近日,由汉口学院教授陈兴博士独自撰写的英文学术专著《MACHINE LEARNING MODEL FOR CORPORATE PERFORMANCE FORECASTING》(ISBN 979-11-988609-4-1)获得韩国人文社会科学研究院(KIHSS)选定,并正式面向海内外公开出版发行。 该专著聚焦企业管理中至关重要的股本回报率(ROE)指标,系统探讨了多种先进的机器学习模型在企业绩效...
This research work investigates a machine learning model to predict the performance of university students on a yearly basis. The model will forecast student performance and help take necessary actions before it is too late. The classification technique is used to train the proposed model using an ...
Q23: What evaluation approaches would you work to gauge the effectiveness of a machine learning model? 问题23:如何评估你的机器学习模型的有效性? 首先你需要将数据分成训练集和测试集,或者使用给交叉验证方法分割。然后你需要选择度量模型表现的metrics,如F1数、准确率、混淆矩阵等。更重要的是,根据实际情况你...
5) Since no labels are provided, there is no specific way to compare model performance in most unsupervised learning methods; 非监督学习: 1)和监督学习相反,非监督学习的主要特征就是无法预先得知变量的名称和类别; 2) ‘聚类’ 概念被常常应用到非监督学习中,也就是我们常常需要去计算‘点’与...
What are performance metrics in machine learning? Machine learning metricshelp you quantify the performance of a machine learning model once it’s already trained. These figures give you an answer to the question,“Is my model doing well?”They help you do model testing right. ...
Conducting regular audits and reviews of the model’s performance can help identify issues or distortions that may have arisen post-deployment and are essential to ensure that the model performs effectively and meets the desired objectives. How Machine Learning Works Machine Learning Algorithms Algorith...
Machine learning models such as XGB, LGBM, and DNN successfully predicted the risk of hypotension and performed better than conventional scoring models such as SOFA, APACHE II, and MOSAIC. The XGB model had the best performance among all models. AUROC was significantly higher in the XGB model ...
Credit risk prediction with and without weights of evidence using quantitative learning models The credit risk assessment process is necessary for maintaining financial stability, cost and time efficiency, model performance accuracy, comparability an...
