Automated Machine Learning Hyperparameter Tuning in Python - DataScienceCentral.com

#artificialintelligence

Tuning machine learning hyperparameters is a tedious yet crucial task, as the performance of an algorithm can be highly dependent on the choice of hyperparameters. Manual tuning takes time away from important steps of the machine learning pipeline like feature engineering and interpreting results. Grid and random search are hands-off, but require long run times because they waste time evaluating unpromising areas of the search space. Increasingly, hyperparameter tuning is done by automated methods that aim to find optimal hyperparameters in less time using an informed search with no manual effort necessary beyond the initial set-up. Bayesian optimization, a model-based method for finding the minimum of a function, has recently been applied to machine learning hyper parameter tuning, with results suggesting this approach can achieve better performance on the test set while requiring fewer iterations than random search.

Hence, it is a good idea to not only pursue certifications in Artificial Intelligence, but also prepare ahead of time for crucial job AI interview questions. Here are some commonly asked ones that will assist you in preparing for the same. Artificial Intelligence is a field of computer science wherein the cognitive functions of the human brain are studied and replicated on a machine or a system.


Heuristic Search for Rank Aggregation with Application to Label Ranking

#artificialintelligence

Rank aggregation for complete rankings: The standard Borda method [10] is a well-established greedy heuristic for RAP, which is intuitive and simple to compute for complete rankings. This method has the advantage of being simple and fast, but the obtained solutions may be far from the true optima.


Algorithms: 3 books in 1 : Practical Guide to Learn Algorithms For Beginners + Design Algorithms to Solve Common Problems + Advanced Data Structures for Algorithms , Vickler, Andy - Amazon.com

#artificialintelligence

Book 1 Have you ever wondered how a programmer develops games and writes code without having to think too much? Do you want to know what makes a programmer confident about the code they write? Do you want to learn how programmers use algorithms to determine how to structure their programs before they develop it? If you did, this is the book for you. An algorithm is a set of rules or instructions you provide to a system.

AI/ML Competitions that aren't Kaggle

#artificialintelligence

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.


Why Player Of Games Is Needed

#artificialintelligence

Hi everyone, today we're going to be comparing Player of Games (PoG) with AlphaZero. PoG is a new AI agent developed by DeepMind and is the first of its kind to achieve high-level performance in both perfect and imperfect information games. With perfect information games, each player knows all the information in the game. For chess and go knowing all the information in the game means players can see both theirs and their opponent's pieces. With imperfect information games, players are unable to see all the information.


Artificial Intelligence -- Breadth-First Search

#artificialintelligence

Artificial Intelligence has a foundational paradigm of agents: these agents exhibit "intelligence". An agent perceives the environment through its sensors; processes the input and performs an intelligent action through its actuators. One example that would illustrate this could be of humans. We perceive the environment through our sensors, i.e. our organs (eyes, ears, nose etc.) and we think about the inputs we've just received, decide on a course of action and act on it using our actuators, i.e. our hands, legs and/or others. In some cases, instantaneous/reflex actions are needed: in case one's hand is in fire, the best possible action would be the reflex action of pulling your arm out of the fire without thinking about it.


Improving Minimax performance

#artificialintelligence

The Minimax algorithm, also known as MinMax, is a popular algorithm for calculating the best possible move a player can player in a zero-sume game, like Tic-Tac-Toe or Chess. It makes use of an evaluation-function provided by the developer to analyze a given game board. During the execution Minimax builds a game tree that might become quite large. This causes a very long runtime for the algorithm. In this article I'd like to introduce 10 methods to improve the performance of the Minimax algorithm and to optimize its runtime.
