Special Issue Information

Dear Colleagues,

The process of learning is the ability to remember, retrieve, organize, or associate a pattern of features to generate a body of knowledge. This natural ability inspired an artificial counterpart, named machine learning (ML), which induces rules from a set of data and performs tasks automatically. Some examples of ML tools are neural networks, genetic algorithms, or Bayesian models, which can store or classify samples of patterns. Such patterns can be data series from geology, economy, sociology, physics, biomedicine, astronomy, or weather, for instance, machine learning can help to predict future behavior or to fulfill a local lack of knowledge.

Machine learning models, besides being inspired by natural processes, use concept from statistical physics, specifically entropy. The second law of thermodynamics states that an isolated system evolves spontaneously to form an equilibrium with maximal entropy. This macroscopical definition of entropy can be microscopically understood as a measure of disorder or uncertainty of a large system and has precise formulation in the scope of information theory. Both machine learning and entropy information have a common background pertaining to how a dynamics system relaxes over time to a stationary state, which optimizes its probability, i.e., increases the possible combinations of microstates.

These properties can be used to model a set of patterns of features or predict new patterns that were not presented during the learning process.

The submissions to this Special Issue are expected to contribute to the approaches of machine learning from the viewpoint of information theory. It aims to be a place where researchers share their work on entropy concepts to solve problems in supervised or clustering learning, and investigators on machine learning use information theory to evaluate the accuracy or to develop a dynamical acceleration of the process.

We seek submissions on the interplay between entropy and ML and include the following topics:

  • Mutual information measures for machine learning modeling and prediction.
  • Entropy-based methods for preprocessing highly structured data.
  • Entropy-based ML for predicting data from engineering, medicine, socio-economy, etc.
  • Complexity information of hybrid neural network architectures.

With the rapid development of AI technology, AI painting tools are increasingly used in art creation. However, the effects of works created by different users using AI painting tools vary. Finding out the factors that affect the level of art creation after users use AI painting tools is a matter of concern. To solve this problem, this paper proposes a new Multi-Classification Attention Support Vector Machine (MCASVM) with cross-entropy loss function. By identifying and predicting the level of creativity of ordinary users after using AI painting tools, this model compares and analyzes the influencing factors behind the high and low effects of artistic creativity enhancement after using AI painting tools. The main contribution of this paper is to establish the Art Creation Ability Assessment Dataset (ACAAD) through real data collection to provide data support for subsequent assessments. Meanwhile, MCASVM directly handles the multi-classification problem in the established dataset by introducing multiple SVMs. Among other things, the probabilistic calibration network adjusts the model output so that its predicted probabilities are closer to the probability that the sample truly belongs to the classification. DBAM enhances the feature fusion capability of the model by explicitly focusing on the important channel and spatial features, and it enables the model to more accurately recognize and differentiate between changes in the creative abilities of different users before and after using AI painting tools. The experimental results show that the artistic creativity of ordinary users can be enhanced by AI painting tools, where the most central influencing factors are interest level and social support.

Groove, a complex aspect of music perception, plays a crucial role in eliciting emotional and physical responses from listeners. However, accurately quantifying and predicting groove remains challenging due to its intricate acoustic features. To address this, we propose a novel framework for groove rating that integrates Convolutional Neural Networks (CNNs) with Temporal Convolutional Networks (TCNs), enhanced by entropy regularization and entropy-pooling techniques. Our approach processes audio files into Mel-spectrograms, which are analyzed by a CNN for feature extraction and by a TCN to capture long-range temporal dependencies, enabling precise groove-level prediction. Experimental results show that our CNN–TCN framework significantly outperforms benchmark methods in predictive accuracy. The integration of entropy pooling and regularization is critical, with their omission leading to notable reductions in R2 values. Our method also surpasses the performance of CNN and other machine-learning models, including long short-term memory (LSTM) networks and support vector machine (SVM) variants. This study establishes a strong foundation for the automated assessment of musical groove, with potential applications in music education, therapy, and composition. Future research will focus on expanding the dataset, enhancing model generalization, and exploring additional machine-learning techniques to further elucidate the factors influencing groove perception.
