What are Autoencoders?
Autoencoders are a type of neural network that can learn to compress and reconstruct data. Autoencoders consist of an encoder network that transforms the input data into a latent representation and a decoder network that transforms the latent representation back into the reconstructed data. Autoencoders can be trained using unsupervised learning to learn useful features of the input data or for dimensionality reduction.
What do Autoencoders do?
Autoencoders can learn to compress and reconstruct data by minimizing the difference between the input data and the reconstructed data. The latent representation learned by the encoder can be used to extract useful features from the input data, which can be used for tasks such as image classification, anomaly detection, and image generation.
Some benefits of using Autoencoders
Autoencoders offer several benefits for data compression and feature extraction:
Data compression: Autoencoders can learn to compress data into a lower-dimensional representation, enabling more efficient storage and transmission of the data.
Feature extraction: Autoencoders can learn to extract useful features from the input data, enabling better performance on downstream tasks such as classification and clustering.
Anomaly detection: Autoencoders can be used to detect anomalies in the input data by comparing the reconstructed data to the input data and identifying areas of high reconstruction error.
