On Distributional Assumptions and Whitened Cosine Similarities

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2008
Recently, an interpretation of the whitened cosine similarity measure as a Bayes decision rule was proposed (C. Liu, "The Bayes Decision Rule Induced Similarity Measures,'' IEEE Trans. Pattern Analysis and Machine Intelligence, vol. 29, no. 6, pp. 1086-1090, June 2007. This communication makes the observation that some of the distributional assumptions

An Efficient Similarity Join Algorithm with Cosine Similarity Predicate

2010
Given a large collection of objects, finding all pairs of similar objects, namely similarity join, is widely used to solve various problems in many application domains.Computation time of similarity join is critical issue, since similarity join requires computing similarity values for all possible pairs of objects.

Quasi Cosine Similarity Metric Learning

2015
It is vital to select an appropriate distance metric for many learning algorithm. Cosine distance is an efficient metric for measuring the similarity of descriptors in classification task. However, the cosine similarity metric learning (CSML) [3] is not widely used due to the complexity of its formulation and time consuming.

Scalable spectral clustering with cosine similarity

2018 24th International Conference on Pattern Recognition (ICPR), 2018
We propose a unified scalable computing framework for three versions of spectral clustering - Normalized Cut (Shi and Malik, 2000), the Ng-Jordan-Weiss (NJW) algorithm (2001), and Diffusion Maps (Coifman and Lafon, 2006), in the setting of cosine similarity.

Query-Directed Probing LSH for Cosine Similarity

Proceedings of the Fifth International Conference on Network, Communication and Computing, 2016
Locality-sensitive hashing (LSH) considered as an efficient algorithm for large-scale similarity search has become increasingly popular. Recently, many of its variants have been applied widely in high-dimensional similarity search. To overcome the drawback of requirement for a large number of hash tables, researchers proposed the famous Multi-Probe LSH

Online and Batch Learning of Generalized Cosine Similarities

2009 Ninth IEEE International Conference on Data Mining, 2009
In this paper, we define an online algorithm to learn the generalized cosine similarity measures for kNN classification and hence a similarity matrix A corresponding to a bilinear form. In contrary to the standard cosine measure, the normalization is itself dependent on the similarity matrix which makes it impossible to use directly the algorithms ...

The Cosine Similarity Technique for Removing the Redundancy Sample

2019 22nd International Symposium on Wireless Personal Multimedia Communications (WPMC), 2019
The k-nearest neighbor algorithm is one of the basic and simple classification algorithms that share a common limitation of the algorithm which requires more computation cost when the size of training data is enlarged. To solve this problem, a new method applied to the cosine similarity for reducing the size of the training data set is proposed.

Improving Document Similarity Calculation Using Cosine-Similarity Graphs

2019
Data mining information using various indices and determining candidates that can be judged as having the same tendency based on similarity between documents is common. The accuracy of similarity largely depends on a sufficient amount of data and requires advanced analysis using natural language processing.

Sentiment analysis using cosine similarity measure

2015 IEEE 2nd International Conference on Recent Trends in Information Systems (ReTIS), 2015
The opinion of other people is often a major factor influencing our decisions. For a consumer it affects purchase decisions and for a producer or a service provider it helps in making business decisions. Companies spend a lot of money and time on surveys for gathering the public opinion on products and services.

Cosine Similarity Metric Learning for Face Verification

2011
Face verification is the task of deciding by analyzing face images, whether a person is who he/she claims to be. This is very challenging due to image variations in lighting, pose, facial expression, and age. The task boils down to computing the distance between two face vectors. As such, appropriate distance metrics are essential for face verification
