Senior Project Manager Information Technology and Services Enterprise (\> 1000 emp.) 3/13/2023 "DecisionTree.jl helps to implement Classification and Regression Tree in few simple steps" 4.5/5 What do you like best about DecisionTree.jl? DecicionTree.jl is a CART (Classification and Regression Tree) package in the Julia machine learning programing language. Various steps like loading data, segregating data into training and testing, and building a model is very easy to implement using this package in Julia. There is no need to transpose data as DecisionTree.jl does not require it. It just takes a two lines statement to build the model providing a few arguments (e.g. depth, minimum number of samples in leaf, minimum number of samples in split etc.) as per user requirement. This package saves lots of time and money for regression and classification problems compared to creating a decision tree ML model from scratch. We used decisionTree.jl for a retail client to build a model to classify potential customer data and were able to achieve near about 70% accuracy, which is considered as very good accuracy. Review collected by and hosted on G2.com. What do you dislike about DecisionTree.jl? There is no issue as such with DecisionTree.jl as it works smoothly for simple to medium complex problems with good accuracy. I have yet to test its performance for complex problems where input data is very diverse, with more than 20 attributes to consider for classification or regression. One small disadvantage for programmers is that DecisionTree.jl package does not assign data type automatically to your loaded data. It seems it does not assign a data type to improve performance. So, you need to write a few more statements to caste data type to your data before building a model. Review collected by and hosted on G2.com. What problems is DecisionTree.jl solving and how is that benefiting you? DecisionTree.jl is a package that helps to build a decision tree or regression tree ML model easily in Julia language. A programmer need not build a model from scratch, which makes them productive and saves client's money. We used this package for a retail user for a small project. It was a rapid implementation and worked successfully for production data. Review collected by and hosted on G2.com. Show More 3/20/2023 Validated ReviewerIncentivizedSource: G2 invite PS Pranav S.
