Question 1

How to implement a transformer model with AI4R in Ruby?

Accepted Answer

Start by reading the transformer guide in the docs and modifying the code in lib/ai4r/neural_network/transformer.rb. It's a minimal implementation supporting encoder-only, decoder-only, and seq2seq modes for hands-on learning.

Question 2

AI4R vs scikit-learn – which is better for learning machine learning?

Accepted Answer

AI4R is ideal for understanding algorithm internals in Ruby with readable code, while scikit-learn offers optimized, production-ready tools in Python. Choose based on your language preference and whether you prioritize transparency over performance.

Question 3

Can AI4R be used for commercial or production projects?

Accepted Answer

Yes, it's unlicensed and free to use, but its educational focus means you'll likely need to optimize or extend the code for production, as it lacks performance tweaks and integration features.

Question 4

How to benchmark classifiers in AI4R?

Accepted Answer

Run the compare_all.rb script in the bench/classifier/ directory, which tests multiple classifiers on datasets and outputs reports, as detailed in the benchmarks overview documentation.

Question 5

What are the hardware requirements for running AI4R neural networks?

Accepted Answer

AI4R runs on CPU only and doesn't support GPU acceleration, so it's best for small-scale experiments on standard hardware, not for intensive deep learning tasks.

Question 6

How to add custom algorithms to AI4R?

Accepted Answer

Extend existing classes or create new ones following the modular structure in lib/, but note that documentation on extension is minimal, requiring reliance on the readable source code for guidance.
