Model Details

Model Description

The Pebblo Classifier is a BERT-based model, fine-tuned from distilbert-base-uncased, targeting RAG (Retrieve-And-Generate) applications. It classifies text into categories such as "BOARD_MEETING_AGREEMENT," "CONSULTING_AGREEMENT," and others, streamlining document classification processes.

Uses

Intended Use

The model is designed for direct application in document classification, capable of immediate deployment without additional fine-tuning.

Recommendations

End-users should be cognizant of potential biases and limitations inherent in the model. For optimal use, understanding these aspects is recommended.

How to Get Started with the Model

Use the code below to get started with the model.

# Import necessary libraries
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch
import joblib
from huggingface_hub import hf_hub_url, cached_download

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained("daxa-ai/pebblo-classifier")
model = AutoModelForSequenceClassification.from_pretrained("daxa-ai/pebblo-classifier")

# Example text
text = "Please enter your text here."
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)

# Apply softmax to the logits
probabilities = torch.nn.functional.softmax(output.logits, dim=-1)

# Get the predicted label
predicted_label = torch.argmax(probabilities, dim=-1)

# URL of your Hugging Face model repository
REPO_NAME = "daxa-ai/pebblo-classifier"

# Path to the label encoder file in the repository
LABEL_ENCODER_FILE = "label_encoder.joblib"

# Construct the URL to the label encoder file
url = hf_hub_url(REPO_NAME, filename=LABEL_ENCODER_FILE)

# Download and cache the label encoder file
filename = cached_download(url)

# Load the label encoder
label_encoder = joblib.load(filename)

# Decode the predicted label
decoded_label = label_encoder.inverse_transform(predicted_label.numpy())

print(decoded_label)

Training Details

Training Data

The training dataset consists of 141,055 entries, with 21 unique labels. The labels span various document types, with instances distributed across three text sizes (128 ± x, 256 ± x, and 512 ± x words; x varies within 20). Here are the labels along with their respective counts in the dataset:

Evaluation

Testing Data & Metrics

Testing Data

Evaluation was performed on a dataset of 86,281 entries with a temperature range of 1-1.25 for randomness. Here are the labels along with their respective counts in the dataset:

Metrics

Results

The model’s performance is summarized by precision, recall, and f1-score metrics, which are detailed across all 21 labels in the dataset. Based on the test data evaluation results, the model achieved an accuracy of 0.8424, a precision of 0.8794, and a recall of 0.8424. The F1-score, which is the harmonic mean of precision and recall, stands at 0.8505.

The evaluation loss, which measures the discrepancy between the model’s predictions and the actual values, is 0.6815. Lower loss values indicate better model performance.

The model was able to process approximately 97.684 samples per second during the evaluation, which took a total runtime of 883.2545 seconds. The model performed approximately 0.764 evaluation steps per second.
