““To make learning easier, we restrict the network so that no visible unit is connected to any other visible unit and no hidden unit is connected to any other hidden unit.””
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
The model limits connections to only between visible and hidden layers, simplifying learning and inference.
In simple terms: Only cross‑layer links are allowed, making training easier.
Key Takeaway
Use this architecture for efficient unsupervised learning.
