User-specific future activity prediction in the healthcare domain based on previous activities can drastically improve the services provided by the nurses. It is challenging because, unlike other domains, activities in healthcare involve both nurses and patients, and they also vary from hour to hour. In this paper, we employ various data processing techniques to organize and modify the data structure and an LSTM-based multi-label classifier for a novel 2-stage training approach (user-agnostic pre-training and user-specific fine-tuning). Our experiment achieves a validation accuracy of 31.58\%, precision 57.94%, recall 68.31%, and F1 score 60.38%. We concluded that proper data pre-processing and a 2-stage training process resulted in better performance. This experiment is a part of the "Fourth Nurse Care Activity Recognition Challenge" by our team "Not A Fan of Local Minima".

在软件项目中引入机器学习（ML）组件创造了软件工程师与数据科学家和其他专家合作。虽然合作可以始终具有挑战性，但ML介绍了探索性模型开发过程的额外挑战，需要额外的技能和知识，测试ML系统的困难，需要连续演化和监测，以及非传统质量要求，如公平性和解释性。通过采访来自28个组织的45名从业者，我们确定了在建立和将ML系统部署到生产时面临的关键合作挑战。我们报告了生产ML系统的开发中的共同合作点，以获得要求，数据和集成以及相应的团队模式和挑战。我们发现，这些挑战中的大部分挑战围绕通信，文档，工程和流程以及收集建议以解决这些挑战。
