Stacking Ensemble Method for Brain Tumor Classification: Performance Analysis

Towards AI

4] Dataset The dataset comes from Kaggle [5], which contains a database of 3206 brain MRI images. The three weak learner models used for this implementation were k-nearest neighbors, decision trees, and naive Bayes. For the meta-model, k-nearest neighbors were used again.

Five machine learning types to know

IBM Journey to AI blog

Classification algorithms include logistic regression, k-nearest neighbors and support vector machines (SVMs), among others. Naïve Bayes algorithms include decision trees , which can actually accommodate both regression and classification algorithms.

Structured data refers to neatly organised data that fits into tables, such as spreadsheets or databases, where each column represents a feature and each row represents an instance. For example, linear regression is typically used to predict continuous variables, while decision trees are great for classification and regression tasks.

K-Nearest Neighbor Regression Neural Network (KNN) The k-nearest neighbor (k-NN) algorithm is one of the most popular non-parametric approaches used for classification, and it has been extended to regression. Decision Trees ML-based decision trees are used to classify items (products) in the database.

Key Components of Data Science Data Science consists of several key components that work together to extract meaningful insights from data: Data Collection: This involves gathering relevant data from various sources, such as databases, APIs, and web scraping. Data Cleaning: Raw data often contains errors, inconsistencies, and missing values.

Decision trees are more prone to overfitting. Some algorithms that have low bias are Decision Trees, SVM, etc. The K-Nearest Neighbor Algorithm is a good example of an algorithm with low bias and high variance. So, this is how we draw a typical decision tree. Let us see some examples.
