Suppose for a ML classification problem X, I have three labels, i.e. 1, 0 and -1. For some reasons, I obtained bad accuracy. So I decided to change the number of labels to two, i.e. 1 and -1. That way I got much better result. Now, when I am in the prediction phase, I want first to find what is my threshold level for precision/recall. If the prediction is not within those levels, assume 0. Programmatically, what is the proper way to establish that threshold?

Hi I am a very experienced statistician, data scientist and academic writer. I have completed several PhD level thesis projects involving advanced statistical analysis of data. Relevant Skills and Experience I have worked with data from several companies and have done projects involving high level quantitative analysis and data interpretation skills to study the trends, time behaviour Proposed Milestones $250 CAD - a and compare the variables in the data. I can do advanced level analysis in SPSS, R, PYTHON, WEKA, TABLEAU and EXCEL tools like machine learning, hypothesis testing, forecasting, T-test, ANOVA etc. Looking forward to discussion, Best Regards, Suyash

It is purely depend on the class distribution, if it is case of imbalanced classification, then different set of metric and algorithms will work. One has to explore dataset and its characteristics Relevant Skills and Experience I have worked on such projects numerous times as my full time responsibilities of data scientist include working on various business problems using data analytics techniques Proposed Milestones $155 CAD - complete
