# Model Card for Opera Bullet Interpreter

An unofficial United States Air Force and Space Force performance statement "translation" model. Takes a properly formatted performance statement, also known as a "bullet," as an input and outputs a long-form sentence, using plain english, describing the accomplishments captured within the bullet.

This checkpoint is a fine-tuned version of the LaMini-Flan-T5-783M, using the justinthelaw/opera-bullet-completions (private) dataset.

# Model Details

## Model Description

An unofficial United States Air Force and Space Force performance statement "translation" model. Takes a properly formatted performance statement, also known as a "bullet," as an input and outputs a long-form sentence, using plain english, describing the accomplishments captured within the bullet.

This is a fine-tuned version of the LaMini-Flan-T5-783M, using the justinthelaw/opera-bullet-completions (private) dataset.

# Uses

## Direct Use

Used to programmatically produce training data for Opera's Bullet Forge (see GitHub repository for details).

## Downstream Use [Optional]

Used to quickly interpret bullets written by Airman (Air Force) or Guardians (Space Force), into long-form, plain English sentences.

## Out-of-Scope Use

Generating bullets from long-form, plain English sentences. General NLP functionality.

# Bias, Risks, and Limitations

Specialized acronyms or abbreviations specific to small units may not be transformed properly. Bullets in highly non-standard formats may result in lower quality results.

## Recommendations

Look-up acronyms to ensure the correct narrative is being formed. Double-check (spot check) bullets with slightly more complex acronyms and abbreviations for narrative precision.

# Training Details

## Training Data

pre-processing or additional filtering. -->

The model was fine-tuned on the justinthelaw/opera-bullet-completions dataset, which can be partially found at the GitHub repository.

## Training Procedure

### Preprocessing

The justinthelaw/opera-bullet-completions dataset was created using a custom Python web-scraper, along with some custom cleaning functions, all of which can be found at the GitHub repository.

### Speeds, Sizes, Times

It takes approximately 3-5 seconds per inference when using any standard-sized Air and Space Force bullet statement.

# Evaluation

## Testing Data, Factors & Metrics

### Testing Data

20% of the justinthelaw/opera-bullet-completions dataset was used to validate the model's performance.

### Factors

Repitition, contextual loss, and bullet format are all loss factors tied into the backward propogation calculations and validation steps.

### Metrics

ROGUE scores were computed and averaged. These may be provided in future iterations of this model's development.

# How to Get Started with the Model

Use the code below to get started with the model.
