Cross-Layer Parameter Sharing in Transformers
Cross-layer sharing is an optimization method in Transformers that falls under the broader family of shared weight and shared activation methods. By sharing elements like Key-Value (KV) activations or attention weights across different layers, this technique reduces both computational demands and memory footprints. For example, a query in a higher layer can directly access the KV cache of a lower-level layer, eliminating redundant activations.

Cross-Layer Parameter Sharing in Transformers
A team of engineers is building a deep neural network to analyze very long text sequences. They discover that the model's size is exceeding their hardware's memory capacity. As a solution, they modify the architecture to make multiple layers use the exact same set of learnable parameters. What is the primary trade-off the engineers must consider with this parameter-sharing approach?
