Pruning Binarized Neural Networks: A Dedicated Framework and Globally Weighted Algorithms

The paper presents a PyTorch-based framework for designing and optimizing binarized neural networks, incorporating freezing and pruning mechanisms. It introduces a novel pruning method that uses a global weighting scheme to assess parameter importance across abstraction levels, achieving a 70% pruning rate on VGG11 without sacrificing accuracy—outperforming existing binarized pruning results of 41%. The framework facilitates rapid, reproducible evaluation and prototyping of state‑of‑the‑art binarized network techniques.

Deep Microcompression: Structured Pruning and Bit-packed Quantization for Microcontrollers

Deep Microcompression (DMC) is a hardware‑aware pipeline that combines structured pruning, quantization‑aware training, and fixed‑length bit‑packing to enable deep learning inference on bare‑metal microcontrollers. The method achieves a 55.8× weight compression on LeNet‑5 while maintaining 98.77% accuracy, and produces a dependency‑free C library with deterministic latency. On the RP2040 Cortex‑M0+ microcontroller, DMC cuts binary size threefold compared to TensorFlow Lite while matching its accuracy, and it is the first documented deployment of a standard CNN on the 2 KB SRAM ATmega328P.

Towards Efficient Convolutional Neural Network for Embedded Hardware via Multi-Dimensional Pruning

arXiv:2607. 11473v1 Announce Type: cross Abstract: In this paper, we propose TECO, a multi-dimensional pruning framework to collaboratively prune the three dimensions (depth, width, and resolution) of convolutional neural networks (CNNs) for better execution efficiency on embedded hardware.
