Intelligent Modeling of Music Teaching Feedback Using Audio Spectrogram Features and Attention-Weighted Emotional Factors

Overview

HarmoniousMusicFeedback is an intelligent framework for modeling music teaching feedback using audio spectrogram features and attention-weighted emotional factors. The system combines a Harmonious Feedback Network (HFN) with a Harmonious Feedback Integration (HFI) strategy to generate feedback that is both technically accurate and emotionally aware.

HFN employs a multimodal encoder architecture that extracts time–frequency spectrogram features from musical performances and fuses them with emotional attention cues. HFI adds an adaptive refinement layer based on graphical propagation and reinforcement-inspired feedback adjustment, enabling context-aware and progressively improving feedback for learners.

This repository provides a research-oriented reference implementation of the HFN–HFI pipeline, including data preprocessing stubs, model definition, training and evaluation loops, and inference utilities.

Features



Audio spectrogram based technical analysis

Emotion-aware attention weighting over time–frequency regions

Multimodal encoder for acoustic and emotional inputs

Harmonious Feedback Network (HFN) for feature fusion and prediction

Harmonious Feedback Integration (HFI) for adaptive feedback refinement

Multi-objective training for technical accuracy and emotional consistency

Metrics for classification performance and affective alignment


Methodology

Harmonious Feedback Network (HFN)

HFN is a multimodal encoder architecture that:



Converts raw audio into spectrograms using STFT-based processing

Applies convolutional layers to capture local spectral–temporal patterns

Encodes emotional factors as low-dimensional embeddings

Uses attention to reweight spectrogram features according to emotional salience

Produces a shared representation for music teaching feedback prediction


Mathematically, the model works on an attention-weighted spectrogramS(τ, ω) = |X(τ, ω)| · A(τ, ω)where |X(τ, ω)| is the magnitude spectrogram and A(τ, ω) is derived from emotional intensities.

Harmonious Feedback Integration (HFI)

HFI refines feedback predictions through:



A graphical propagation layer that models relationships between feedback dimensions

An adaptive update rule that adjusts feedback vectors based on target and current states

A reinforcement-style reward signal measuring performance improvement across iterations


The integration strategy aims to balance technical precision with emotional coherence while remaining efficient enough for near real-time feedback.

This implementation is dataset-agnostic but follows the structure of three conceptual datasets used in the original study:




Dataset Name

Repository Structure

The core code is intentionally simple and lightweight:

model.py – implementation of HFN and lightweight HFI refinement layer

dataset.py – dataset and dataloader for audio + emotion pairs

utils.py – helper functions, metrics, checkpoint utilities

inference.py – script to run predictions with a trained model


Applications
