WebI have extensive experience in predictive and descriptive analytics, and I am well versed in Python, R, PySpark, SQL, and Base SAS. Worked on … A decision tree is a decision support tool that uses a tree-like model of decisions and their possible consequences, including chance event outcomes, resource costs, and utility. It is one way to display an algorithm that only contains conditional control statements. Decision trees are commonly used in operations … See more A decision tree is a flowchart-like structure in which each internal node represents a "test" on an attribute (e.g. whether a coin flip comes up heads or tails), each branch represents the outcome of the test, and each leaf node … See more Decision-tree elements Drawn from left to right, a decision tree has only burst nodes (splitting paths) but no sink nodes (converging paths). So used manually they can grow very big and are then often hard to draw fully by hand. Traditionally, … See more Among decision support tools, decision trees (and influence diagrams) have several advantages. Decision trees: • Are simple to understand and interpret. People are able to understand decision tree models after a brief explanation. • Have value even with … See more • Behavior tree (artificial intelligence, robotics and control) • Boosting (machine learning) • Decision cycle See more Decision trees can also be seen as generative models of induction rules from empirical data. An optimal decision tree is then defined as a tree that accounts for most of the data, while minimizing the number of levels (or "questions"). Several algorithms to … See more A few things should be considered when improving the accuracy of the decision tree classifier. The following are some possible optimizations to consider when looking to make … See more It is important to know the measurements used to evaluate decision trees. The main metrics used are accuracy, sensitivity, specificity, precision, miss rate, false discovery rate, … See more

WebDecision trees are used for classification, and regression trees are used for parameter estimation. Such algorithms can perform well when there is increased complexity and nonlinearity between dependent and independent variables. The random forest is the most popular tree-based learning algorithm, introduced by Breiman (2001). A random forest ...
