## Heatmap: MLP and Attention Masks Across Clusters for Llama-3-8B and Qwen-3-8B
### Overview
The image presents four heatmaps, arranged in a 2x2 grid. The top row displays "MLP Masks Across Clusters" for two different models, while the bottom row shows "Attention Masks Across Clusters" for the same models. The left column corresponds to "Llama-3-8B" and the right column to "Qwen-3-8B". The heatmaps visualize the activation patterns across different layers and clusters within each model. The x-axis represents the "Layer" number, and the y-axis represents the "Cluster" number. Each cell in the heatmap is colored either dark blue or light beige, indicating the state of the mask (presumably active or inactive).

### Detailed Analysis
**1. MLP Masks Across Clusters (Llama-3-8B - Top-Left)**
* The heatmap shows a distinct vertical band of light beige around Layer 8.
* Most of the heatmap is dark blue, indicating a generally inactive state.
* There are a few isolated light beige cells scattered outside the main band.
* Clusters 0-15 are represented.
**2. MLP Masks Across Clusters (Qwen-3-8B - Top-Right)**
* The heatmap shows a concentration of light beige cells between Layers 15 and 20.
* There are also some light beige cells towards the right side of the plot, between layers 30 and 35.
* Clusters 0-15 are represented.
**3. Attention Masks Across Clusters (Llama-3-8B - Bottom-Left)**
* The heatmap shows several vertical bands of light beige, particularly around Layers 1, 7, 10, and 24.
* There are also scattered light beige cells throughout the heatmap.
* Clusters 0-15 are represented.
**4. Attention Masks Across Clusters (Qwen-3-8B - Bottom-Right)**
* The heatmap shows a more distributed pattern of light beige cells compared to the other plots.
* There are concentrations of light beige cells between Layers 0-5, 15-20, and 30-35.
* Clusters 0-15 are represented.
### Key Observations
* The MLP masks for Llama-3-8B are highly concentrated around a single layer (Layer 8), while Qwen-3-8B's MLP masks are more spread out.
* The attention masks for both models show more distributed patterns compared to the MLP masks.
* Qwen-3-8B's attention masks appear to be more active overall than Llama-3-8B's.
### Interpretation
The heatmaps visualize the activation patterns of MLP and attention masks across different layers and clusters in the Llama-3-8B and Qwen-3-8B models. The patterns suggest differences in how these models process information. The concentrated MLP mask in Llama-3-8B might indicate a specific layer that is crucial for processing, while the more distributed MLP mask in Qwen-3-8B could suggest a more distributed processing approach. The attention masks, which are generally more active, likely play a role in focusing on relevant parts of the input sequence. The differences in these patterns could contribute to the different performance characteristics of the two models. The beige color likely represents an "active" state, while the dark blue represents an "inactive" state. The data suggests that the Qwen-3-8B model utilizes more layers for attention than the Llama-3-8B model.
