DistilBERT with LoRA for Intent Recognition

This is a parameter-efficient fine-tuned version of distilbert-base-uncased using the LoRA technique via PEFT. The model was trained for intent recognition using a custom dataset.

🧾 Model Details

• Base model: distilbert-base-uncased
• Fine-tuning method: LoRA (Low-Rank Adaptation) using 🤗 PEFT
• Task: Intent Recognition (Text Classification)

🧠 Intended Use

You can use this model to classify user intents in applications like chatbots, virtual assistants, or voice-based interfaces.

🏷️ Intent Labels

This model supports classification over 33 intent labels, including:

• BAGGAGE: check_baggage_allowance
• BOARDING_PASS: get_boarding_pass, print_boarding_pass
• CANCELLATION_FEE: check_cancellation_fee
• CHECK_IN: check_in
• CONTACT: human_agent
• FLIGHT: book_flight, cancel_flight, change_flight, check_flight_insurance_coverage, check_flight_offers, check_flight_prices, check_flight_reservation, check_flight_status, purchase_flight_insurance, search_flight, search_flight_insurance
• PRICES: check_trip_prices
• REFUND: get_refund
• SEAT: change_seat, choose_seat
• TIME: check_arrival_time, check_departure_time
• TRIP: book_trip, cancel_trip, change_trip, check_trip_details, check_trip_insurance_coverage, check_trip_offers, check_trip_plan, check_trip_prices, purchase_trip_insurance, search_trip, search_trip_insurance

📥 How to Use

from transformers import AutoTokenizer, AutoModelForSequenceClassification, pipeline
from peft import PeftModel
import joblib

# Load tokenizer and base model
tokenizer = AutoTokenizer.from_pretrained("hopjetair/intent")
base_model = AutoModelForSequenceClassification.from_pretrained("distilbert-base-uncased",num_labels=33)

# Load LoRA adapter
model = PeftModel.from_pretrained(base_model, "hopjetair/intent")

# Load label encoder
label_encoder = joblib.load("label_encoder.pkl")

# Inference
text = "Book me a flight to New York"
clf = pipeline("text-classification", model=model, tokenizer=tokenizer)
result = clf(text)[0]
label_num = int(result["label"].split("_")[-1])
# Convert back to label
predicted_label = label_encoder.inverse_transform([label_num])[0]
print(predicted_label)

🖥️ Minimum Requirements for CPU Inference

You can run DistilBERT inference on:

• ⚙️ Modern desktop or laptop CPUs
• ☁️ Cloud VMs (e.g., AWS t3.medium, GCP e2-standard)
• 🧩 Even on low-end devices (with some latency trade-off)
