Potential reason for my PINN's failure to learn the physics behind photovoltaic systems properlyproperly [closed]
I’m currently working on a PINN that predicts the maximum power point (MPP) of solar panels based on irradiance, shading, and temperature. When I train the model, the data loss behaves normally, but ...

Problem in forecast errors when combining tscv and nnetar
I’m encountering an issue when combining tsCV with nnetar (with h = 2 and additional input variables). The forecast errors for both horizons (h = 1 and h = 2) terminate two observations before the end ...

Can I visualize a neural network’s loss landscape to see if it’s stuck in a bad minimum? Any code example for this? [closed]
So, I’m trying to understand why sometimes neural networks get stuck during training. I heard people talk about ‘local minima’ and ‘saddle points,’ but I can’t really picture them. I want to actually ...
