Top Hit Ratios for Multi-Classification Models

Description

Calculate and plot a multi-class model's predictions accuracy based on top N predictions and distribution of probabilities.

Usage

mplot_topcats(tag, score, multis, model_name = NA)

Arguments

tag	Vector. Real known label.
score	Vector. Predicted value or model's result.
multis	Data.frame. Containing columns with each category probability or score (only used when more than 2 categories coexist).
model_name	Character. Model's name

Value

Plot with performance results over most frequent categories.
