</ul>
<h3id="jan-1112-2020">Jan 11/12, 2020</h3>
<ul>
<li>Master may be a bit unstable wrt to training, these changes have been tested but not all combos</li>
<li>Implementations of AugMix added to existing RA and AA. Including numerous supporting pieces like JSD loss (Jensen-Shannon divergence + CE), and AugMixDataset</li>
<li>SplitBatchNorm adaptation layer added for implementing Auxiliary BN as per AdvProp paper</li>
<li>ResNet-50 AugMix trained model w/ 79% top-1 added</li>
<li><code>seresnext26tn_32x4d</code> - 77.99 top-1, 93.75 top-5 added to tiered experiment, higher img/s than 't' and 'd'</li>
</ul>
<h3id="jan-3-2020">Jan 3, 2020</h3>
<ul>
<li>Add RandAugment trained EfficientNet-B0 weight with 77.7 top-1. Trained by <ahref="https://github.com/michaelklachko">Michael Klachko</a> with this code and recent hparams (see Training section)</li>
<li>Add <code>avg_checkpoints.py</code> script for post training weight averaging and update all scripts with header docstrings and shebangs.</li>
</ul>
<h3id="dec-30-2019">Dec 30, 2019</h3>
<ul>
<li>Merge <ahref="https://github.com/mehtadushy">Dushyant Mehta's</a> PR for SelecSLS (Selective Short and Long Range Skip Connections) networks. Good GPU memory consumption and throughput. Original: <ahref="https://github.com/mehtadushy/SelecSLS-Pytorch">https://github.com/mehtadushy/SelecSLS-Pytorch</a></li>
<li>Add RandAugment trained MixNet-XL weights with 80.48 top-1.</li>
<li><code>--dist-bn</code> argument added to train.py, will distribute BN stats between nodes after each train epoch, before eval</li>
</ul>
<h3id="dec-4-2019">Dec 4, 2019</h3>
<ul>
<li>Added weights from the first training from scratch of an EfficientNet (B2) with my new RandAugment implementation. Much better than my previous B2 and very close to the official AdvProp ones (80.4 top-1, 95.08 top-5).</li>
<li>Brought EfficientNet and MobileNetV3 up to date with my <ahref="https://github.com/rwightman/gen-efficientnet-pytorch">https://github.com/rwightman/gen-efficientnet-pytorch</a> code. Torchscript and ONNX export compat excluded.<ul>
<li>EfficientNet and MobileNetV3 hook based 'feature extraction' classes added. Will serve as basis for using models as backbones in obj detection/segmentation tasks. Lots more to be done here...</li>
<li>HRNet classification models and weights added from <ahref="https://github.com/HRNet/HRNet-Image-Classification">https://github.com/HRNet/HRNet-Image-Classification</a></li>
<li>Reasonable chance I broke something... let me know</li>
</ul>
<h3id="nov-22-2019">Nov 22, 2019</h3>
<ul>
<li>Add ImageNet training RandAugment implementation alongside AutoAugment. PyTorch Transform compatible format, using PIL. Currently training two EfficientNet models from scratch with promising results... will update.</li>
<li><code>drop-connect</code> cmd line arg finally added to <code>train.py</code>, no need to hack model fns. Works for efficientnet/mobilenetv3 based models, ignored otherwise.</li>
