This post gives an overview of our deep learning based technique for performing unsupervised clustering by leveraging semi-supervised models. An unlabeled dataset is taken and a subset of the dataset is labeled using pseudo-labels generated in a completely unsupervised way. The pseudo-labeled dataset combined with the complete unlabeled data is used to train a semi-supervised model.

Virtual adversarial training has been used for:

  1. Improving supervised learning performance
  2. Semi-supervised learning
  3. Deep unsupervised clustering

There are several regularization techniques which prevent overfitting and help the model generalize better for unseen examples. Regularization helps the model parameters to be less dependent on the training data. The two most commonly used regularization techniques are Dropout and L1/L2 regularization.

In L1/L2…

This post gives an overview of various deep learning based clustering techniques. I will be explaining the latest advances in unsupervised clustering which achieve state-of-the-art performance by leveraging deep learning.

This is a re-post of the original article:

Unsupervised learning is an active field of research and has always been a challenge in deep learning. Finding out meaningful patterns from large datasets without the presence of labels is extremely helpful for many applications. Advances in unsupervised learning are very crucial for artificial general intelligence. Performing unsupervised clustering is equivalent to building a classifier without using labeled samples.
