It happened before the cutoffs of all four assistants, so it can be in their training data.
Key facts
- ILSVRC-2012 top-5 test error: 15.3% (runner-up: 26.2%)
- ~60 million parameters, 5 conv + 3 fully connected layers
- Trained on two NVIDIA GTX 580 GPUs
- Used ReLU activations and dropout
- Paper presented at NeurIPS (NIPS) 2012
What happened
AlexNet crushed the ImageNet classification challenge; the team’s startup DNNresearch was acquired by Google in 2013.
Why it matters
The single event most often cited as the start of the modern AI era: it established GPUs + big data + deep nets as the winning recipe and made NVIDIA central to AI.
