I have been watching closely my GPU stats while I explore around in VRChat.
Can anybody tell me why my utilization go from 350 watts 90% ish in worlds I am alone in. But then drop to 100 watts 40% in worlds with lots of people? GPU temps 40c

Model.fit is More Complex Than it Looks
Linear regression’s closed-form solution looks simple, but computing inverse matrix is numerically dangerous. Ill-conditioned matrices, floating-point limits, and squaring the condition number in XᵀX can explode errors. Use SVD-based solver…

Linear regression’s closed-form solution looks simple, but computing inverse matrix is numerically dangerous. Ill-conditioned matrices, floating-point limits, and squaring the condition number in XᵀX can explode errors. Use SVD-based solvers (like model.fit), scaling, L2 regularisation, or iterative methods instead of naive matrix inversion.

covariance matrix XᵀX = V Σ² Vᵀ
That means principal components = right singular vectors from SVD.
The math is beautiful and practical.
