Researchers use this binary format for several technical reasons:
: It serves as a benchmark to calculate accuracy during training. For instance, the ArcFace model uses it to reach 99.80%+ accuracy on the LFW test. Performance Evaluation : Researchers use scripts like extract_bin.py lfw.bin
With the shift toward web-based datasets (ImageNet, VGGFace2) and streaming data loaders (TensorFlow Data API, PyTorch DataLoader), is lfw.bin obsolete? Researchers use this binary format for several technical
