An Introduction to the WEKA Data Mining System - CCSU

• K-nearest neighbor (KNN, IBk) Take the class of the nearest neighbor or the majority class among K neighbors K=1 -> no K=3 -> no K=5 -> yes K=14 -> yes (Majority predictor, ZeroR) • Distance is calculated as the number of different attribute values • Euclidean distance for numeric attributes • Weighted K-nearest neighbor K=5 -> undecided

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.

DetCo: Unsupervised Contrastive Learning for Object Detection

learning and online clustering, e.g. MoCo v1/v2 [19,5], BYOL [18], and SwAV [3], have achieved great progress to bridge the performance gap between unsupervised and fully-supervised methods for image classification. How-ever, their transferring ability on object detection is not sat-isfactory. Concurrent to our work, recently DenseCL [39],
