The discussion: Rosa: That entropy allocation idea in ASR seems crucial for understanding where the model bottlenecks, but I’m less clear on how those new metrics actually differ from what we used in the earlier work concerning speech encoder pruning. Dev: The paper suggests a multi-stage training strategy to control that allocation dynamically; it implies that static regularization methods fail when the input distribution shifts mid-training, which is something I see often in our noise robustness testing. Are you thinking about how parameter efficiency scales when you introduce those intermediate stages? Taro: I'm more interested in the practical signal processing side—specifically VM-ARRAYDPS; if we can augment microphone arrays with virtual sensors, does that fundamentally change the required spectral density assumptions we make for traditional beamforming, or is it just a linear gain adjustment? Rosa: It’
