Binary trees - Study guides, Revision notes & Summaries

Data point - Observation/record of (perhaps multiple) measurements for a single member of a population or data set. In the standard tabular format, a row of data. Bayesian Information criterion (BIC) - Model selection technique that trades off model fit and model complexity. When comparing models, the model with lower BIC is preferred. Generally penalizes complexity more than AIC. 1-norm (rectilinear distance, Manhattan distance) - Think of distances in blocks E (|xi - yi|) 2-norm (euclide...

Three main categories of predictive modeling problems - Answer- 1. Descriptive - Focuses on what happened in the past and aims to "describe" or explain the observed trends by identifying the relationships between different variables 2. Predictive - Focuses on what will happen in the future and is concerned with making accurate predictions 3. Prescriptive - Uses a combination of optimization and simulation to investigate and quantify the impact of different prescribed actions in different sce...

COSC-Computer Science Fundamental Concepts Study guide Core Concept #1 - Algorithms and Data Structures - correct answer A data structure is an arrangement of data in a computer's memory or even disk storage. An example of several common data structures are arrays, linked lists, queues, stacks, binary trees, and hash tables. An algorithm is a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer. 1.1 - Big O Notation - co...

True or false: In a regression tree, every leaf of the tree has a different regression model that might use different attributes, have different coefficients, etc. - correct answer True - Each leaf's individual model is tailored to the subset of data points that follow all of the branches leading to the leaf. True or false: Tree-based approaches can be used for other models besides regression. - correct answer True - For example, a classification tree might have a different SVM or KNN ...

D Which statement describes a queue data structure? A.) It is a sequence of elements in which insertion and deletion takes place at one end. B.) It is a sequence of elements in which insertion and deletion takes place at both ends. C.) It is a sequence of elements in which insertion can take place anywhere in the sequence and deletion takes place only at the front. D.) It is a sequence of elements in which insertions can take place only at the back end and deletions can take place only at...
