Analysis tools

Interactive visualization

Produces an interactive HTML to view the statistics collected by each quantizer during calibration.

Quantization analyzer

QuantAnalyzer analyzes your pre-trained model and points out sensitive layers to quantization in the model. It checks model sensitivity to weight and activation quantization, performs per layer sensitivity and MSE analysis. It also exports per layer encodings min and max ranges and statistics histogram for every layer.

Layer output generation

This API captures and saves intermediate layer-outputs of a model. This allows layer-output comparison between quantization simulated model (QuantSim object) and actually quantized model on target-device to debug accuracy miss-match issues at the layer level.
