neuroni Il cervello agisce attraverso una rete dinamica di neuroni che si attivano in risposta a stimoli interni ed esterni. Questo sistema permette di controllare i muscoli, regolare le emozioni, pianificare azioni e apprendere nuove competenze
Gradient Descent Algorithm The weights are updated iteratively: \[ w_i := w_i - \eta \frac{\partial L}{\partial w_i} \] \[ b := b - \eta \frac{\partial L}{\partial b} \] where \(\eta\) is the learning rate controlling the step size. Limitations and Solutions
