• Abstract summary: This paper systematically investigates the generation of code explanations by Large Language Models (LLMs) Our findings reveal significant variations in the nature of code explanations produced by LLMs, influenced by factors such as the wording of the prompt. A consistent pattern emerges for Java and Python, where explanations exhibit a Flesch-Kincaid readability level of approximately 7-8 grade.

• Abstract: This paper systematically investigates the generation of code explanations by Large Language Models (LLMs) for code examples commonly encountered in introductory programming courses. Our findings reveal significant variations in the nature of code explanations produced by LLMs, influenced by factors such as the wording of the prompt, the specific code examples under consideration, the programming language involved, the temperature parameter, and the version of the LLM. However, a consistent pattern emerges for Java and Python, where explanations exhibit a Flesch-Kincaid readability level of approximately 7-8 grade and a consistent lexical density, indicating the proportion of meaningful words relative to the total explanation size. Additionally, the generated explanations consistently achieve high scores for correctness, but lower scores on three other metrics: completeness, conciseness, and specificity.

  We focus on the cross-lingual capabilities of code embeddings across different programming languages. Code embeddings comprise two distinct components: one deeply tied to the nuances and syntax of a specific language, and the other remaining agnostic to these details. We show that when we isolate and eliminate this language-specific component, we witness significant improvements in downstream code retrieval tasks.

  We evaluate language understanding capacities on simple inference tasks that most humans find trivial.

The models exhibit moderate to low performance on these evaluation sets.

  Reasoning about code and explaining its purpose are fundamental skills for computer scientists. The ability to describe at a high-level of abstraction how code will behave over all possible inputs correlates strongly with code writing skills. Existing pedagogical approaches that scaffold the ability to explain code, such as producing code explanations on demand, do not currently scale well to large classrooms.

  Given a natural language input, the goal is to generate a graph such as an event -- or a reasoning-graph. Existing approaches serialize the output graph as a flat list of nodes and edges. We show that when we instead frame structured commonsense reasoning tasks as code generation tasks, pre-trained LMs of code are better structured commonsense reasoners than LMs of natural language.
