Model Card for Model ID

Intent classification is the act of classifying customer's in to different pre defined categories. Sometimes intent classification is referred to as topic classification. By fine tuning a T5 model with prompts containing sythetic data that resembles customer's requests this model is able to classify intents in a dynamic way by adding all of the categories to the prompt

Model Details

Fine tuned Flan-T5-Base

Model Description

This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated.

  • Developed by: Serj Smorodinsky
  • Model type: Flan-T5-Base
  • Language(s) (NLP): [More Information Needed]
  • License: [More Information Needed]
  • Finetuned from model [optional]: Flan-T5-Base

Model Sources [optional]

How to Get Started with the Model

class IntentClassifier: def init(self, model_name="serj/intent-classifier", device="cuda"): self.model = T5ForConditionalGeneration.from_pretrained(model_name).to(device) self.tokenizer = T5Tokenizer.from_pretrained(model_name) self.device = device

def build_prompt(text, prompt="", company_name="", company_specific=""): if company_name == "Pizza Mia": company_specific = "This company is a pizzeria place." if company_name == "Online Banking": company_specific = "This company is an online banking."

  return f"Company name: {company_name} is doing: {company_specific}\nCustomer: {text}.\nEND MESSAGE\nChoose one topic that matches customer's issue.\n{prompt}\nClass name: "

def predict(self, text, prompt_options, company_name, company_portion) -> str: input_text = build_prompt(text, prompt_options, company_name, company_portion) # print(input_text) # Tokenize the concatenated inp_ut text input_ids = self.tokenizer.encode(input_text, return_tensors="pt", max_length=512, truncation=True).to(self.device)

  # Generate the output
  output = self.model.generate(input_ids)

  # Decode the output tokens
  decoded_output = self.tokenizer.decode(output[0], skip_special_tokens=True)

  return decoded_output

m = IntentClassifier("serj/intent-classifier") print(m.predict("Hey, after recent changes, I want to cancel subscription, please help.", "OPTIONS:\n refund\n cancel subscription\n damaged item\n return item\n", "Company", "Products and subscriptions"))

Training Procedure

https://github.com/SerjSmor/intent_classification/blob/main/t5_generator_trainer.py

Using HF trainer

training_args = TrainingArguments(
    output_dir='./results',
    num_train_epochs=epochs,
    per_device_train_batch_size=batch_size,
    per_device_eval_batch_size=batch_size,
    warmup_steps=500,
    weight_decay=0.01,
    logging_dir='./logs',
    logging_steps=10,
    evaluation_strategy="epoch"
)

trainer = Trainer(
    model=model,
    args=training_args,
    train_dataset=train_dataset,
    eval_dataset=val_dataset,
    tokenizer=tokenizer,
    # compute_metrics=compute_metrics
)

Evaluation

I've used Atis dataset for evaluation. F1 AVG on the train set is 0.69
