A Complete Guide To The New 'Crypto Wars'

Slashdot - Wed, 27/04/2016 - 10:01am
blottsie writes: The latest debate over encryption did not begin with a court order demanding Apple help the FBI unlock a dead terrorist's iPhone. The new "Crypto Wars," chronicled in a comprehensive timeline by Eric Geller of the Daily Dot, dates back to at least 2003, with the introduction of "Patriot Act II." The battle over privacy and personal security versus crime-fighting and national security has, however, become a mainstream debate in recent months. The timeline covers a wide-range of incidents where the U.S. and other allied governments have tried to restrict citizens' access to strong encryption. The timeline ends with the director of national intelligence blaming NSA whistleblower Edward Snowden for advancing the spread of user-friendly, widely available strong encryption.

A Majority Of Millennials Now Reject Capitalism, Poll Shows

Slashdot - Wed, 27/04/2016 - 7:01am
A new poll shows that a majority of young people do not support capitalism. The study was conducted by Harvard University, which polled young adults ages 18-29. It found that 51 percent of those polled rejected capitalism, that is to say, they did not support it. Only 42 percent said they support capitalism -- there was a margin of error of 2.4 percentage points. When asked what alternative system they would prefer, there wasn't a clear winner. Just 33 percent said they supported socialism. When talking about politics or economics, it can get complicated and the poll does little to shed light on what parts of capitalism young people dislike or what parts of socialism young people like. It does appear to suggest young people are frustrated with the status quo and are more focused on the flaws of free markets.

Public beta of toolkit for developing machine learning for robots and games released

OpenAI (a non-profit AI research company sponsored by Elon Musk and others) has released the public beta of OpenAI Gym, a toolkit for developing and comparing algorithms for reinforcement learning (RL), a type of machine learning.

OpenAI Gym consists of a growing suite of environments (from simulated robots to Atari games), and a site for comparing and reproducing results. OpenAI Gym is compatible with algorithms written in any framework, such as Tensorflow and Theano. The environments are initially written in Python (other languages planned).

If you’d like to dive in right away, you can work through a tutorial, and you help out while learning by reproducing a result.

What is reinforcement learning?

Reinforcement learning (RL) is the subfield of machine learning concerned with decision making and motor control. It studies how an agent can learn how to achieve goals in a complex, uncertain environment. It’s exciting for two reasons, according to OpenAI’s Greg Brockman and John Schulman:

  • RL is very general, encompassing all problems that involve making a sequence of decisions: for example, controlling a robot’s motors so that it’s able to run and jump, making business decisions like pricing and inventory management, or playing video games and board games. RL can even be applied to supervised learning problems with sequential or structured outputs.
  • RL algorithms have started to achieve good results in many difficult environments. RL has a long history, but until recent advances in deep learning, it required lots of problem-specific engineering. DeepMind’s Atari resultsBRETT from Pieter Abbeel’s group, and AlphaGo all used deep RL algorithms, which did not make too many assumptions about their environment, and thus can be applied in other settings.

However, RL research is also slowed down by two factors:

  • The need for better benchmarks. In supervised (human-managed) learning, progress has been driven by large labeled datasets like ImageNet. In RL, the closest equivalent would be a large and diverse collection of environments. However, the existing open-source collections of RL environments don’t have enough variety, and they are often difficult to even set up and use.
  • Lack of standardization of environments used in publications. Subtle differences in the problem definition, such as the reward function or the set of actions, can drastically alter a task’s difficulty. This issue makes it difficult to reproduce published research and compare results from different papers.

OpenAI Gym is an attempt to fix both problems.

Partners include:

More information, including enviroments (Atari games, 2D and 3D robots, and toy text, for example) is available here.

“During the public beta, we’re looking for feedback on how to make this into an even better tool for research,” says the OpenAI team. “If you’d like to help, you can try your hand at improving the state-of-the-art on each environment, reproducing other people’s results, or even implementing your own environments.
