Recommendations
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_single')
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 236040 Java methods, containing the code before and after the bug fix was applied. The whole dataset was built from Extracted Bug-Fix Pairs (BFP), extracting single file/single method commits, and keeping only method with less than 512 tokens. An 80/20 train/validation split was applied afterwards.
Training Procedure
Preprocessing [optional]
Remove comments and replace consecutive whitespace characters by a single space.
