CNNs for Face Detection and Recognition

development of object classification, localization and detec-tion techniques. 2.1. Sliding Window In the early development of face detection, researchers tended to treat it as a repetitive task of object classifica-tion, by imposing sliding windows and performing object classification with the neural networks on the window re-gion.

Unsupervised Deep Embedding for Clustering Analysis

Several variants of k-means have been proposed to address issues with higher-dimensional input spaces.De la Torre & Kanade(2006);Ye et al.(2008) perform joint dimension-ality reduction and clustering by first clustering the data with k-means and then projecting the data into a lower di-mensions where the inter-cluster variance is maximized.
