Researchers have developed new methods for compressing trained neural networks, focusing on sigmoid networks. The proposed techniques involve clustering neurons and merging them based on their responses. One method uses a data-free contribution-weighted averaging, while another estimates representative neuron weights and biases using a least-squares approach by mapping neuron responses back to the pre-activation space via the inverse activation function. Both data-assisted and data-free strategies were examined, with findings suggesting that weight information is crucial for clustering and activation information is key for representative-neuron reconstruction during the merging process.
