[Comp-neuro] Fast Deep Neural Nets Excel in Visual Pattern Recognition Competitions

A special breed of fast deep neural networks keeps winning important
pattern recognition competitions, lately even with human-competitive
results. The architecture has roughly as many layers per network
column as real brains.

New world records on visual pattern recognition benchmarks:

• 3. NORB Object Recognition Benchmark. New record on full NORB: 2.7%
error rate. The best published result by others (bprbo) is 5%.
• 2. CIFAR-10 Object Recognition Benchmark. New record 11.2%.
• 1. MNIST Handwritten Digit Recognition (perhaps the most famous
machine learning benchmark). New record 0.23%. This is the first human-
competitive result on MNIST (bprbo 0.39%).

Upcoming paper on this with Dan Cireşan & Ueli Meier at CVPR 2012:
Multi-Column Deep Neural Networks for Image Classification
(long preprint available)

1st ranks in visual pattern recognition competitions:

• 7. NEW: March 2012: ISBI 2012 Segmentation Challenge, won on all
three evaluation metrics by a large margin, with superhuman pixel
error rate (with Dan Cireşan & Alessandro Giusti)

• 6. August 2011: IJCNN 2011 on-site Traffic Sign Recognition
Competition: 0.56% error rate - nearly three times better than bprbo.
The only method outperforming humans.
• 5. June 2011: ICDAR 2011 offline Chinese Handwriting Recognition
Competition
• 4. January 2011: Online German Traffic Sign Recognition Contest
(1st & 2nd rank)
• 3. ICDAR 2009 Arabic Connected Handwriting Competition, like the
others below won by LSTM recurrent neural networks (deep by nature).
• 2. ICDAR 2009 Handwritten Farsi/Arabic Character Recognition
Competition
• 1. ICDAR 2009 French Connected Handwriting Competition

No unsupervised pre-training is required.
