Project Description
This project focuses on the application of Neural Networks for building a robust autoencoder model designed to perform dimensionality reduction and image denoising on the MNIST dataset. Through this model, a compressed representation of input data is generated, reducing noise and reconstructing high-quality outputs. The project employed advanced machine learning techniques, including deep learning frameworks like TensorFlow and Keras, utilizing dense layers to progressively encode and decode data. The model was trained with various encoding dimensions to optimize performance and minimize validation loss.
I used statistical analysis to track and assess the effectiveness of different encoding dimensions, applying binary cross-entropy loss functions and Adam optimization to fine-tune the model’s weights. The iterative process of hyperparameter tuning was a critical component in achieving optimal results. A 3D data visualization approach was employed to illustrate the relationships between encoded representations, highlighting the effectiveness of non-linear dimensionality reduction for pattern recognition in high-dimensional data.
The project demonstrated a comprehensive integration of data analytics, machine learning, and statistical analysis skills, resulting in a model capable of predicting and mitigating data noise, making it highly applicable for real-world business scenarios, especially in industries reliant on image processing and data compression.
