In particular, language models (LMs) trained on code form the backbone of a majority of these applications, spanning tasks such as code completion, summarization, refactoring, execution prediction, and test generation. These tasks require reasoning about both the syntax and semantics of code. Recent work has shown that language models learn to capture the syntactic properties of code, but it is unclear to what extent they can reason about the semantics of code. In this work, we explore the ability of 3 language models of code to reason about a specific kind of semantics: numerical and logical properties of code. We propose several probing tasks to test the numerical and logical reasoning abilities of these models. We find that the models we explore - CodeBERT, GraphCodeBERT and CodeGen do indeed learn many numerical and logical properties of code, such as finding maximum in a list of numbers, comparing numbers, evaluating boolean expressions and representing numbers. They do not perform as well on complex tasks such as evaluating arithmetic expressions and substituting variables in such expressions. Our results indicate that while these models hold promise, there is a lot of room for improvement of their numeric and logical reasoning abilities.","PeriodicalId":166762,"journal":{"name":"2023 IEEE/ACM International Workshop on Interpretability and Robustness in Neural Software Engineering (InteNSE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133402592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we explore the impact of an unsuperivsed feature enrichment approach based on variable roles on the performance of neural models of code. The notion of variable roles (as introduced in the works of Sajaniemi et al. [1], [2]) has been found to help students' abilities in programming. In this paper, we investigate if this notion would improve the performance of neural models of code. To the best of our knowledge, this is the first work to investigate how Sajaniemi et al.'s concept of variable roles can affect neural models of code. In particular, we enrich a source code dataset by adding the role of individual variables in the dataset programs, and thereby conduct a study on the impact of variable role enrichment in training the Code2Seq model. In addition, we shed light on some challenges and opportunities in feature enrichment for neural code intelligence models.","PeriodicalId":166762,"journal":{"name":"2023 IEEE/ACM International Workshop on Interpretability and Robustness in Neural Software Engineering (InteNSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130075659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neural models are opaque and finding such features sheds light on a better understanding of their predictions. In contrast, in this work, we present an inverse perspective of distractor features: features that cast doubt about the prediction by affecting the model's confidence in its prediction. Understanding distractors provide a complementary view of the features' relevance in the predictions of neural models. In this paper, we apply a reduction-based technique to find distractors and provide our preliminary results of their impacts and types. Our experiments across various tasks, models, and datasets of code reveal that the removal of tokens can have a significant impact on the confidence of models in their predictions and the categories of tokens can also play a vital role in the model's confidence. Our study aims to enhance the transparency of models by emphasizing those tokens that significantly influence the confidence of the models.","PeriodicalId":166762,"journal":{"name":"2023 IEEE/ACM International Workshop on Interpretability and Robustness in Neural Software Engineering (InteNSE)","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132323119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
