As a result, the ability to accurately reconstruct absent or corrupt signals can greatly enhance critical patient care. The 2010 PhysioNet/Computing in Cardiology Challenge required participants to develop algorithms to reconstruct a missing 30-second portion of a signal. The Challenge dataset consisted of 300 multiparameter records, each containing six to eight 10-minute, continuous physiological signals. Among the highest-scoring algorithms were neural networks and adaptive/Kalman filtering. Although both algorithms scored well in the competition, these methods used significant amounts of training data from each record, 8 minutes and 5.5 minutes, respectively. Different techniques, such as Recurrent Neural Networks, have been proposed in the literature since the Challenge for multiparameter signal reconstruction, with varying success. We analyzed the performance of these existing algorithms and developed a new Long Short-Term Memory (LSTM) network that produces reconstructions with a relatively short training time (8 seconds). The LSTM network performed comparably well to these algorithms in terms of reconstruction accuracy for three out of the four signal types evaluated (arterial blood pressure, plethysmograph, and respiratory signals), and also had the advantage of drastically reducing the training time needed to achieve accurate signal reconstructions to a mere 8 seconds.","PeriodicalId":113773,"journal":{"name":"Proceedings of the 53rd ACM Technical Symposium on Computer Science Education V. 2","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125096300","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}

Many neurodiverse students (e.g., with ADHD, autism) are enrolled in CS programs, but few graduate. These students often struggle to communicate their needs to instructors, who themselves are often untrained to support neurodiverse students' needs. This can result in instructors unintentionally using practices that are detrimental to student success, lowering students' sense of belonging in CS. Likewise, this can make teaching frustrating for instructors who are unprepared for students' needs. This BoF will provide a platform for instructors and neurodiverse graduates from CS programs to discuss major topics relating to instructor and student needs, such as: experiences working with neurodiverse students, successful strategies, and instructors' professional development needs. Instructors attending will learn more about other instructors' experiences and teaching practices, as well as an NSF-funded participatory design study on training instructors to improve neurodiverse students' retention in undergraduate CS. Participants will be invited to stay up-to-date on the project's progress after the conference, with free access to tools and curriculum as they are developed. Notes and recordings from this discussion will be included as data in our study to support future instructors.","PeriodicalId":113773,"journal":{"name":"Proceedings of the 53rd ACM Technical Symposium on Computer Science Education V. 2","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127715732","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}

TAs perform various duties, including grading, facilitating labs and tutorials, supporting collaboration projects, and, in some cases, designing course materials. TAs often receive training to enhance their technical skills but, more recently, some TA training programs have begun to recognize and emphasize the need for skills that help TAs foster inclusive learning spaces. Because TAs often have more opportunities to interact directly with students and hold dual identities as students and teachers in the same community, how they address and mitigate non-inclusive behavior may be different than how faculty would. While some TAs are beginning to receive training on concepts like self-efficacy, growth mindset, equity, inclusion, and bias, our community needs a deeper understanding of what skills TAs need to cultivate inclusive spaces and how these skills can be developed and evaluated within the constraints of the teaching term. In this BOF, we will discuss the skills and competencies that faculty and TAs believe are essential for helping TAs foster inclusive learning spaces, how to teach those skills and competencies in TA training programs, and how to evaluate the effectiveness of those programs.","PeriodicalId":113773,"journal":{"name":"Proceedings of the 53rd ACM Technical Symposium on Computer Science Education V. 2","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128340355","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}

We emulate proof writing in novice programmers by having them explain their solution to logic puzzles in the first week of an intro course, as this contains many of the skills used in proof writing without requiring any prerequisite knowledge of mathematical structures. An isomorphic question is asked at the conclusion and checked for improvement. We correlate with their performance in the cs class. To ensure that the improvement is related to the cs course material, other factors (prior math courses, GPA et al) are controlled. Computer science majors typically cover material in logic and proof, either as part of programming course, or as a separate computer class. Conventional wisdom would hold that there are a variety of overlapping skill sets between the subject of logic/proof and writing efficient error-free code, and so instructors rely on this intuition to justify introducing (and in fact frequently requiring) this content to introductory programmers. Our study checks for transfer of skills between computer science and proof writing, as no approach to these logic problems is ever directly a part of the content matter in the computer class. Early results of isomorphic questioning from the start and end of the summer quarter indicate a highly statistically significant correlation, even controlling for other factors such as mathematical background and academic strength.","PeriodicalId":113773,"journal":{"name":"Proceedings of the 53rd ACM Technical Symposium on Computer Science Education V. 2","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130285541","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}
