Neural network
A neural network is a computational model of interconnected, parameterized units that learns transformations from inputs to outputs.
Bayesian Optimization in Action
A neural network is a machine-learning model composed of interconnected computational layers that transform inputs into outputs.
- How it is used
- Uses neural networks to extract features from complex structured data before Gaussian-process similarity modeling.

Ensemble Methods for Machine Learning
A neural network is a parameterized computational model composed of connected units that transform inputs through learned weights and nonlinear functions.
- How it is used
- Uses layered feature construction to model nonlinear relationships with continuous labels.
- How deep it goes
