With No Laws To Guide It, Here’s How Orlando Is Using Amazon’s Facial Recognition Technology

Davey Alba, Buzzfeed News

The Orlando Police Department has been running tests using Amazon’s face recognition cloud service on 3 surveillance cameras placed in the streets. This article raises valid concerns about the fact that there is no law regulating these activities. What happens to the data of people who are not “persons of interest”? Is police personnel correctly trained to handle the technology? What about the past examples of unregulated mass surveillance impacting the behavior of communities?

It’s hard for citizens to have confidence in a pioneering new program when the leaders don’t seem to fully understand what the hell they’re pioneering.

The poet in the machine: Auto-generation of poetry directly from images through multi-adversarial training – and a little inspiration

Microsoft Research Blog

The point of this research is not to have AI replace poets. It’s about the myriad applications that can augment creative activity and achievement that the existence of even mildly creative AI could represent. Although the researchers acknowledge achieving truly creative AI is yet very far away, the boldness of their project and the encouraging results have been inspiring.

A team of researchers at Microsoft Research Asia attempted to train a research model that generates poems from images directly using an end to end approach. The task of generating accurate captions from images is still an “unsolved” NLP problem but the researchers attempted to do something even harder to pave way for future research in this domain. In the process, the researchers also managed to assemble two poem datasets using living annotators.

How teaching AI to be curious helps machines learn for themselves

James Vincent, The Verge

Last week turned out to be an exciting one for AI researchers, with multiple papers tackling the problem of exploration in reinforcement learning coming about:

The above piece covers one of those papers, which introduced a surprisingly simple approach to tackling one of the outstanding challenges of the field and showed impressive performance.


Concerns & Hype

VeriPol computer tool studies text to identify false police statements

The Engineer

Spain has rolled out a text analysis system that purportedly detects fake robbery claims 8 out of 10 times. The system, named VeriPol, has been tested in the field in 2017, and represents a 15% increase in accuracy compared to human judgement alone. There would not be much concern if the tool was used only as assistance to human police officers, but the following quote appears extremely suspicious:

VeriPol was put to task on a real-life pilot study in the urban areas of Murcia and Malaga in Spain in June 2017. In one week, 25 cases of false robbery reports were detected in Murcia, resulting in the cases being closed, and a further 39 were detected and closed in Malaga. For comparison, over the course of eight years between 2008 and 2016, the average number of false reports detected and cases closed by police officers in the month of June was 3.33 for Murcia and 12.14 for Malaga.

Such high numbers suggest that the police might be far too reliant on the algorithm. The main concern here, as for any computer-based decision, is that VeriPol is being used as a god-like oracle rather than like an error-prone assistant.

Chinese AI will develop Chinese artificial consciousness

Jan Krikke, Asia Times

The first two lines reveal all we need to know about the credibility of this piece.

If the experts are to be believed, AI will develop its own consciousness. A closer look suggests they got it backwards – human consciousness will be embedded in AI.

There is no such consensus in the field, and no “closer look” that would reveal the opposite of this absence of consensus either. What seems to be the main message, that cultural biases get embedded in machine learning algorithms, is buried under strange misconceptions (sampling loss being caused by quantum physics?) and errors that basic fact checking would have eliminated (“Big Blue” did not beat Kasparov, Deep Blue did…). Nothing much to do with consciousness.

Researchers Created an ‘AI Physicist’ That Can Derive the Laws of Physics in Imaginary Universes

Daniel Oberhaus, Motherboard

Researchers from MIT trained an AI model to predict the motion of a body in two-dimensions as accurately as possible. They incorporated four strategies commonly used by scientists: divide-and-conquer, occam’s razor, unification and lifelong learning. The experiments resulted in a massive decrease in error for predicting the motion of a body.


Analysis & Policy

Fed Scours Data for Signs of a Robot Takeover

Jeanna Smialek, Bloomberg

Despite worries about AI and automation leading to widespread unemployment being common, the precursor to that – current workers becoming more productive and able to do more work aided by AI-powered tools – has been curiously missing. The Fed has been looking into this, and has found that the effects of AI on productivity may be tricky to find in the numbers and may also take a while to be fully felt:

“In the footnotes of his speech last week, Clarida cited “Artificial Intelligence and the Modern Productivity Paradox: A Clash of Expectations and Statistics,” a study by Massachusetts Institute of Technology economist Brynjolfsson and co-authors Daniel Rock and Chad Syverson. In it, the trio suggest that the “most impressive” capabilities of AI haven’t yet diffused widely.”

The EU plans to test an AI lie detector at border points

Dani Deahl, The Verge

The EU is running an experimental trial to use AI based lie detectors at border crossing points in Hungary, Latvia and Greece. Given the issues with poor error rates and bias in facial recognition systems, application of such a system could be a problem. For now, the experimental trial cannot prohibit anyone from crossing the border and refers doubtful cases to a human agent.


Expert Opinions & Discussion within the field

AI for social good

Google AI

Google has launched an AI for Social Good program and will fund the best ideas.

The compute and data moats are dead

Stephen Merity, smerity.com

A great piece that discusses large compute and data being significant advantages in the long run in machine learning.

“For machine learning, history has shown compute and data advantages rarely matter in the long run. The ongoing trends indicate this will only become more true over time than less. You can still contribute to this field with limited compute and even data. It is especially true that you can get almost all the advances of the field with limited compute and data. Those limits may even be to your advantage.”
