Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Small user base and limited documentation, making it difficult to find help or examples.
WebGL acceleration has limitations, especially with large datasets or complex neural network architectures.
v0.1 to v0.2 migration required significant code rewrites and adjustments in model definitions.
Does not yet support more complex models like transformers or GANs, limiting its use cases.
