# Prompt Structure
Topic %% Customer: text. 
END MESSAGE
OPTIONS: 
each class separated by %
Choose one topic that matches customer's issue.
Class name: 


You have to have a period after the end of the text, otherwise you'll get funky results. That's how the model was trained.

# 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

## 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 Details

### Training Data

<!-- This should link to a Dataset Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->
https://github.com/SerjSmor/intent_classification
HF dataset will be added in the future.

### Training Procedure

<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the 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

<!-- This section describes the evaluation protocols and provides the results. -->
The newest version of the model is finetuned on 2 synthetic datasets and 41 first classes of clinc_oos in a few shot manner.
All datasets have 10-20 samples per class. Training data did not include Atis dataset.

Atis zero shot test set evaluation: weighted F1 87%
Clinc test set is next.
