The ImageNet Large Scale Visual Recognition Challenge (ILSVRC) was an image-classification competition where models were compared by top-5 error: how often the correct answer was absent from a model’s five highest-ranked guesses. section 2.0
In 2012, AlexNet achieved 15% top-5 error, compared with about 26% for conventional methods. CNNs then dominated the competition: by 2014, the winning error rate was 6.7%, and by 2017, 29 of 38 teams exceeded 95% top-5 accuracy. section 2.5.5 section 2.0
Figure 2.6 The top-5 error rates in the ILSVRC from 2010 to 2017. SIFT and SVM won in 2010 and 2011, but performance plateaued. CNNs won from 2012 to 2017, including AlexNet in 2012, and eventually saturated the benchmark.
Compare top-5 error rates across the competition’s 2010–2017 results, from early SIFT and SVM entries to CNN winners. section 2.5.5
