RVFL networks utilize fixed-weight approach called 'stochastically assigned immutable weights' for faster training times and lower computational cost.
Adaptive RVFL (ARVFL) architecture combines quick training with dynamic weight adaptation, improving performance in analyzing medical images and predicting financial trends.
RVFL networks have direct input-output mapping, simplified training, and avoid settling at local minima, but face challenges in handling complex patterns.
ARVFL integrates adaptive mechanisms to enhance learning efficiency by refining feature representations and expanding the model's ability to distinguish complex patterns.
