devote little attention to education thereafter, is rapidly becoming obsolete. In the contemporary world, people can expect to switch jobs, see whole sectors disrupted, and need to develop additional skills as a result of economic shifts. The type of work they do at age 30 likely will be substantially different from what they do at ages 40, 50, or 60. As I argue in my new book, "The Future of Work: Robots, AI, and Automation," it will be vital that people develop new capabilities throughout their lives.

Bullying is a serious issue in schools around the world, and the growing popularity of social media can make it harder than ever for victims to find safe spaces. Bullying can lead to low self-esteem, isolation and depression. Even though its effects are very serious, bullying goes unnoticed by a student's parents and teachers for an average of nine months. The goal for WatsomApp, a startup based in Spain, is to prevent and reduce harassment in the classroom. WatsomApp's founders knew that identifying and addressing bullying faster would improve children's learning experiences and quality of life.

Find 16 colors out of millions of colors (24 bit to 4 bit reduction) which represents a picture best, using unsupervised learning algorithm K-means for clustering. You can see the result of my programming exercise at the top. Nice example to visualize how you can reduce highly dimensional problem spaces into something which a computer can handle better without losing the core information.

This problem also appeared as an assignment problem in the coursera online course Mathematics for Machine Learning: Multivariate Calculus. The description of the problem is taken from the assignment itself. In this assignment, we shall train a neural network to draw a curve. The curve takes one input variable, the amount traveled along the curve from 0 to 1, and returns 2 outputs, the 2D coordinates of the position of points on the curve. The below table shows the first few rows of the dataset.

We can see a lot of hype about AI and Machine Learning, and its potential to transform businesses. More and more сompanies are adopting machine learning solutions, setting up accelerators, opening R&D centers, and investing into startups. On the other hand, there are many companies that are using old-fashioned data analytics tools and labeling them as AI. Also,there is a large number of reports with AI market estimates and forecasts. However, it's challenging to get the right information on machine learning development that will actually work for your business. As a company that has delivered successful Machine Learning and Data Science solutions across such industries as Healthcare, Aviation, Media and Entertainment, and Technology, we've decided to talk with our experts and collect top guidelines for making your machine learning development project work.

CHENNAI: Drafting legal contracts -- be it employment documents or the highly complex merger agreements -- has been a constant pain for larger corporates. For smaller enterprises that may not be able to hire legal organisations to vet such documents in detail, it is even harder to manage and map laws to particular contracts. With the development of Artificial Intelligence, legal contract mapping and management has been automated to a large extent and is turning out to be an area of growth for technology start-ups such as SpotDraft, which makes about $5 million in revenue every month. Amid Indian players like VakilSearch, Legal Desk and Near Law, SpotDraft is one of the first few to provide contract management services using Artificial Intelligence. The legal tech start-up, founded by Harvard Law School graduate Shashank Bijapur, along with Madhav Bhagat, a former software developer at Google, looks to expand its operations from its home base in India to European countries, Singapore and Hong Kong, among others, this year to cash in on the rapid growth in the $80 billion contract automation market.

Artificial Intelligence is a broader umbrella under which Machine Learning (ML) and Deep Learning (DL) comes. Diagram shows, ML is subset of AI and DL is subset of ML. AI is composed of 2 words Artificial and intelligence. Anything which is not natural and created by humans is artificial. Intelligence means ability to understand, reason, plan etc.

Various companies collaborate for better future, and International Association of Community Drone Pilots (IACDP) is partnering with a drone pilot community, DroneUp to launch the Responsible Community Pilot program. The RCP program focuses on engaging drone pilots through training, certification, idea-sharing and community. The program will also cover online courses and exams, standard of conduct and detailed safety guidelines. "Our efforts to build this community through training and a sense of purpose are having dramatic positive effects on ensuring air safety," says Tom Walker, CEO and founder of DroneUp. "IACDP is motivated by a desire to make a positive impact on the industry," says John Evans, President of IACDP.
