If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
For most of the businesses, the role of data in planning, operations and strategy is not just about competitive differentiator, but more about competitive necessity to survive in today's cutthroat business ecosystem. Computer and data driven (predictive) analytics are extensively powering most of the critical business decisions in finance, marketing, customer support and sales. However, data analytics today doesn't come into action when it comes to managing people and making decisions as how we attract, grow, retain and motivate our people. Also, many companies refrain from using data for addressing critical concerns like which team is likely to have performance problems and the reasons behind those issues? How to improve managerial efficiency?

Intel aims to deliver up to 100x reduction in the time to train a deep learning model over the next three years compared to GPU solutions. Intel reinforces commitment to an open AI ecosystem through an array of developer tools built for ease of use and cross-compatibility, laying the foundation for greater innovation. Intel announces AI strategy to drive breakthrough performance, democratize access and maximize societal benefits.
Can artificial intelligence win a championship or that much coveted Gold medal for an individual athlete? Well, one company has not one but two solutions that incorporates artificial intelligence (AI) technology into sports wearables. PIQ is a start-up based in France that has been working for two years to develop this AI interface. The company has poured more than $18 million into this project and has currently a team of 50 engineers working on AI interface that informs the athlete's own "winning factors", while also pinpointing key strengths and strategy for success. According to PIQ, connected sports are limited as they just capture basic data.
Earlier this year, we used DataRobot, a machine learning platform, to test a large number of preprocessing, imputation and classifier combinations to predict out-of-sample performance. In this blog post, I'll take some time to first explain the results from a unique data set assembled from strategies run on Quantopian. Quants run backtests to assess the merit of a strategy, academics publish papers showing phenomenal backtest results, and asset allocators at hedge funds take backtests into account when deciding where to deploy capital and who to hire. The lift-chart below shows that the regressor does a pretty good job at predicting OOS Sharpe ratio.
We'll explore three different methods of optimizing hyperparameters: grid search, random search, and Bayesian optimization. While less common in machine learning practice than grid search, random search has been shown to find equal or better values than grid search within fewer function evaluations for certain types of problems. When comparing stochastic optimization strategies, we consider the distribution of the best found values over many optimizations of a single strategy and apply a statistical test, similar to the test commonly used when comparing CTR distributions across variations in an A/B test. When two optimizations with the same fixed number of function evaluations result in similar best found values we can break ties by determining which optimization strategy was able to observe the best result first.

Marketing automation platforms save time, improve efficiency and increase productivity; but, they do not provide deep insight into the 2.5 quintillion bytes of data being created every day as people move from screen to screen consuming information and making buying decisions. In November 2013, IBM introduced the Watson Ecosystem Program, opening up Watson as a development platform and giving companies the ability to build applications powered by Watson's cognitive computing intelligence. Watson is a cognitive technology that processes information more like a human than a computer -- by understanding natural language, generating hypotheses based on evidence, and learning as it goes. Rather than simply automating manual tasks, artificial intelligence adds a cognitive layer that infinitely expands marketers' ability to process data, identify patterns, and build intelligent strategies and content faster, cheaper and more effectively than humans.
SigOpt offers Bayesian optimization as a service to minimize the amount of trial and error required to find good structural parameters for DNNs and CNNs. After hyperparameter optimization was completed for each method, we compared accuracy using a completely held out data set (SHVN test set, 26k images) using the best configuration found in the tuning phase. Using SigOpt to optimize deep learning architectures instead of a standard approach like random search can translate to real savings in the total cost of tuning a model. Development and innovation is often slowed by the complexity and effort required to find optimal structure and training strategies for deep learning architectures.
It include algorithms such as Linear Regression, Logistic Regression, Decision Tree, Random Forest etc. This includes Decision Trees, Random Forest. In this article, I've explained machine learning algorithms to a soldier in terms of war, battle, and strategy. Do you find watching battle, wars interesting?
