I’m exploring the use of autoencoders for dimensionality reduction in machine learning. Can anyone explain the techniques involved in using autoencoders for this purpose? What are some practical applications where autoencoders excel in reducing data dimensions effectively? Any insights, resources, or case studies would be greatly appreciated.

I suggest considering other methods that are not based on deep learning. There’s so much more to explore beyond PCA, like ISOMAP, diffusion maps, and other related techniques. I find that this approach offers more power than PCA and requires less tuning compared to autoencoders.
Autoencoders are a deep learning method used to reduce data dimensions. They work by learning a simpler version of the input data. The model is designed to copy the input to the output while compressing data in the middle layers, helping to keep only the most important features.
