Tiny-Predictive-Text is a demonstration of predictive text without an LLM, using permy.link. It provides a detailed description of the tool, including its features, benefits, and how to use it. The tool is suitable for a variety of jobs, including content writers, editors, and researchers. It can be used to perform a variety of tasks, such as generating text, completing sentences, and correcting errors.

Quickstart

  1. Include all of the files in the /dist directory as well as dictionary.msgpack and tokens.msgpack in the root of your project.

  2. Add Tiny predict to your HTML.

<script type="module" src="tinypredict.js"></script>
  1. Interface with the library
<script>
  window.addEventListener('tinypredict-ready', () => {
    const input = "I would love to tell you more about";

    window.getPredictiveText(input).then(suggestions => {
      // Use the suggestions object here.
    });
  });
</script>

Suggestions Object

Example suggestions object. The part you'll probably want to use most is prediction which gives you one or more suggested completions in order of quality.

{
  "anchor": "about", 
  "anchor_token": 206, 
  "first_level_context": "tym", 
  "second_level_context": "iwl", 
  "quality": 50,
  "prediction": [
    { "completion": "the", "quality": 55 },
    { "completion": "all of", "quality": 49 }, 
    { "completion": "how we decided", "quality": 45 }
  ]
}

The top-level quality is based only on context-matching while prediction-level quality is based on the context and the prediction quality, so this is the one I recommend using. Note the predictions will come pre-sorted with the highest quality first.

More context on what this object means can be found here

Quality scoring

(See suggestions object above)

While not perfect, the quality score is a rough estimate from 0-100 of how likely the prediction is to be correct. The higher the number, the more likely it is to be correct.

This can be useful if you want your predictions to be less noisy and only show up if a significant threshold of quality has been met.

Training

No GPUs OS requirements or nVidia libraries needed. I run this on my Macbook Pro with the included version of Python.

  • pip install .
  • huggingface-cli login

then

python train.py --retain

To begin the training. Every once in a while it will optimize by pruning word set dictionaries and branches recursively. At this point (look for it in the logs) it will create a new batch file in /training/batches. It does this so the script can be restarted and it can pick up where it left off. Making separate batches also prevents the script from locking up.

Creating the dictionary

The following can be performed at any time, including when the training script is still running. This is useful for just taking a peek at the data so far and playing with it in the web interface.

Once enough batches are created, merge them with

python -m lib.merge_batches

This will merge all the batches and create a msgpack dictionary once all merges have completed.
