Evaluation summary
We introduce HumanEval for Kotlin, created from scratch by human experts. All HumanEval solutions and tests are written by an expert olympiad programmer with 6 years experience in Kotlin, and independently checked by a programmer with 4 years experience in Kotlin. The tests we implement are eqivalent to the original HumanEval tests for Python, and we fix the prompt signatures to address the generic variable signature we describe above.
How to use
The evaluation presented as dataset which is prepared in a format suitable for MXEval and can be easily integrated into the MXEval pipeline.
During the code generation step, we use early stopping on the }\n} sequence to expedite the process. We also perform some code post-processing before evaluation—specifically, we remove all comments and signatures.
The early stopping method, post-processing steps, and evaluation code are available in the example below.
