Some definitions
Definition : What is an algorithm ?
An algorithm is a set of mathematical instructions that must be followed in a fixed order, and that, especially if given to a computer, will help to calculate an answer to a mathematical problem. This is the case in mathematical approaches, but algorithms can also be found in non-mathematical approaches.
Algorithms are largely developed and used in many cases, as for example weather forecast or video games.
Definition : What is a feature variable ?
The variable that is calculated from the field measurements on the animal which are captured by sensor signals, image or sound information
Definition : What is a field data ?
A lot of numbers originating from the sensors (e.g. 240 samples per second for an accelerometer), images (e.g. 25 images per second) or sound signals (e.g. 20,000 samples per second).
Definition : What is a target variable ?
The target variable directly relates to the final objective of the algorithm.
In the example of an infection monitoring system, this means that the variable is a Yes/No status as to whether an animal is infected or not.
Definition : What is a Gold Standard ?
State of the art scientific method to measure or score the status of the target variable
