What is DenseNet architecture?

DenseNet connects every layer to every later one via concatenation, reusing features to cut parameters and fight vanishing gradients.

How does DenseNet compare to ResNet?

DenseNet uses denser connections and channel concat over ResNet's skips and sums, yielding 2-4x fewer params at similar accuracy.

Yes for efficiency-focused tasks like edge AI; pairs well with transformers in hybrids, but pure attention models lead on raw benchmarks.
