Prognostic Value Of Machine Learningвђ Based Time To Event Analysis Using An ml model for time to event analysis based on random survival forests had higher performance in predicting major adverse cardiovascular events compared with established clinical or ccta derived metrics and a conventional cox model.<b>keywords:< b> machine learning, ct angiography, cardiac, arterie …. Purpose to assess the long term prognostic value of a machine learning (ml) approach in time to event analyses incorporating coronary ct angiography (ccta)–derived and clinical parameters in patients with suspected coronary artery disease. materials and methods the retrospective analysis included patients with suspected coronary artery disease who underwent ccta between october 2004 and.

An ml model for time to event analysis based on random survival forests had higher performance in predicting major adverse cardiovascular events compared with established clinical or ccta derived metrics and a conventional cox model. purpose to assess the long term prognostic value of a machine learning (ml) approach in time to event analyses incorporating coronary ct angiography (ccta. Conclusion: an ml model for time to event analysis based on random survival forests had higher performance in predicting major adverse cardiovascular events compared with established clinical or ccta derived metrics and a conventional cox model. supplemental material is available for this article. Based on our systematic evaluation of machine learning algorithms for continuous time to event survival data we conclude that the cox model can be used as a baseline predictive model.

Using logistic regression is inappropriate and introduces bias. overall, ignoring censoring and using inaccurate evaluation metrics can severely compromise the valid ity of machine learning based prognostic models. care ful consideration of censoring and time to event analysis principles is warranted. abbreviations ai articial intelligence. 2 health science center, xi'an jiaotong university, xi'an, 710061, china. 3 department of urology, the second affiliated hospital of xi'an jiaotong university, xi'an, 710004, china. chongtie@126 . 4 department of urology, the second affiliated hospital of xi'an jiaotong university, xi'an, 710004, china. oliverlee0615@163 . pmid: 38347635.
