But that’s not to say that there hasn’t been progress made. Right now, LeCun is excited about work on a “memory” network that can be integrated into present convolutional neural networks, giving them the ability to retain information. He likens the new mode of memory retention to short term and long term memory in the brain, governed by the hippocampus and cerebral cortex respectively. (LeCun actually detests CNNs being compared to brains, instead preferring a model of a black box with 500 million knobs.) The memory module allows researchers to tell the network a story, and then have it answer questions about the story later. For the story, they used J.R.R. Tolkein’s Lord of the Rings Well, not the entire book, but short summaries of major plot points. (“Bilbo took…
