Difference between Loss function and Statistics

Loss function vs. Statistics

In mathematical optimization, statistics, econometrics, decision theory, machine learning and computational neuroscience, a loss function or cost function is a function that maps an event or values of one or more variables onto a real number intuitively representing some "cost" associated with the event. Statistics is a branch of mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data.

Similarities between Loss function and Statistics

Loss function and Statistics have 21 things in common (in Unionpedia): Actuarial science, Bayesian probability, Decision theory, Design of experiments, Differentiable function, Econometrics, Estimation theory, Expected value, Frequentist inference, Independent and identically distributed random variables, Least squares, Linear regression, Machine learning, Mean, Mean squared error, Regression analysis, Statistic, Statistical classification, Statistical population, Student's t-test, Variance.

Actuarial science

Actuarial science is the discipline that applies mathematical and statistical methods to assess risk in insurance, finance and other industries and professions.

Bayesian probability

Bayesian probability is an interpretation of the concept of probability, in which, instead of frequency or propensity of some phenomenon, probability is interpreted as reasonable expectation representing a state of knowledge or as quantification of a personal belief.

Decision theory

Decision theory (or the theory of choice) is the study of the reasoning underlying an agent's choices.

Design of experiments

The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe or explain the variation of information under conditions that are hypothesized to reflect the variation.

Differentiable function

In calculus (a branch of mathematics), a differentiable function of one real variable is a function whose derivative exists at each point in its domain.

Econometrics

Econometrics is the application of statistical methods to economic data and is described as the branch of economics that aims to give empirical content to economic relations.

Estimation theory

Estimation theory is a branch of statistics that deals with estimating the values of parameters based on measured empirical data that has a random component.

Expected value

In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents.

Frequentist inference

Frequentist inference is a type of statistical inference that draws conclusions from sample data by emphasizing the frequency or proportion of the data.

Independent and identically distributed random variables

In probability theory and statistics, a sequence or other collection of random variables is independent and identically distributed (i.i.d. or iid or IID) if each random variable has the same probability distribution as the others and all are mutually independent.

Least squares

The method of least squares is a standard approach in regression analysis to approximate the solution of overdetermined systems, i.e., sets of equations in which there are more equations than unknowns.

Linear regression

In statistics, linear regression is a linear approach to modelling the relationship between a scalar response (or dependent variable) and one or more explanatory variables (or independent variables).

Machine learning

Machine learning is a subset of artificial intelligence in the field of computer science that often uses statistical techniques to give computers the ability to "learn" (i.e., progressively improve performance on a specific task) with data, without being explicitly programmed.

Mean

In mathematics, mean has several different definitions depending on the context.

Mean squared error

In statistics, the mean squared error (MSE) or mean squared deviation (MSD) of an estimator (of a procedure for estimating an unobserved quantity) measures the average of the squares of the errors—that is, the average squared difference between the estimated values and what is estimated.

Regression analysis

In statistical modeling, regression analysis is a set of statistical processes for estimating the relationships among variables.

Statistic

A statistic (singular) or sample statistic is a single measure of some attribute of a sample (e.g. its arithmetic mean value).

Statistical classification

In machine learning and statistics, classification is the problem of identifying to which of a set of categories (sub-populations) a new observation belongs, on the basis of a training set of data containing observations (or instances) whose category membership is known.

Statistical population

In statistics, a population is a set of similar items or events which is of interest for some question or experiment.

Student's t-test

The t-test is any statistical hypothesis test in which the test statistic follows a Student's ''t''-distribution under the null hypothesis.

Variance

In probability theory and statistics, variance is the expectation of the squared deviation of a random variable from its mean.

Loss function and Statistics Comparison

Loss function has 80 relations, while Statistics has 267. As they have in common 21, the Jaccard index is 6.05% = 21 / (80 + 267).
