Description

A neural network is the parametric model class — composition of affine maps with non-linearities — underlying every deep-learning method. The thesis uses the term in two ways: (a) as a generic synonym for "the learned model" in surveys and high-level claims, and (b) as the concrete fully-connected (MLP) architecture used as a baseline against cnn, lstm, and transformer-attention variants on CSI tasks.

When it's used

  • Baseline classifier on top of hand-crafted CSI features
  • Final regression head on top of CNN/Transformer backbones
  • Theoretical statements about expressivity and capacity

Limitations

  • Plain MLPs underperform structured architectures on CSI sequences
  • Overfit small datasets without regularisation
  • No built-in inductive bias for spatial / temporal structure
