Awful AI – a curated list of the current scary usages of AI

Awful AI is a curated list to track current scary usages of AI – hoping to raise awareness to its misuses in society

Artificial intelligence in its current state is unfair, easily susceptible to attacks and notoriously difficult to control. Nevertheless, more and more concerning the uses of AI technology are appearing in the wild. This list aims to track all of them. We hope that Awful AI can be a platform to spur discussion for the development of possible contestational technology (to fight back!).

It’s great that someone is working on raising awareness!

How to Analyze Tweet Sentiments with PHP Machine Learning

Machine learning is rarely mentioned in the same sentence (or article, for that matter) with PHP, so each time this happens, I’m all ears. Here’s one that I came across recently – How to Analyze Tweet Sentiments with PHP Machine Learning.

Unlike many other “hello world” kind of examples, this article examines a real and quite common problem, which can be easily adopted to other similar problems – SPAM filtering, marketing segmentation, fraud detection, etc.

How an A.I. ‘Cat-and-Mouse Game’ Generates Believable Fake Photos

The New York Times is running a very fascinating article on the progress of the artificial intelligence and machine learning in both identifying and generating fake photos – How an A.I. ‘Cat-and-Mouse Game’ Generates Believable Fake Photos. The above image shows the progress of the AI working against itself and learning from its own results – one part is trying to identify if the photo is fake or not, and the other part is trying to generate a fake photo which will pass the test. When the test fails, the system learns, improves, and tries again. Look at the last row of photos, which are super realistic and took the system between 10 to 18 days to learn how to generate.

But that’s not all. It gets better, and I quote:

A second team of Nvidia researchers recently built a system that can automatically alter a street photo taken on a summer’s day so that it looks like a snowy winter scene. Researchers at the University of California, Berkeley, have designed another that learns to convert horses into zebras and Monets into Van Goghs. DeepMind, a London-based A.I. lab owned by Google, is exploring technology that can generate its own videos. And Adobe is fashioning similar machine learning techniques with an eye toward pushing them into products like Photoshop, its popular image design tool.

Here are a few more photos that were generated:

This is remarkable. But if you keep reading the article, you’ll quickly discover that there is even more to it. What’s next in line after pictures? You are correct: videos. You better sit down before you watch this video, showing Obama’s lip sync:

So, can’t trust the TV. Can’t trust the Internet. Who do you trust?

PHP-ML – Machine Learning library for PHP

PHP-ML is a machine learning library for PHP. Given, PHP is probably not the best choice when it comes to machine learning, but sometimes one is limited in technology stack choices, so it’s good have options like this one.

Fresh approach to Machine Learning in PHP. Algorithms, Cross Validation, Neural Network, Preprocessing, Feature Extraction and much more in one library.

Here’s the documentation for more details.

Learning Machine Learning and NLP from 187 Quora Questions

Machine Learning is a hot subject these days. And as with any other hot subject, there is a multitude of books, online course, videos, and guides available all over the web. I think that this curated list of 187 Quora questions is an interesting way of approaching the subject.

While Quora has FAQ pages for many topics (e.g. FAQ for Machine Learning), they are far from comprehensive. In this post, I’ve tried to provide a more thorough Quora FAQ for several machine learning and NLP topics.

Quora doesn’t have much structure, and many questions you find on the site are either poorly answered or extremely specific. I’ve tried to include only popular questions that have good answers on general interest topics.
