Triplet loss and its sampling strategies
In my post a year ago, I did discuss about a deep learning technique called DeepRanking. Its core is the triplet loss, which helps to minimize the distance between images in the same group and maximize the ones from different categories . At the moment, I’m working in a project...

Mixture Models in Clustering
In the most recent post, I talked about some famous clustering algorithms and they work well in reality. However, we the data scientists don’t really like these methods because of one thing: they are deterministic and nothing in data science have that deterministic, especially in unsupervised learning: we don’t have...

Clustering and Retrieval (Part 2)
In this blog, I will dive deeper into the techniques of clustering. Clustering or segmentation has wide applications, particularly in RecSys, when you can have the insight about users’s preferences given their activities. For examples, assuming that we have a list of articles that user A reads everyday, we can...
