How do I install HNN in my Haskell project?

You can install HNN via Cabal or Stack by adding it as a dependency in your .cabal file or package.yaml. Detailed installation instructions are available on Hackage, as mentioned in the README.

HNN vs TensorFlow: which is better for Haskell?

HNN is a pure Haskell library focused on type-safe feed-forward networks, ideal for functional programming enthusiasts. TensorFlow offers Haskell bindings but is more extensive; for complex models outside FFNs, TensorFlow might be preferable.

Can I use HNN for deep learning?

HNN supports deep feed-forward networks with multiple layers, but it lacks specialized layers for convolutional or recurrent networks, limiting its applicability to standard deep learning tasks.

What activation functions does HNN support?

While not explicitly listed, HNN likely includes common activation functions like sigmoid, tanh, and ReLU for feed-forward networks. Check the `AI.HNN.FF.Network` module tutorial for specifics.

How to train a neural network with HNN?

Follow the tutorial in the `AI.HNN.FF.Network` module to construct networks, define loss functions, and use automatic differentiation for training via backpropagation, as outlined in the examples.

Is HNN good for production machine learning?

HNN is suitable for production within Haskell ecosystems for feed-forward models, but its limited architecture support and smaller community may pose challenges for scaling or maintaining complex ML systems.

Pros & Cons

Pros

Automatic Differentiation

Uses automatic differentiation for gradient computation, simplifying backpropagation as highlighted in the key features.

Haskell Native Integration

Built as a native Haskell library, enabling seamless use with other Haskell projects and leveraging the language's type system.

Educational Resources

Includes example code and a tutorial in the `AI.HNN.FF.Network` module, providing practical guidance for getting started.

Type-Safe Implementation

Emphasizes Haskell's strong type system to ensure safer neural network constructions, reducing runtime errors.

Cons

Limited Network Types

Only supports feed-forward neural networks, lacking advanced architectures like CNNs or RNNs, which restricts its use for complex tasks.

Ecosystem Maturity

The Haskell machine learning ecosystem is less developed compared to Python, with fewer community resources and pre-trained models.

Performance Scaling

No mention of GPU support in the documentation, implying CPU-only execution that may not scale well for large datasets or deep networks.
