Neural networks have become a hot topic over the last few years, but evaluating the most efficient way to build one is still more art than science. In fact, it’s more trial and error than art. However, MIT may have solved that problem.

The NAS (Neural Architecture Search, in this context) algorithm they developed “can directly learn specialized convolutional neural networks (CNNs) for target hardware platforms — when run on a massive image dataset — in only 200 GPU hours,” MIT News reports. This is a massive improvement over the 48,000 hours Google reported taking to develop a state-of-the-art NAS algorithm for image classification. The goal of the researchers is to democratize AI by allowing researchers to experiment with various aspects of CNN design without needing enormous GPU arrays to do the front-end work. If finding state of the art approaches requires 48,000 GPU arrays, precious few people, even at large institutions, will ever have the opportunity to try.

The MIT Technology Review has an interesting article on one specific way that quantum computing can revolutionize machine learning.

Feature matching is a technique that converts data into a mathematical representation that lends itself to machine-learning analysis. The resulting machine learning depends on the efficiency and quality of this process. Using a quantum computer, it should be possible to perform this on a scale that was hitherto impossible.

We typically imagine robots looking like humans, but there’s a real advantage to other “form factors” that mimic pack animals.

For example, check out this new robot that MIT just made: a mini cheetah robot, the first four-legged robot to do a backflip.

At only 20 pounds the limber quadruped can bend and swing its legs wide, enabling it to walk either right side up or upside down. More practically, the robot can also trot over uneven terrain about twice as fast as an average person’s walking speed.
