# 🐻 Mesosfer Bear AI - Multi-Stage Foundation Corpus
This repository contains the curated, structured-shuffled (`seed=42`), and 95% Train / 5% Validation split corpus used to pretrain and align **Mesosfer Bear AI** (a 16-layer transformer LLM optimized for high-efficiency training on AMD Instinct MI300X).

## 🛠️ Data Preprocessing & Splitting Protocol
- **Structured Deterministic Shuffling**: Every individual shard is shuffled with `seed=42` using zero-copy PyArrow array indexing to prevent gradient correlation and eliminate loss spikes.
- **95% Train / 5% Validation Split**: Every single domain shard is partitioned into `train/` and `val/` directories.
- **Sequence Length Target**: Built for `max_seq_len = 4096` tokens with `<|endoftext|>` sequence packing.
## 🚀 Quickstart: Loading Data in Python
```python
from datasets import load_dataset
# Load Pretrain Bahasa Indonesia Train Split
dataset = load_dataset('Dummy9898/bear-dataset', data_dir='pretrain/bahasa_umum_id/train')
print(dataset)
```
