- **Language(s) (NLP):** 
- **License:** Apache 2.0
- **Finetuned from model:** [google/flan-t5-small](https://huggingface.co/google/flan-t5-small)

## Uses

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

### Direct Use

<!-- This section is for the model use without fine-tuning or plugging into a larger ecosystem/app. -->

[More Information Needed]

### Downstream Use [optional]

<!-- This section is for the model use when fine-tuned for a task, or when plugged into a larger ecosystem/app -->

[More Information Needed]

<!-- This section addresses misuse, malicious use, and uses that the model will not work well for. -->

[More Information Needed]

## Bias, Risks, and Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->

[More Information Needed]

### Recommendations

<!-- This section is meant to convey recommendations with respect to the bias, risk, and technical limitations. -->

Users (both direct and downstream) should be made aware of the risks, biases and limitations of the model. More information needed for further recommendations.

## How to Get Started with the Model

Use the code below to get started with the model.

```python
# Load model directly
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("philipp-zettl/t5-small-tydiqa-en")
model = AutoModelForSeq2SeqLM.from_pretrained("philipp-zettl/t5-small-tydiqa-en")

question = "Some question?"
# For instance retrieved using similarity search
context = "A long context ..."

inputs = [f"question: {q} context: {c}" for q, c in [[question, context]]]
model_inputs = tokenizer(inputs, max_length=512, padding=True, truncation=True)
input_ids = torch.tensor(model_inputs['input_ids']).to(device)
attention_mask = torch.tensor(model_inputs['attention_mask']).to(device)
with torch.no_grad():
  sample_output = model.generate(input_ids[:1], max_length=100)
  sample_output_text = tokenizer.decode(sample_output[0], skip_special_tokens=True)
  input_text = tokenizer.decode(input_ids[0], skip_special_tokens=True)
print(f"Sample Input", input_text)
print(f"Sample Output", sample_output_text)
```

## 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. -->
Trained on the english samples of [google-research-datasets/tydiqa](https://huggingface.co/datasets/google-research-datasets/tydiqa) using following code
```python
from datasets import load_dataset

# Load SQuAD dataset
squad_dataset = load_dataset('google-research-datasets/tydiqa', 'secondary_task')

# Split the dataset into training and validation
train_dataset = squad_dataset['train'].filter(lambda e: any([e['id'].startswith(lang) for lang in ['english']]))
validation_dataset = squad_dataset['validation'].filter(lambda e: any([e['id'].startswith(lang) for lang in ['english']]))
```

### Training Procedure

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

#### Preprocessing
Code for preprocessing
```python
def preprocess_batch(batch, tokenizer, max_input_length=512, max_output_length=128):
    questions = batch['question']
    contexts = batch['context']
    answers = [answer['text'][0] for answer in batch['answers']]

    inputs = [f"question: {q} context: {c}" for q, c in zip(questions, contexts)]
    model_inputs = tokenizer(inputs, max_length=max_input_length, padding=True, truncation=True)

    labels = tokenizer(answers, max_length=max_output_length, padding=True, truncation=True)
    model_inputs['labels'] = labels['input_ids']

    return model_inputs

# Tokenize the dataset
train_dataset = train_dataset.map(lambda batch: preprocess_batch(batch, teacher_tokenizer), batched=True)
validation_dataset = validation_dataset.map(lambda batch: preprocess_batch(batch, teacher_tokenizer), batched=True)

# Set format for PyTorch
train_dataset.set_format(type='torch', columns=['input_ids', 'attention_mask', 'labels'])
validation_dataset.set_format(type='torch', columns=['input_ids', 'attention_mask', 'labels'])
