# SADIM: Stellar Intelligence Framework
|
| 16 |
+
|
| 17 |
+
**SADIM-V2** is a specialized AI model trained on the **Gaia Data Release 3 (DR3)** catalog. It bridges the gap between massive raw astronomical observations and actionable scientific insights.
|
| 18 |
+
|
| 19 |
+
**Research Objectives**
|
| 20 |
+
|
| 21 |
+
• Galactic Archaeology: Identifying stellar streams and ancient structures.
|
| 22 |
+
|
| 23 |
+
• Big Data Optimization: Providing an AI-ready interface for 1B+ records.
|
| 24 |
+
|
| 25 |
+
• Scalability: Real-time stellar analysis for future space surveys.
|

+
### 1. Technical Feature Map
|
| 30 |
+
The model is designed to process 13 fundamental astronomical parameters:
|
| 31 |
+
|
| 32 |
+
| Feature Name | Description |
|
| 33 |
+
| :--- | :--- |
|
| 34 |
+
| **source_id** | Unique Gaia DR3 Identifier |
|
| 35 |
+
| **ra / dec** | Celestial Equatorial Coordinates |
|
| 36 |
+
| **l / b** | Galactic Coordinates (Disk Alignment) |
|
| 37 |
+
| **pmra / pmdec** | Kinematics (Proper Motion Velocity) |
|
| 38 |
+
| **d_pc** | Distance in Parsecs (1/parallax) |
|
| 39 |
+
| **x, y, z** | 3D Heliocentric Cartesian Mapping |
|
| 40 |
+
| **abs_m** | Absolute Magnitude (Intrinsic Brightness) |
|
| 41 |
+
| **bp_rp** | Color Index (Temperature Indicator) |
|
| 42 |
+
|
| 43 |
+
### 2. When to use the Model vs. the Dataset?
|
| 44 |
+
|
| 45 |
+
* **Use the SADIM-V2 77M Model:** For fast inference, predicting missing stellar properties, or automating the classification of new astronomical data.
|
| 46 |
+
* **Use the Gaia-DR3 Dataset:** For deep-dive research, historical record querying, or training your own custom neural networks.

+
### 3. Quick Start (Python)
|
| 50 |
+
Since the dataset contains over **1 Billion records**, we recommend using **Streaming Mode**:
|
| 51 |
+
|
| 52 |
+
```python
|
| 53 |
+
from datasets import load_dataset
|
| 54 |
+
from transformers import AutoModel
|
| 55 |
+
|
| 56 |
+
# 1. Access the Data
|
| 57 |
+
dataset = load_dataset("samfatnassi/gaia-dr3", split="train", streaming=True)
|
| 58 |
+
|
| 59 |
+
# 2. Load the Model
|
| 60 |
+
model = AutoModel.from_pretrained("KilmaAI/SADIM-V2")
|
| 61 |
+
|
| 62 |
+
# Fetch a sample star
|
| 63 |
+
sample_star = next(iter(dataset))
|
| 64 |
+
print(f"Analyzing Star ID: {sample_star['source_id']}")
|
| 65 |
+
