🧹 Cleaning Methodology

This dataset was cleaned using a 14-point deep inspection system:

#	Check	What It Detects	Action
1	Empty/missing prompts	Lines with no prompt content	REMOVE
2	Too short (<10 chars)	Prompts too short to be useful	REMOVE
3	Too long (>2000 chars)	Prompts that will truncate in training	FLAG
4	Duplicate prompts	Same prompt appearing multiple times	REMOVE
5	Non-English content	>30% CJK/Arabic characters	REMOVE
6	Control characters	Non-printable bytes (\x00-\x1f)	CLEAN
7	HTML tags	<tag> artifacts from scraping	CLEAN
8	Excessive whitespace	Double spaces, triple newlines	CLEAN
9	URL-only prompts	Prompt is just a URL	REMOVE
10	Binary/garbled data	Non-text content	REMOVE
11	Numbers-only prompts	Prompt contains only digits	REMOVE
12	Truncated prompts	Ends with ... or [truncated]	FLAG
13	Markdown headers	Starts with # (confuses model)	FLAG
14	Missing type field	No category assigned	DEFAULT

📝 Data Format

Each line is a JSONL object:

{"prompt": "Write a function to...", "type": "code_critique"}

Field	Type	Description
prompt	string	The training prompt (cleaned)
type	string	Category: code_critique, safety_helpfulness, reasoning_distilled, competitive_programming, reasoning_tools

💻 Usage

from datasets import load_dataset

# Load the cleaned dataset
ds = load_dataset("Eyght/HH-RLHF-Cleaned-GRPO", split="train")

# Use for GRPO training
for example in ds:
    prompt = example["prompt"]
    # Generate completions and score with reward functions

✅ Verification

• Remaining bugs after cleaning: 0
• All prompts verified: ≥10 chars, valid JSON, no HTML, no control chars
• No duplicates: All prompts unique (case-insensitive)
• Encoding: UTF-8 throughout
• License: mit (same as original)
