## Diagram: Knowledge Hierarchy in Transformer Circuits
### Overview
The image is a diagram illustrating a hierarchical flow of knowledge within transformer circuits, ultimately influencing model parameters. It depicts how transformer circuits lead to abstract and specific knowledge, which then branches into implicit memory, explicit memory, and external information, all contributing to the final model parameters.
### Components/Axes
* **Boxes:** Represent different types of knowledge or components.
* **Arrows:** Indicate the flow of information or influence.
* **Colors:** Used to distinguish different levels or categories in the hierarchy.
* **Blue:** Represents higher-level knowledge.
* **Green:** Represents memory and information types.
* **Red:** Represents model parameters.
* **Text Labels:** Describe the type of knowledge or component within each box.
### Detailed Analysis
The diagram can be broken down into the following components:
1. **Transformer Circuits (Top):**
* A blue box at the top labeled "Transformer circuits."
* This is the starting point of the diagram.
2. **Separable Knowledge (Middle-Top):**
* A light blue box encompassing "Abstract knowledge" and "Specific knowledge" and labeled "Separable knowledge" on the right.
3. **Abstract and Specific Knowledge (Middle):**
* Two blue boxes branching from "Transformer circuits":
* Left box: "Abstract knowledge"
* Right box: "Specific knowledge"
4. **Memory Hierarchy (Middle-Bottom):**
* A light green box encompassing "Implicit memory", "Explicit memory", and "External information" and labeled "Memory hierarchy" on the right.
5. **Memory and Information Types (Bottom):**
* Three green boxes branching from "Specific knowledge":
* Left box: "Implicit memory"
* Middle box: "Explicit memory"
* Right box: "External information"
6. **Model Parameters (Bottom):**
* A red box at the bottom labeled "Model parameters."
* "Abstract knowledge" flows directly into "Model parameters" with a solid black arrow.
* "Implicit memory" flows directly into "Model parameters" with a solid black arrow.
* "Explicit memory" flows into "Model parameters" with a dashed black arrow.
### Key Observations
* The diagram illustrates a hierarchical structure, starting from transformer circuits and leading to model parameters.
* The flow of information is primarily top-down.
* Abstract and specific knowledge are separated but both contribute to the memory hierarchy and ultimately the model parameters.
* There are three types of memory/information: implicit, explicit, and external.
* Explicit memory has a dashed line connection to model parameters, suggesting a different or less direct influence compared to implicit memory.
### Interpretation
The diagram represents a conceptual model of how knowledge is processed and utilized within transformer circuits to influence model parameters. It suggests that transformer circuits generate both abstract and specific knowledge. Specific knowledge is further categorized into implicit memory, explicit memory, and external information. All these elements ultimately contribute to shaping the model parameters. The dashed line from "Explicit memory" to "Model parameters" might indicate a weaker or more indirect influence compared to the solid lines from "Abstract knowledge" and "Implicit memory". The diagram highlights the importance of different types of knowledge and memory in the functioning of transformer-based models.
