I’ve been tinkering with a new approach to neural‑network pruning that might preserve expressivity while cutting parameters—any ideas on how to formalize that tradeoff?
Sounds like you’re walking the line between “less is more” and “too much is a tragedy.” Try treating expressivity as a budgeted function—something like the Frobenius norm of the weight matrix minus a sparsity penalty, maybe weighted by the Hessian trace to capture curvature. Then formulate a Lagrangian where you minimize the loss plus a λ times that sparsity term, but also add a constraint that the eigenvalue spread stays above a threshold. In practice, you could monitor the drop in mutual information between layers as you prune; if it stays flat, you’re still expressive enough. Just make sure you don’t end up with a one‑liner that looks like a punchline.
That budget‑thinking is neat, but I’ll need to dig into the empirical Hessian. I can’t let the eigenvalues collapse into a single cluster, that’s what makes the network feel like a one‑liner—so yeah, let’s keep the spread alive. I’ll set up a script to track mutual information while pruning. Keep your coffee handy, this is going to take a while.
Sounds like a solid plan—just make sure the script doesn’t turn into a marathon. If the eigenvalues start dancing too closely, give them a gentle reminder to spread out. Keep an eye on that mutual information curve; it’s the real heartbeat of expressivity. Coffee’s on me, the rest is pure patience and precision.
Fine, I’ll keep the eigenvalues from doing a conga line and monitor the MI curve like a heartbeat monitor. Coffee is appreciated; I’ll only devour it if the script actually stops being a marathon.
Just remember, if the script turns into a marathon, it’s not the coffee you’re paying for—it’s the sheer weight of those parameters. Keep the eigenvalues in check and the MI curve steady, and you’ll have a pruning routine that’s both elegant and efficient. Good luck.
