telugu-t5-colloquial

Telugu Chatbot (Mitrabot)

This model is a friendly Telugu chatbot based on the T5 architecture, fine-tuned for conversational responses in Telugu.

Model Description

• Model Type: T5ForConditionalGeneration
• Language: Telugu
• Task: Conversational chatbot
• Fine-tuning Data: [Link to your Hugging Face Dataset, e.g., ankitha29/telugu-colloquial-corpus]
• Library: Transformers

Intended Use

This model is intended for generating conversational responses in Telugu. It can be used in chatbots, dialogue systems, and other applications where natural language interaction is desired.

Training Data

The model was fine-tuned on the [Link to your Hugging Face Dataset]. The dataset contains a variety of Telugu conversational phrases, idioms, rhymes, and poems.

Evaluation Metrics

[Describe how you evaluated your model. For example:]

The model was evaluated using [BLEU score, ROUGE score, or other relevant metrics]. Human evaluation was also used to assess the fluency and naturalness of the generated responses.

Usage

from transformers import T5ForConditionalGeneration, T5Tokenizer

model_name = "ankitha29/telugu-t5-colloquial"  # Replace with your actual model name
tokenizer = T5Tokenizer.from_pretrained(model_name)
model = T5ForConditionalGeneration.from_pretrained(model_name)

input_text = "ఏమి చేస్తున్నారు?"  #What are you doing? (Telugu)
input_ids = tokenizer(input_text, return_tensors="pt").input_ids

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
Use code with caution.

Limitations
[Describe any limitations of your model. For example:]

The model may not perform well on topics outside of its training data. It may also generate incorrect or nonsensical responses in some cases.

**How to Prepare:**

1.  **Replace the Placeholders:** Replace all the bracketed placeholders (`[]`) with accurate information about your model, data, and evaluation.
2.  **Correct Model Class:** Ensure you use `T5ForConditionalGeneration` and `T5Tokenizer` in the code example.
3.  **Hugging Face Repository:** Put this code in a hugging face repository on “Model Card”.
Use code with caution.
Test the Code: Verify that the code example actually works by running it yourself.

3. Create a Hugging Face Space (Demo):

This involves creating a live, interactive demo of your chatbot using Gradio or Streamlit. A space is not necessary but does demonstrate the capabilties of the model.

Here's a Gradio app code and all of your prior code:
