Despite recent notable advances of AI-Education research, formal music education is still largely performed as it was at the beginning of the last century. Instrument technical practice especially is still largely performed in a classical setting with little use of modern technologies, possibly due to being a skill-based curriculum. While other researchers have argued for the potential benefits of using Artificial Intelligence for the personalization of music education, it still seems to be rare both in schools and in research. In this paper, we present a systematic literature review exploring the use of computational generation of exercises for personalized music learning, with a special interest in piano. To do so, we retrieve research papers that use AI to improve personalization in music education exploring both what computational methods can provide personalization in music teaching, and how frequently AI is actually used for generation in this context. We screened 360 papers retrieved from online repositories, selecting 40 relevant papers that would satisfy some minimal quality requirements. Analyzing the papers, we found that while there is interest from the scientific community in improving music education through AI and computational means more generally, AI is under-utilized for generation despite its potential for personalization. We found no examples of generation of piano technical exercises, and, more generally, that instrumental technique is indeed the aspect that has seen lesser use of AI enhancement, often limited to adding visualizations to normal instrumental practice.

Today's deep learning architectures are primarily based on perceptron models, which do not capture the oscillatory dynamics characteristic of biological neurons. Although oscillatory systems have recently gained attention for their closer resemblance to neural behavior, they still fall short of modeling the intricate spatio-temporal interactions observed in natural neural circuits. In this paper, we propose a bio-inspired oscillatory state system (BioOSS) designed to emulate the wave-like propagation dynamics critical to neural processing, particularly in the prefrontal cortex (PFC), where complex activity patterns emerge. BioOSS comprises two interacting populations of neurons: p neurons, which represent simplified membrane-potential-like units inspired by pyramidal cells in cortical columns, and o neurons, which govern propagation velocities and modulate the lateral spread of activity. Through local interactions, these neurons produce wave-like propagation patterns. The model incorporates trainable parameters for damping and propagation speed, enabling flexible adaptation to task-specific spatio-temporal structures. We evaluate BioOSS on both synthetic and real-world tasks, demonstrating superior performance and enhanced interpretability compared to alternative architectures.

The Categorical Compositional Distributional (DisCoCat) model has been proven to be very successful in modelling sentence meaning as the interaction of word meanings. Words are modelled as quantum states, interacting guided by grammar. This model of language has been extended to density matrices to account for ambiguity in language. Density matrices describe probability distributions over quantum states, and in this work we relate the mixedness of density matrices to ambiguity in the sentences they represent. The von Neumann entropy and the fidelity are used as measures of this mixedness. Via the process of amplitude encoding, we introduce classical data into quantum machine learning algorithms. First, the findings suggest that in quantum natural language processing, amplitude-encoding data onto a quantum computer can be a useful tool to improve the performance of the quantum machine learning models used. Second, the effect that these encoded data have on the above-introduced relation between entropy and ambiguity is investigated. We conclude that amplitude-encoding classical data in quantum machine learning algorithms makes the relation between the entropy of a density matrix and ambiguity in the sentence modelled by this density matrix much more intuitively interpretable.

Rhythm is an inherent aspect of human behavior, present from infancy and embedded in cultural practices. At the core of rhythm perception lies meter anticipation, a spontaneous process in the human brain that typically occurs before actual beats. This anticipation can be framed as a time series prediction problem. From the perspective of human embodied system behavior, although many models have been developed for time series prediction, most prioritize accuracy over biological realism, contrasting with the natural imprecision of human internal clocks. Neuroscientific evidence, such as infants’ natural meter synchronization, underscores the need for biologically plausible models. Therefore, we propose a neuron oscillator-based dynamic system that simulates human behavior during meter perception. The model introduces two tunable parameters for local and global adjustments, fine-tuning the oscillation combinations to emulate human-like rhythmic behavior. The experiments are conducted under three common scenarios encountered during human-machine interaction, demonstrating that the proposed model can exhibit human-like reactions. Additionally, experiments involving human-machine and interhuman interactions show that the model successfully replicates real-world rhythmic behavior, advancing toward more natural and synchronized human-machine rhythm interaction.

Rhythm is a fundamental aspect of human behaviour, present from infancy and deeply embedded in cultural practices. Rhythm anticipation is a spontaneous cognitive process that typically occurs before the onset of actual beats. While most research in both neuroscience and artificial intelligence has focused on metronome-based rhythm tasks, studies investigating the perception of complex musical rhythm patterns remain limited. To address this gap, we propose a hierarchical oscillator-based model to better understand the perception of complex musical rhythms in biological systems. The model consists of two types of coupled neurons that generate oscillations, with different layers tuned to respond to distinct perception levels. We evaluate the model using several representative rhythm patterns spanning the upper, middle, and lower bounds of human musical perception. Our findings demonstrate that, while maintaining a high degree of synchronization accuracy, the model exhibits human-like rhythmic behaviours. Additionally, the beta band neuronal activity in the model mirrors patterns observed in the human brain, further validating the biological plausibility of the approach.

Auditory working memory is essential for various daily activities, such as language acquisition, conversation. It involves the temporary storage and manipulation of information that is no longer present in the environment. While extensively studied in neuroscience and cognitive science, research on its modeling within neural networks remains limited. To address this gap, we propose a general framework based on a close-loop predictive coding paradigm to perform short auditory signal memory tasks. The framework is evaluated on two widely used benchmark datasets for environmental sound and speech, demonstrating high semantic similarity across both datasets.
