The CIA once trained cats to be Cold War spies

Popular Science

Project Acoustic Kitty went about as well as you'd expect. The CIA tried to train cat spies. Breakthroughs, discoveries, and DIY tips sent six days a week. Here's the scene: A man wearing a trench coat and a fedora sits on a park bench, looking up frequently from his newspaper to cast furtive glances at passersby. A stray cat wanders by.


Games with loot boxes to get minimum 16 age rating across Europe

BBC News

Games which feature loot boxes will soon be given an age rating of 16 across Europe, including in the UK, under a host of changes by the European video game ratings organisation. The Pan-European Game Information body (PEGI)'s age ratings are displayed on games sold in the UK and other countries in Europe to indicate their suitability for children of different ages. Loot boxes are an in-game feature allowing players to buy random mystery items with real or virtual currency, but recent research has found they blur the line between gaming and gambling. The new ratings, taking effect from June, could see games containing loot box systems, such as EA Sports FC, receive a much higher age rating. The PEGI system is used in 38 countries to help consumers and particularly parents make informed decisions about the games they purchase.






Optimistic optimization of a Brownian

Neural Information Processing Systems

We address the problem of optimizing a Brownian motion. We consider a (random) realization $W$ of a Brownian motion with input space in $[0,1]$. Given $W$, our goal is to return an $\epsilon$-approximation of its maximum using the smallest possible number of function evaluations, the sample complexity of the algorithm. We provide an algorithm with sample complexity of order $\log^2(1/\epsilon)$. This improves over previous results of Al-Mharmah and Calvin (1996) and Calvin et al. (2017) which provided only polynomial rates.


Improving Exploration in Evolution Strategies for Deep Reinforcement Learning via a Population of Novelty-Seeking Agents

Neural Information Processing Systems

Evolution strategies (ES) are a family of black-box optimization algorithms able to train deep neural networks roughly as well as Q-learning and policy gradient methods on challenging deep reinforcement learning (RL) problems, but are much faster (e.g.
