We view strings as sets of characters or as functions from [1..N] to [1..M] to study classical occupancy problems and their application to fundamental hashing algorithms. Functions from [1..N] to [1..N] are mappings, which have an interesting and intricate structure that we can study ...
Big O notation describes the upper bound on the growth rate of an algorithm’s runtime. It provides a way to classify algorithms based on their worst-case performance. For example, an algorithm with a time complexity of O(n) has a linear growth rate, meaning its runtime increases linearly...
Distance and similarity are key concepts in thecontextof cluster analysis. Most algorithms, particularly those yielding hierarchical partitions, start with a distance-or-similarity matrix. The cell entries of this matrix are distances or similarities between pairs of objects. There are many types of ...
Numerical analysis, area of mathematics and computer science that creates, analyzes, and implements algorithms for obtaining numerical solutions to problems involving continuous variables. Such problems arise throughout the natural sciences, social scien
Data is all around us, and every day it becomes increasingly important. Different types of data define more and more of our interactions with the world around us—from using the internet to buying a car, to the algorithms behind news feeds we see, and much more. ...

1b). For individual SV algorithms, we estimated precision to be in the range 80–95% for samples in the 63-sample pilot dataset. Fig. 1: Validation of variant-calling pipelines in PCAWG. a, Scatter plot of estimated sensitivity and precision for somatic SNVs across individual algorithms ...
we don't question them any further," said Theresa Kushner, partner at Business Data Leadership, a data consulting company. "However, if the results don't confirm our hypotheses, we go out of our way to reevaluate the process, the data or the algorithms, thinking we must ...
At each iteration, the kmeans algorithm (see Algorithms) reassigns points among clusters to decrease the sum of point-to-centroid distances, and then recomputes cluster centroids for the new cluster assignments. Notice that the total sum of distances and the number of reassignments decrease at ...
