Big Data Analysis Algorithms Domain algorithm development and engineering In many of the domains, efficient algorithms will be essential in order to obtain the required efficiency. Thus to a large extent, algorithms work in the domains will focus on engineering algorithms, that is, on using efficient algorithms technology in real applications.

Weka algorithm A series of repeatable steps for carrying out a certain type of task with data. As with data structures, people studying computer science learn about different algorithms and their suitability for various tasks.

Specific data structures often play a role in how certain algorithms get implemented. AngularJS is popular with data scientists as a way to show the results of their analysis. As the cost of computing resources dropped, the focus moved more toward statistical analysis of large amounts of data to drive decision making that gives the appearance of Development of data processing algorithm for.

See also machine learningdata mining backpropagation Also, backprop. An algorithm for iteratively adjusting the weights used in a neural network system.

Backpropagation is often used to implement gradient descent. An equation for calculating the probability that something is true if something potentially related to it is true.

The theorem also makes it easier to update a probability based on new data, which makes it valuable in the many applications where data continues to accumulate. Named for eighteenth-century English statistician and Presbyterian minister Thomas Bayes.

See also Bayesian networkprior distribution Bayesian network Also, Bayes net. These graphs aid in performing reasoning or decision making in the face of uncertainty.

Variance is the tendency to learn random things irrespective of the real signal Simultaneously avoiding both requires learning a perfect classifier, and short of knowing it in advance there is no single technique that will always do best no free lunch.

A key driver of this new ability has been easier distribution of storage and processing across networks of inexpensive commodity hardware using technology such as Hadoop instead of requiring larger, more powerful individual computers.

The work done with these large amounts of data often draws on data science skills. This is a discrete probability distribution, as opposed to continuous—for example, instead of graphing it with a line, you would use a histogram, because the potential outcomes are a discrete set of values.

As the number of trials represented by a binomial distribution goes up, if the probability of success remains constant, the histogram bars will get thinner, and it will look more and more like a graph of normal distribution.

See also normal distribution and Wikipedia on the chi-squared test and on chi-squared distribution. Deciding whether an email message is spam or not classifies it among two categories, and analysis of data about movies might lead to classification of them among several genres.

See also supervised learningclustering clustering Any unsupervised algorithm for dividing up data instances into groups—not a predetermined set of groups, which would make this classification, but groups identified by the execution of the algorithm because of similarities that it found among the instances.

See also correlation computational linguistics Also, natural language processing, NLP. A branch of computer science for parsing text of spoken languages for example, English or Mandarin to convert it to structured data that you can use to drive program logic.

Early efforts focused on translating one language to another or accepting complete sentences as queries to databases; modern efforts often analyze documents and other data for example, tweets to extract potentially valuable information.

See also GATEUIMA confidence interval A range specified around an estimate to indicate margin of error, combined with a probability that a value will fall in that range.

The field of statistics offers specific mathematical formulas to calculate confidence intervals. For example, if you can express age or size with a decimal number, then they are continuous variables. In a graph, the value of a continuous variable is usually expressed as a line plotted by a function.

The correlation coefficient is a measure of how closely the two data sets correlate. A correlation coefficient of 1 is a perfect correlation.

This value can also be negative, as when the incidence of a disease goes down when vaccinations go up. A correlation coefficient of -1 is a perfect negative correlation. Always remember, though, that correlation does not imply causation. The training set is given to the algorithm, along with the correct answers The algorithm is then asked to make predictions for each item in the test set.

The answers it gives are compared to the correct answers, and an overall score for how well the algorithm did is calculated.

D3 is popular with data scientists as a way to present the results of their analysis. They run ETL software, marry data sets, enrich and clean all that data that companies have been storing for years. While this sounds like much of what data science is about, popular use of the term is much older, dating back at least to the s.

See also data engineermachine learning data structure A particular arrangement of units of data such as an array or a tree. People studying computer science learn about different data structures and their suitability for various tasks. See also algorithm data wrangling Also, data munging.

The conversion of data, often through the use of scripting languages, to make it easier to work with. Discussions of data science often bemoan the high percentage of time that practitioners must spend doing data wrangling; the discussions then recommend the hiring of data engineers to address this.This document specifies XML syntax and processing rules for creating and representing digital signatures.
