# Deep Autoencoding Gaussian Mixture Model for Unsupervised Anomaly Detection
In this paper, we propose Deep Autoencoding Gaussian Mixture Model (DAGMM), a deep learning framework that addresses the aforementioned challenges in unsupervised anomaly detection from several aspects.
- aforementioned adj.上述的；前面提及的
Usually, it is hard to learn deep autoencoders by end-to-end training, as they can be easily stuck in less attractive local optima, so pre-training is widely adopted.
- be easily stuck in less attractive local optima：陷入不那么吸引人的局部最优状态
It is hard to make any significant change to a well-trained autoencoder via fine-tuning.
Given a dataset of N samples, the objective function that guides DAGMM training is constructed as follows.
