This New Deep Learning Tool Shows You the Most Memorable Parts of Your Photos

Bummed that your latest cat pic didn't get more traction on Instagram? Wondering how to make people to remember your company's logo first and foremost? A clever algorithm developed by MIT computer scientists may be able to help with a new online tool.

Meet MemNet, a new program that uses techniques from the deep learning field of artificial intelligence research in order to determine how memorable our visual media are. This is how it works. Feed MemNet any image, and it will generate a heat map predicting which parts are going to lodge themselves in a human observer's brain. Ultimately, the researchers behind the algorithm would like to turn it into an app that uses memorability prediction to tweak images, rendering them utterly unforgettable.

The latest version of MemNet is available online. Being an amateur cat photographer myself, I decided to give this a try. Apparently, the most memorable part of Mr. Tango Tangerine's face is his left ear:

Deep learning uses systems that mimic neural networks to teach computers new skills, or to train them to search for complex patterns. Typically, this involves asking an algorithm to correlate datasets without any prior human guidance. The computer does so by performing a vast number of iterative computations, and its abilities improving as it processes more data.

These types of techniques are the engine behind numerous innovations from the last decade, including Apple's Siri and Google's auto-complete.

In this case, computer scientists fed MemNet tens of thousands of pictures from several datasets. All of these pictures had been given a "memorability score" based on how well human subjects remembered them in online experiments. After training, the algorithm was pitted against actual people, and asked to predict how memorable a group of never-before-seen images were. It performed 30 per cent better than any existing algorithms, and within a few percentage points of humans.

In other words, MemNet is about as good as people at judging how memorable an image is. It's not hard to imagine MemNet's abilities eventually surpassing our own, given enough training — and this could translate into some seriously clever image editing tools.

If you find the notion of companies using software to ensure that their logos burn a permanent mark in your grey matter somewhat unsettling, bear in mind that this technology has all sorts of non-dystopian applications. It could be used to develop better teaching resources or digital assistant devices that help you remember things you want to remember. Perhaps MemNet will even shed new light on the fundamental nature of human memory, which in turn, could lead to better tools for improving it.

Sure, advertisers probably stand to benefit. But can the marketing world really get much more absurd than it has this week?
