Reconstruction loss measures how well the predicted shape matches the target shape. Compatibility loss measures how good each primitive fits the object part it represents. Proximity loss acts as regularizer to counteract the vanishing gradients. How well does it work? flowtesting tst nhs uk

"WebbIn [5]–[7], the proximity loss due to fundamental fre-quency current has been investigated. However, the inﬂuence of pulsewidth modulation (PWM) on the proximity loss has not been reported in literature.
