+ # 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.
47
+ * **Dataset Link:** [samfatnassi/gaia-dr3](https://huggingface.co/datasets/samfatnassi/gaia-dr3)
48
+
49
+ ### 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
