How do you get HIV?
HIV can be passed on when infected bodily fluid, such as blood or semen, is passed into an uninfected person. Semen is the liquid which is released from a man's penis during sex which carries sperm. It can be infected with HIV or AIDS when someone is HIV positive or is carrying the AIDS virus. This ... |

Professor A: What is the value of \(x + y\) given the following statements?
(1) \(x^2 + y^2 = 5\)
(2) \(xy = 2\)
Professor B: Let's analyze each statement individually first. From statement (1), we have \(x^2 + y^2 = 5\). This equation alone does not give us a unique value for \(x + y\). We can rewrite it as \((x + y)... |

Alice: To convert 905 feet to meters, we use the conversion factor 0.3048 meters per foot. The formula for the conversion is \[ \text{meters} = \text{feet} \times 0.3048 \]. Applying this to 905 feet, we get \[ 905 \, \text{ft} \times 0.3048 \, \text{m/ft} = 275.844 \, \text{m} \].

Student: Hi, I have the expression $\frac{4x-15}{(x+3)(x+2)}$ and I need help with partial fractions. I calculated the coefficients and ended up with $A = -27$ and $B = -23$.

🚀 ZFusionAI Pretraining Dataset
Welcome to the ZFusionAI repository! This dataset is a carefully curated, high-quality collection of text data designed specifically for training small-to-medium-sized language models (in the 500M to 1B parameter range).
By combining general web knowledge, specialized mathematical reasoning, coding proficiency, and Indic language capabilities, this dataset provides a balanced foundation for versatile model performance.
📊 Dataset Composition
We have synthesized four distinct data sources to ensure a balanced distribution of knowledge. The data is processed via weighted interleaving to maintain high structural diversity.
| Data Source | Domain | Weight | Purpose |
|---|---|---|---|
| FineWeb-Edu | General Web / Edu | 30% | General world knowledge & language fluency |
| UltraData-Math | Mathematics | 20% | Logical reasoning & symbolic problem solving |
| Python-Github | Programming | 20% | Syntax, logic, and functional code generation |
| IndicCorpV2 | Tamil (ta) | 30% | Multilingual support & linguistic diversity |
🛠️ Data Processing Pipeline
To ensure the model learns from high-quality tokens, we implemented a rigorous filtering process:
- Streaming Load: Efficient memory management by processing data in streams. 🌊
- Normalization: Harmonized schema (all columns mapped to
text). 🔄 - Length Filtering: Dropped samples with fewer than 30 words to avoid noise. ✂️
- Quality Heuristics: Applied an alphabet/number ratio check (min 30% density) to filter out "junk" characters, HTML boilerplate, and non-informative strings. 🧹
⚙️ How to use
You can load this dataset easily using the Hugging Face datasets library:
from datasets import load_dataset
# Load the ZFusionAI dataset
dataset = load_dataset("GTKING/ZFusionAI_Pretraining_Data", streaming=True)
# Peek at the first example
print(next(iter(dataset)))
💡 Best Practices for 500M-1B Models
Given the parameter count, this dataset is optimized to encourage data efficiency:
- Tokenizer: Ensure you are using a tokenizer compatible with the mixed content (e.g., a byte-level BPE tokenizer) to handle both code and Tamil characters effectively. 🧩
- Epochs: With a dataset of this scale, consider 1–3 epochs depending on your compute budget. ⏳
- Instruction Tuning: While this is a pre-training corpus, it is highly recommended to follow up with an instruction-tuning phase using specialized datasets for optimal chat performance. 🤖
