This study introduces Tsallis statistics as a novel error measure for artificial neural networks (ANNs). The Tsallis entropy error function demonstrates effectiveness in handling challenges like class imbalance and noisy data in ANNs.
Area of Science:
- Machine Learning
- Computational Statistics
Background:
- Artificial neural networks (ANNs) are widely used classifiers in diverse fields.
- Various error functions exist to enhance ANN predictive power.
- Tsallis statistics, though successful in other machine learning areas, is underexplored in ANNs.
Purpose of the Study:
- To investigate the q-generalized function based on Tsallis statistics as an alternative error measure for ANNs.
- To evaluate the performance and identify the strengths and weaknesses of this novel error function.
Main Methods:
- Extensive simulations were conducted using an artificial benchmarking dataset.
- The proposed Tsallis entropy error function was implemented and tested within the ANN framework.
Main Results:
- The Tsallis entropy error function shows successful integration into ANNs.
- Satisfactory results were achieved, demonstrating robustness against class imbalance and noisy data.
- The function also proved effective with non-informative predictors.
Conclusions:
- Tsallis entropy error function offers a viable alternative for ANNs.
- It provides a robust performance, particularly in challenging data scenarios.
- Further exploration of Tsallis statistics in machine learning is warranted.

Entropy
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...

The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.

Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
