Model Details

Model Description

A BERT-like model pre-trained on Java buggy code.

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

Fill-Mask.

[More Information Needed]

Downstream Use [optional]

The model can be used for other tasks, like Text Classification.

Out-of-Scope Use

<!-- 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.

from transformers import pipeline
unmasker = pipeline('fill-mask', model='bert-java-bfp_combined')
unmasker(java_code) # Replace with Java code; Use '[MASK]' to mask tokens/words in the code.

Training Details

Training Data

The model was trained on 198088 Java methods, containing the code before and after the bug fix was applied. The whole dataset was built by combining the Dataset of Bug-Fix Pairs for small and medium methods source code. An 80/20 train/validation split was applied afterwards.

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 [optional]

Remove comments and replace consecutive whitespace characters by a single space.

Training Hyperparameters

Speeds, Sizes, Times [optional]

<!-- This section provides information about throughput, start/end time, checkpoint size if relevant, etc. -->

[More Information Needed]

Evaluation

<!-- This section describes the evaluation protocols and provides the results. -->

Testing Data, Factors & Metrics

Testing Data

The model was evaluated on 49522 Java methods, from the 20% split of the dataset mentioned in Training Data

[More Information Needed]

Factors

<!-- These are the things the evaluation is disaggregating by, e.g., subpopulations or domains. -->

[More Information Needed]

Metrics

<!-- These are the evaluation metrics being used, ideally with a description of why. -->

Perplexity

Results

1.48

Summary

Model Examination [optional]

<!-- Relevant interpretability work for the model goes here -->

Environmental Impact

<!-- Total emissions (in grams of CO2eq) and additional considerations, such as electricity usage, go here. Edit the suggested text below accordingly -->

Carbon emissions can be estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019).
