## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

- **Developed by:** [Thabolezwe Mabandla](http://www.linkedin.com/in/thabolezwe-mabandla-81a62a22b)
- **Model type:** Language Model
- **Language(s) (NLP):** Shona
- **Finetuned from model [optional]:** [FLAN-T5](https://huggingface.co/google/flan-t5-small)

### Model Sources [optional]

<!-- Provide the basic links for the model. -->

- **Repository:** [More Information Needed]
- **Paper [optional]:** [More Information Needed]
- **Demo [optional]:** [More Information Needed]

## 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. -->
> Correction of spelling errors in shona sentences or phrases.

### Direct Use

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

# Bias, Risks, and Limitations

The information below in this section are copied from the model's [official model card](https://arxiv.org/pdf/2210.11416.pdf):

> Language models, including Flan-T5, can potentially be used for language generation in a harmful way, according to Rae et al. (2021). Flan-T5 should not be used directly in any application, without a prior assessment of safety and fairness concerns specific to the application.

## Ethical considerations and risks

> Flan-T5 is fine-tuned on a large corpus of text data that was not filtered for explicit content or assessed for existing biases. As a result the model itself is potentially vulnerable to generating equivalently inappropriate content or replicating inherent biases in the underlying data.

## How to Get Started with the Model

Use the code below to get started with the model.

### Running the model on a CPU

```python

from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("thaboe01/t5-spelling-corrector")
model = T5ForConditionalGeneration.from_pretrained("thaboe01/t5-spelling-corrector")

input_text = "Please correct the following sentence: ndaids kurnda kumba kwaco"
input_ids = tokenizer(input_text, return_tensors="pt").input_ids

outputs = model.generate(input_ids)
print(tokenizer.decode(outputs[0]))
```
