How can we visually determine the class to which a new point belongs using the scatter plot?

Monday, 07 August 2023 by EITCA Academy

In the field of machine learning, one popular algorithm for classification tasks is the K nearest neighbors (KNN) algorithm. This algorithm classifies new data points based on their proximity to existing data points in a training dataset. One way to visually determine the class to which a new point belongs using a scatter plot is

Why is it important to include the dates on the axes when creating a graph to visualize forecasted data in regression forecasting and predicting?

Monday, 07 August 2023 by EITCA Academy

When creating a graph to visualize forecasted data in regression forecasting and predicting, it is important to include the dates on the axes. This practice holds significant importance as it provides a temporal context to the data being presented, facilitating a comprehensive understanding of the trends, patterns, and relationships between variables over time. By incorporating
