Pruning Process

The model underwent a layer-based pruning process to reduce its size while maintaining performance:

Original model size: 6.60 GB
Pruned model size: 4.71 GB
Size reduction: 28.6%

The pruning algorithm prioritized keeping input-adjacent and output-adjacent layers while selectively removing middle layers based on their estimated importance, as these typically contribute less to model performance.

Model Overview

Model Name: LegalMind Merged Model 3Model Type: Text ClassificationBase Model: BERT-base-uncasedNumber of Labels: 2Merged Models: Combination of multiple fine-tuned .h5 and .safetensors modelsFramework: PyTorch, Transformers (Hugging Face)

Model Description

This model is a fine-tuned BERT-based sequence classification model designed for legal document classification tasks. It has been trained on a mixture of datasets and optimized for real-world applications in the LegalMind project. The final model is an ensemble of multiple .h5 and .safetensors models, merged to leverage knowledge from multiple fine-tuned versions.

Training Details

Dataset: Fine-tuned on legal text classification datasets

Preprocessing: Tokenized using bert-base-uncased tokenizer

Loss Function: Cross-entropy loss

Optimizer: AdamW

Batch Size: 16

Learning Rate: 5e-5

Max Sequence Length: 128

Model Usage

How to Use

from transformers import AutoTokenizer, BertForSequenceClassification import torch

tokenizer = AutoTokenizer.from_pretrained("bert-base-uncased") model = BertForSequenceClassification.from_pretrained("path_to_model")

def classify_text(text): inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True, max_length=128) with torch.no_grad(): outputs = model(**inputs) logits = outputs.logits prediction = torch.argmax(logits, dim=-1).item() return prediction

text = "Example legal document text." print("Predicted Class:", classify_text(text))

Our Model 2 = This is trained with our datasets and has been merged with other best models bringing our Accuracy to almost 98% Our Model 3 = This is our trained model 2 merged with Deepseek R1 - 7B

Inference API

If hosted on Hugging Face:

import requests API_URL = "/static-proxy?url=https%3A%2F%2Fapi-inference.huggingface.co%2Fmodels%2FAbbasgamer1%2FlegalMind%3C%2Fa%3E" headers = {"Authorization": "Bearer YOUR_HF_TOKEN"}

def query(text): payload = {"inputs": text} response = requests.post(API_URL, headers=headers, json=payload) return response.json()

print(query("Example legal document text."))

Model Limitations

Requires GPU for fast inference.

Performance depends on fine-tuning quality and data.

May not generalize well to non-legal text.
