“…Also, SVM achieves high classification rate compare to Decision Trees and C4.5 classification techniques. Although there exist many tree-based methods e.g., [7,8,11,12,13], for applications with memory constraints, hashing based ANN techniques have attracted more attention. The ANN techniques have constant query time and also substantially reduced storage as they usually store only compact binary codes for each point in X.…”

“…Hash function Universality Suppose U is a universe of keys, and Gj H is a family of a finite collection of hash functions [12] We define the following objective function measuring the empirical accuracy on the labeled data for a family of hash functions H (5) So the general algorithm can be described as: 1. Extract local features from every image 2. compute distances of the query to all training examples using LSH with the objective function as in (5)and pick the nearest neighbors; 3.…”

“…Certain common genome sequences are often queried more times than the rest [22]. (2) Similarly, earthquake detection or satellite image data, both high-dimensional data [6,28], often query certain similar regions of the space that are of more interest. These queries can be viewed as part of a query workload.…”

“…While the LSH family (explained further in Section 3) in [14] was originally defined for the Hamming distance, it was later defined for other distance measures such as the Euclidean distance [9]. Effective Variants of LSH: LSH has been shown to be useful in various domains such as biomedical sciences [5,7,22], geological sciences [6,28], etc. Several works were subsequently proposed [4,10,11,13,15,16,24,26] to improve upon the original work.…”
