AI milestones in 2012
5 documented milestones from 2012.
Spaun: A Large-Scale Functional Brain Model Capable of Performing Multiple Cognitive Tasks
In November 2012, Chris Eliasmith and colleagues at the University of Waterloo published a description of Spaun (Semantic Pointer Architecture Unified Network) in Science, presenting a 2.5-million-neuron brain model capable of performing eight distinct cognitive tasks, including digit recognition, question answering, and list recall.
AlexNet and Deep Convolutional Neural Networks in Large-Scale Image Classification
In September 2012, Alex Krizhevsky, Ilya Sutskever and Geoffrey Hinton at the University of Toronto submitted a paper describing AlexNet, a deep convolutional neural network that achieved a top-5 error rate of 15.3% on the ImageNet Large Scale Visual Recognition Challenge, outperforming the next-best entry by more than 10 percentage points.
Google Brain Unsupervised Neural Network Learns to Detect Cats from YouTube Frames
In June 2012, Quoc V. Le and colleagues at Google Brain published research showing that a 1,000-machine, 16,000-core neural network trained without labels on 10 million YouTube thumbnail images spontaneously developed a neuron selectively responsive to human and cat faces, demonstrating large-scale unsupervised feature learning from unlabelled video data.
Google Launches Google Now Predictive Information Assistant
Google launched Google Now at Google I/O on 27 June 2012, bundled with Android 4.1 (Jelly Bean). The system used contextual signals (location, search history, calendar entries and travel data) to surface unsolicited, time-relevant information cards without requiring an explicit query.
BrainGate2 Participants Use Thought-Controlled Robotic Arm to Reach and Grasp
In May 2012, researchers in the BrainGate2 clinical trial, led by Leigh Hochberg and colleagues at Massachusetts General Hospital, Brown University, and affiliated institutions, demonstrated that two participants with tetraplegia could use neural signals decoded from a 96-electrode intracortical array to control a robotic arm and perform reach-and-grasp tasks without manual assistance.
