Testing Neural Programs
share
Deep neural networks have been increasingly used in software engineering and program analysis tasks. They usually take a program and make some prediction about it, e.g., bug prediction. We call these models neural programs. The reliability of neural programs can impact the reliability of the encompassing analyses. In this paper, we describe our ongoing efforts in developing effective techniques to test neural programs. We discuss the challenges in developing such tools and our future plans. In our preliminary experiment on a recent neural model proposed in the literature, we found that the model is very brittle and simple perturbations in the input can cause the model to make a mistake in its prediction.
