📝 Next Sentence Prediction Model

This repository hosts a fine-tuned Flan-T5-Base model optimized for next-line prediction. The model is trained to predict the next sentence in a given text, making it useful for applications like text completion, conversation modeling, and document coherence assessment.

📌 Model Details

Model Architecture: Flan-T5-Base
Task: Next Sentence Prediction
Dataset: OpenWebText-10k (Preprocessed)
Fine-tuning Framework: Hugging Face Transformers
Quantization: FP16 for efficiency

🚀 Usage

Installation

pip install transformers torch datasets

Loading the Model

python

from transformers import T5ForConditionalGeneration, T5Tokenizer
import torch

device = "cuda" if torch.cuda.is_available() else "cpu"

model_name = "AventIQ-AI/flan-t5-base-next-line-prediction"
model = T5ForConditionalGeneration.from_pretrained(model_name).to(device)
tokenizer = T5Tokenizer.from_pretrained(model_name)

Perform Next Sentence Prediction

python

def predict_next_sentence(model, tokenizer, input_sentence):
    device = "cuda" if torch.cuda.is_available() else "cpu"
    formatted_text = f"predict next line: {input_sentence}"
    input_ids = tokenizer(formatted_text, return_tensors="pt").input_ids.to(device)
    
    with torch.no_grad():
        output_ids = model.generate(input_ids, max_length=50)
    
    return tokenizer.decode(output_ids[0], skip_special_tokens=True)

# 🔹 **Test Prediction**
input_sentence = "The sun was setting behind the mountains."
predicted_sentence = predict_next_sentence(model, tokenizer, input_sentence)

print(f"Input Sentence: {input_sentence}")
print(f"Predicted Next Sentence: {predicted_sentence}")

📊 Evaluation Results

After fine-tuning, the model was evaluated on a test set, achieving the following performance:

Metric	Score	Meaning
Perplexity	23	Measures model confidence
Inference Speed	Fast	Optimized for real-time completion

🔧 Fine-Tuning Details

Dataset

The model was trained using the OpenWebText-10k dataset, containing 10,000 documents. The dataset was preprocessed by splitting texts into sentence pairs, where the model learns to predict the next logical sentence.

Training Configuration

Number of epochs: 3
Batch size: 8
Optimizer: AdamW
Learning rate: 2e-5
Evaluation strategy: Epoch-based

Quantization

The model was quantized using FP16, reducing memory usage while maintaining performance.

⚠️ Limitations

The model works best with well-structured sentences.
May struggle with long-range dependencies in texts.
Contextual consistency is limited to sentence pairs.
