WebMar 28, 2024 · There are two quantization options. First, per output-channel weight quantization, in this case sW ∈Rn+ is a nl−. dimensional vector and each output channel (or neuron) is scaled independently. Second, per-layer (or per-tensor) quantization, where. sW ∈R+ is a scalar value that scales the whole weight tensor W l.

WebOct 13, 2024 · OverQ-Split can represent a value with twice the normal dynamic range, essentially adding one extra bit of representation to affected outliers. The primary advantage of OverQ-Split is its simplicity. We will show later how it can be implemented in a spatial accelerator with only basic muxing logic.

WebWe propose outlier channel splitting, a technique to inference. Clipping is used for the activations to control improve DNN model quantization that does not require the effect of outliers.
