AlexNet is a convolutional neural network for classification.
AlexNet is the name of a convolutional neural network for classification, which competed in the ImageNet Large Scale Visual Recognition Challenge in 2012. **Differences:** - not training with the relighting data-augmentation; initializing - non-zero biases to 0.1 instead of 1 (found necessary for training, as initialization to 1 gave flat loss). **Object categories for classification** [Class ID] **Paper** [ImageNet Classification with Deep Convolutional Neural Networks] **Dataset** [ILSVRC2012] Source Caffe BVLC AlexNet ==> Caffe2 AlexNet ==> ONNX AlexNet **Model input and output** **Input** data_0: float[1, 3, 224, 224] **Output** softmaxout_1: float[1, 1000] **Sample test data** random generated sample test data: - test_data_0.npz - test_data_1.npz - test_data_2.npz - test_data_set_0 - test_data_set_1 - test_data_set_2 **Results/accuracy on test set** The bundled model is the iteration 360,000 snapshot. The best validation performance during training was iteration 358,000 with validation accuracy 57.258% and loss 1.83948. This model obtains a top-1 accuracy 57.1% and a top-5 accuracy 80.2% on the validation set, using just the center crop. (Using the average of 10 crops, (4 + 1 center) * 2 mirror, should obtain a bit higher accuracy.) **Model size: 244 MB** **License** [BSD-3] : https://papers.nips.cc/paper/4824-imagenet-classification-with-deep-convolutional-neural-networks.pdf : http://www.image-net.org/challenges/LSVRC/2012/ :https://contentmamluswest001.blob.core.windows.net/content/14b2744cf8d6418c87ffddc3f3127242/9502630827244d60a1214f250e3bbca7/3c51fb607ec2474c84a0808bfbf9cd59/synsets.txt :https://github.com/onnx/models/blob/master/bvlc_alexnet/LICENSE
