For years, science-fiction moviemakers have been making us fear the bad things that artificially intelligent machines might do to their human creators. But for the next decade or two, our biggest concern is more likely to be that robots will take away our jobs or bump into us on the highway. Now five of the world's largest tech companies are trying to create a standard of ethics around the creation of artificial intelligence. While science fiction has focused on the existential threat of A.I. to humans, researchers at Google's parent company, Alphabet, and those from Amazon, Facebook, IBM and Microsoft have been meeting to discuss more tangible issues, such as the impact of A.I. on jobs, transportation and even warfare. Tech companies have long overpromised what artificially intelligent machines can do.

University of Southampton researchers have demonstrated that memristors, or resistors that remember their previous resistance, can power a neural network. And since the memristors will remember previous states when turned off, they should use much less power than conventional circuitry -- ideal for Internet of Things devices that can't afford to pack big batteries. The far-simpler memristor array in this test was limited to looking for patterns. You could have sensors that know how to classify objects and identify patterns without human help, which would be particularly helpful in dangerous or hard-to-reach places.

If you wanted AI that could replicate the brain in its full glory, you'd need "hundreds of billions" of synapses (if not more). The far-simpler memristor array in this test was limited to looking for patterns. However, the Southampton group is quick to note that you wouldn't need to go that far for narrower purposes. You could have sensors that know how to classify objects and identify patterns without human help, which would be particularly helpful in dangerous or hard-to-reach places. You might just see IoT gadgets that are not only connected to the outside world, but can make sense of it.

Recently, we presented how to load alpha signals into a research notebook, preprocess them, and then train a Machine Learning classifier to predict future returns. This was done in a static fashion, meaning we loaded data once over a fixed period of time (using the run_pipeline() command), split into test and train, and predicted inside of the research notebook. This leaves open the question of how to move this workflow to a trading algorithm, where run_pipeline() is not available. Here we show how you can move your ML steps into a pipeline CustomFactor where the classifier gets retrained periodically on the most recent data and predicts returns. This is still not moving things into a trading algorithm, but it gets us one step closer.

Machine Learning is one of the most exciting fields in the world. Every week we discover something new, something amazing, something revolutionary. It's incredible, but it can also be overwhelming. That's why we created This Week in Machine Learning! Each week we publish a curated list of Machine Learning stories as a resource to help you keep pace with all these exciting developments.

Data analysis seeks to learn from experience. Better inferences require better thinking and better tools. Practical advice about how to make more credible conclusions based on data. What we can expect in the future, and what we should aspire to in the future.

The CIA claims to be able to predict social unrest days before it happens thanks to powerful super computers dubbed Siren Servers by the father of Virtual Reality, Jaron Lanier. CIA Deputy Director for Digital Innovation Andrew Hallman announced that the agency has beefed-up its "anticipatory intelligence" through the use of deep learning and machine learning servers that can process an incredible amount of data. "We have, in some instances, been able to improve our forecast to the point of being able to anticipate the development of social unrest and societal instability some I think as near as three to five days out," said Hallman on Tuesday at the Federal Tech event, Fedstival. This Minority Report-type technology has been viewed skeptically by policymakers as the data crunching hasn't been perfected, and if policy were to be enacted based on faulty data, the results could be disastrous. The CIA deputy director said that it was "much harder to convey confidence for the policymaker who may make an important decision from advanced analytics with deep learning algorithms."

Ask a random person for an example of an AI system and chances are he or she will name self-driving vehicles. In this episode of the O'Reilly Data Show, I sat down with Shaoshan Liu, co-founder of PerceptIn and previously the senior architect (autonomous driving) at Baidu USA. We talked about the technology behind self-driving vehicles, their reliance on rule-based decision engines, and deploying large-scale deep learning systems.

An Uber self-driving Ford Fusion sits at a traffic light on Beechwood Boulevard and waits to turn onto Fifth Avenue in Pittsburgh. Among the tenuous notions that have sprouted amid the fervor for autonomous vehicles is that Detroit and Silicon Valley are entwined in a titanic battle for supremacy. What is occurring is a very positive cross-pollination between two hubs of innovation. It is not a zero-sum game in which one industry will win and the other lose. There will be winners -- and occasionally losers -- all over the map.

San Francisco (AFP) - Major technology firms are racing to infuse smartphones and other internet-linked devices with software smarts that help them think like people. The effort is seen as an evolution in computing that allows users to interact with machines in natural conversation style, telling devices to tend to tasks such as ordering goods, checking traffic, making restaurant reservations or searching for information. The artificial intelligence (AI) component in these programs aims to make create a world in which everyone can have a virtual aide that gets to know them better with each interaction. Google is making a high-profile push into AI, with the internet titan's chief referring to it as a force for change as powerful as powerful as smartphones. Google Assistant software is being built into new Pixel handsets -- aiming to outdo Apple's Siri -- enabling users to organize and use information on the devices and in the cloud -- to check emails, stay up to date on calendar appointments, news or ask for traffic and weather data.
