Unemployment benefitsUnemployment benefits, also called unemployment insurance, unemployment payment, unemployment compensation, or simply unemployment, are payments made by authorized bodies to unemployed people. In the United States, benefits are funded by a compulsory governmental insurance system, not taxes on individual citizens. Depending on the jurisdiction and the status of the person, those sums may be small, covering only basic needs, or may compensate the lost time proportionally to the previous earned salary.
Variable (mathematics)In mathematics, a variable (from Latin variabilis, "changeable") is a symbol that represents a mathematical object. A variable may represent a number, a vector, a matrix, a function, the argument of a function, a set, or an element of a set. Algebraic computations with variables as if they were explicit numbers solve a range of problems in a single computation. For example, the quadratic formula solves any quadratic equation by substituting the numeric values of the coefficients of that equation for the variables that represent them in the quadratic formula.
Kernel density estimationIn statistics, kernel density estimation (KDE) is the application of kernel smoothing for probability density estimation, i.e., a non-parametric method to estimate the probability density function of a random variable based on kernels as weights. KDE answers a fundamental data smoothing problem where inferences about the population are made, based on a finite data sample. In some fields such as signal processing and econometrics it is also termed the Parzen–Rosenblatt window method, after Emanuel Parzen and Murray Rosenblatt, who are usually credited with independently creating it in its current form.
Crime preventionCrime prevention is the attempt to reduce and deter crime and criminals. It is applied specifically to efforts made by governments to reduce crime, enforce the law, and maintain criminal justice. Criminologists, commissions, and research bodies such as the World Health Organization, United Nations, the United States National Research Council, the UK Audit Commission have analyzed their and others' research on what lowers rates of interpersonal crime.
Hate crimeA hate crime (also known as a bias-motivated crime or bias crime) is a prejudice-motivated crime which occurs when a perpetrator targets a victim because of their membership (or perceived membership) of a certain social group or racial demographic. Examples of such groups can include, and are almost exclusively limited to ethnicity, disability, language, nationality, physical appearance, political views and/or affiliation, age, religion, sex, gender identity, or sexual orientation.
OverfittingIn mathematical modeling, overfitting is "the production of an analysis that corresponds too closely or exactly to a particular set of data, and may therefore fail to fit to additional data or predict future observations reliably". An overfitted model is a mathematical model that contains more parameters than can be justified by the data. In a mathematical sense, these parameters represent the degree of a polynomial. The essence of overfitting is to have unknowingly extracted some of the residual variation (i.
Japanese war crimesThe Empire of Japan committed war crimes and crimes against humanity in many Asian-Pacific countries during the period of Japanese imperialism, primarily during the Second Sino-Japanese and Pacific Wars. These incidents have been described as "the Asian Holocaust". Some war crimes were committed by Japanese military personnel during the late 19th century, but most were committed during the first part of the Shōwa era, the name given to the reign of Emperor Hirohito.
