# Technical Data Extraction: Control Effect Analysis (Layer 14)
This document provides a comprehensive extraction of data and trends from the provided image, which consists of eight line charts and one summary heatmap analyzing the "Control effect (d)" across various target and affected axes in a neural network context (Layer 14).
---
## 1. Component Isolation
The image is divided into two primary sections:
- **Section A (Left/Center):** Eight individual line plots showing the "Control effect (d)" over a sequence of "# Examples" (0 to 250).
- **Section B (Right):** A summary heatmap titled "Control effect (d): layer 14" showing the relationship between "Target axis" and "Affected axis."

## 2. Section A: Line Charts (Temporal Trends)
Each of the eight charts follows a consistent format.
- **X-axis:** # Examples (Scale: 0 to 200+)
- **Y-axis:** Control effect (d) (Scale: -0.2 to 0.2)
- **Visual Trend:** In all eight charts, the data series appear as flat lines centered at $y \approx 0$. There is a large grey shaded area (likely representing a confidence interval or range) spanning approximately from -0.25 to 0.25 across all examples.

## 3. Section B: Summary Heatmap
**Title:** Control effect (d): layer 14
**Spatial Grounding:** The legend (color bar) is located on the far right.
- **Red:** Positive values (up to 0.0050)
- **White:** Zero (0.0000)
- **Blue:** Negative values (down to -0.0050)
### Data Table Reconstruction
The heatmap displays the interaction between the **Target axis** (Y-axis) and the **Affected axis** (X-axis). Values are rounded to two decimal places in the cells. A black diagonal staircase line separates the lower-left from the upper-right.
| Target \ Affected | LR | PC1 | PC2 | PC4 | PC8 | PC32 | PC128 | PC512 |
| :--- | :---: | :---: | :---: | :---: | :---: | :---: | :---: | :---: |
| **PC512** | -0.00 | -0.00 | 0.00 | 0.00 | -0.00 | -0.00 | -0.00 | -0.00 |
| **PC128** | -0.00 | 0.00 | -0.00 | -0.00 | -0.00 | 0.00 | -0.00 | -0.00 |
| **PC32** | 0.00 | -0.00 | 0.00 | 0.00 | 0.00 | -0.00 | 0.00 | 0.00 |
| **PC8** | 0.00 | -0.00 | 0.00 | 0.00 | 0.00 | -0.00 | 0.00 | 0.00 |
| **PC4** | 0.00 | -0.00 | 0.00 | 0.00 | 0.00 | -0.00 | -0.00 | -0.00 |
| **PC2** | -0.00 | 0.00 | -0.00 | -0.00 | -0.00 | 0.00 | -0.01 | -0.01 |
| **PC1** | 0.00 | 0.00 | -0.00 | -0.00 | -0.00 | 0.00 | -0.00 | -0.01 |
| **LR** | 0.00 | -0.00 | 0.00 | 0.00 | 0.00 | 0.00 | 0.00 | -0.00 |
### Key Trends and Observations from Heatmap:
1. **Dominant Values:** Most cells contain values of `0.00` or `-0.00`, indicating negligible control effects across most axis pairs.
2. **Significant Deviations:**
- The most intense blue (negative) values are concentrated in the bottom right corner.
- **Target PC2 / Affected PC512:** Shows a value of `-0.01` (Dark Blue).
- **Target PC1 / Affected PC512:** Shows a value of `-0.01` (Dark Blue).
- **Target PC2 / Affected PC128:** Shows a value of `-0.01` (Medium Blue).
3. **Positive Trends:** Subtle red shading (positive values) is visible in the column for **Affected PC128** and **PC512** for targets like PC32 and PC8, though the rounded text still displays `0.00`.
4. **Symmetry:** The effect is not perfectly symmetrical; the influence of PC512 as an "Affected axis" is more pronounced than its influence as a "Target axis."
