We have solved the problem statement in two phases. In the first phase, we used a 3D CNN model to reduce high-dimensional input into latent space and decode it into an original image to represent the input in rich feature space. In the second phase, we utilized this model to reduce input into rich features and used these features to train standard machine learning models for predicting hearing thresholds. We have experimented with autoencoders and variational autoencoders in the first phase for dimensionality reduction and explored random forest, XGBoost and multilayer perceptron for regressing the thresholds. We split the given data set into training and testing sets and achieved an 8.80 range and 22.57 range for PT500 and PT4000 on the test set, respectively. We got the lowest RMSE using multi-layer perceptron among the other models.  \nOur approach leverages the unique capabilities of VAEs to capture complex, non-linear relationships within highdimensional neuroimaging data. We rigorously evaluated the models using various metrics, focusing on the root mean squared error (RMSE). The results highlight the efficacy of the multi-layer neural network model, which outperformed other techniques in terms of accuracy. This project advances the application of data mining in medical diagnostics and enhances our understanding of age-related hearing loss through innovative machine-learning frameworks.  \n1. Introduction  \nAge-related hearing loss (ARHL), also known as presbycusis, is an increasingly prevalent condition that affects a significant portion of the aging population. Characterized by the gradual loss of hearing capabilities, ARHL poses substantial challenges to interpersonal communication and overall quality of life. Traditional methods of diagnosing and evaluating ARHL rely on auditory tests and essential medical imaging; however, these methods often fall short of identifying the underlying neuroanatomical changes associated with the condition.  \nRecent medical imaging and machine learning advancements present new opportunities to enhance our under-  \nstanding of ARHL. Specifically, brain magnetic resonance imaging (MRI) offers detailed insights into the brain’s structural integrity. At the same time, sophisticated data mining techniques enable the analysis of complex datasets to reveal patterns not immediately apparent to human observers. This project leverages these technologies to bridge the gap between neuroanatomical changes and auditory function, employing a dataset that combines gray matter images with auditory threshold measurements.  \nOur research employs advanced machine learning techniques, including variational autoencoders (VAEs) and multi-layer neural networks, to analyze the relationship between brain structure and hearing loss. These models are particularly suited for this task because they can handle high-dimensional data and learn deep representations that capture the subtle nuances of brain morphology related to ARHL. By training these models on a robust dataset from clinical settings, this project aims to predict hearing thresholds more accurately and identify specific brain regions that correlate with hearing decline.  \nThrough this approach, the project seeks to contribute to the broader field of medical diagnostics by providing a m","cbCaimuYe8anT36F","https://ap.wps.com/l/cbCaimuYe8anT36F","pdf",959963,1,5,"English","en",105,"# Introduction\n# Literature Review\n# Methodology\n## Data Acquisition\n## Data Preparation","[{\"question\":\"What two phases does the project use to predict hearing loss thresholds?\",\"answer\":\"The first phase learns and compresses 3D gray-matter images into latent representations using autoencoders/VAEs, then decodes them to rich feature space.
