The move to elevate Cyber Command to a full Unified Combatant Command and split it off from the National Security Agency or NSA shows that cyber intelligence collection and information war are rapidly diverging fields.

Google researchers have developed Google Vizier, an artificial intelligence (AI) system that automatically tunes other AI programs.

The researchers note machine-learning programs need carefully set “hyperparameters,” which are determined in advance and are adapted to the problem at hand. Although this is often a difficult and time-consuming task, Google Vizier makes the process easier by automatically optimizing the hyperparameters of machine-learning models.

The Google researchers say they have “used Vizier to perform hyperparameter tuning studies that collectively contained millions of trials for a research project.”

Google Vizier uses a process called “transfer learning,” in which the algorithm uses data from previous studies as a guide and then suggests optimal hyperparameters for new algorithms.

The researchers tested the Google Vizier system by giving cookie recipes to the contractors who make the puddings in Google’s canteen. The researchers taste-tested the result and tracked the changes the chefs made to improve the taste.

Researchers at the University of Massachusetts, Amherst (UMass) warn some artificial intelligence (AI) programs are inheriting biases against certain dialects, which could lead to automatic minority discrimination as language-based AI systems proliferate.

The researchers compiled 59.2-million Twitter messages with a high likelihood of containing African-American slang or vernacular, and then filtered them through several natural-language processing tools. They found one popular tool classified the posts as Danish, while several common machine learning-based application programming interfaces that analyze text for meaning and sentiment also had problems.

“If you purchase a sentiment analyzer from some company, you don’t even know what biases it has in it,” says UMass professor Brendan O’Connor. “We don’t have a lot of auditing or knowledge about these things.”

Some experts are concerned the AI prejudice problem may be more widespread than many people realize, with such systems increasingly influencing decisions in finance, healthcare, and education.

Best books to get introduced to AI

I’m a secondary school student and find AI fascinating. However it’s not taught at school and I don’t really know where to start. Are there any books anyone would recommend to get me started and introduced to the subject. And then perhaps books to read once I’ve finished them so I can delve deeper into the subject. Thanks
