In armandvalsesia/FoodC5: C5.0 classifier for Food Items Mapping

FoodC5

R package to derive probability that any two food items are the same

Overview

FoodC5 is an R package providing an interface to a pre-trained C5.0 classification model. This C5.0 tree enables to predict whether any two food items are the same. It requires the following input parameters:

• fuzzy score: similary between the two food names
• information on how much the two items differ in energy content

The fuzzy score can be computed with with the Foodmapping R package. The difference in energy content can be expressed as 100 * abs( itemA_energy_content - itemB_energy_content ) / itemA_energy_content.

Installation

To install, run the following commands in R:

install.packages("devtools")
devtools::install_github("armandvalsesia/FoodC5", build_vignettes = TRUE)

Quick Start

require("FoodC5")

# load example dataset
data(food_score)

# Compute probability based on a comparison using the English-translated food names
preds <- c5_one_language(food_score,  'ENG_SCORE', 'EDIFF')


# Compute probability based on a comparison using the original food names
# this model is trained for the following languages: English, Dutch, Danish, and a modest subset for Greek, Spanish and Bulgarian.  
preds <- c5_one_language(food_score,  'ENG_SCORE', 'EDIFF', c5_object = read_c50_ori())
