Chebyshev’s inequality

"In probability theory, Chebyshev’s inequality (also called the Bienaymé–Chebyshev inequality) guarantees that, for a wide class of probability distributions, no more than a certain fraction of values can be more than a certain distance from the mean.

Specifically, no more than 1/k2 of the distribution’s values can be more than k standard deviations away from the mean

(or equivalently, at least 1 − 1/k2 of the distribution’s values are within k standard deviations of the mean).

The inequality has great utility because it can be applied to any probability distribution in which the mean and variance are defined. "

https://en.wikipedia.org/wiki/Chebyshev%27s_inequality

"Probabilistic statement[edit]

Let X (integrable) be a random variable with finite expected value μ and finite non-zero variance σ2. Then for any real number k > 0,

{\displaystyle \Pr(|X-\mu |\geq k\sigma )\leq {\frac {1}{k^{2}}}.}\Pr(|X-\mu |\geq k\sigma )\leq {\frac {1}{k^{2}}}.

Only the case {\displaystyle k>1}k > 1 is useful. When {\displaystyle k\leq 1}{\displaystyle k\leq 1} the right-hand side {\displaystyle {\frac {1}{k^{2}}}\geq 1}{\displaystyle {\frac {1}{k^{2}}}\geq 1} and the inequality is trivial as all probabilities are ≤ 1."

"As an example, using {\displaystyle k={\sqrt {2}}} shows that the probability that values lie outside the interval {\displaystyle (\mu -{\sqrt {2}}\sigma ,\mu +{\sqrt {2}}\sigma )} does not exceed {\frac {1}{2}}."

"Markov’s inequality

"Markov’s inequality (and other similar inequalities) relate probabilities to expectations, and provide (frequently loose but still useful) bounds for the cumulative distribution function of a random variable."

Statement[edit]

If X is a nonnegative random variable and a > 0, then the probability that X is at least a is at most the expectation of X divided by a:[1]

{\displaystyle \operatorname {P} (X\geq a)\leq {\frac {\operatorname {E} (X)}{a}}.}{\displaystyle \operatorname {P} (X\geq a)\leq {\frac {\operatorname {E} (X)}{a}}.}

Overview on optimization concepts: From the Internet

Optimization Concepts:

Convex sets:
"A convex set is a set of points such that, given any two points A, B in that set, the line AB joining them lies entirely within that set. Intuitively, this means that the set is connected (so that you can pass between any two points without leaving the set) and has no dents in its perimeter.
Convexity/What is a convex set? – Wikibooks, open books for …
https://en.wikibooks.org › wiki › Convexity › What_is_a_convex_set?"

Convex functions:
"A convex function is a real-valued function defined on an interval with the property that its epigraph (the set of points on or above the graph of the function) is a convex set. Convex minimization is a subfield of optimization that studies the problem of minimizing convex functions over convex sets.
Convex set – Wikipedia

Basics of convex analysis:
https://en.wikipedia.org/wiki/Convex_analysis
A good overview: http://eceweb.ucsd.edu/~gert/ECE273/CvxOptTutPaper.pdf

least-squares:
"The least squares method is a statistical procedure to find the best fit for a set of data points by minimizing the sum of the offsets or residuals of points from the plotted curve. Least squares regression is used to predict the behavior of dependent variables.Sep 2, 2019
Least Squares Method Definition – Investopedia
https://www.investopedia.com › terms › least-squares-method"

"minimizing the sum of the squares of the residuals made in the results of every single equation."
"The most important application is in data fitting. The best fit in the least-squares sense minimizes the sum of squared residuals (a residual being: the difference between an observed value, and the fitted value provided by a model)."
"Least-squares problems fall into two categories: linear or ordinary least squares and nonlinear least squares, depending on whether or not the residuals are linear in all unknowns. The linear least-squares problem occurs in statistical regression analysis; it has a closed-form solution. The nonlinear problem is usually solved by iterative refinement; at each iteration the system is approximated by a linear one, and thus the core calculation is similar in both cases.

Polynomial least squares describes the variance in a prediction of the dependent variable as a function of the independent variable and the deviations from the fitted curve.

When the observations come from an exponential family and mild conditions are satisfied, least-squares estimates and maximum-likelihood estimates are identical.[1] The method of least squares can also be derived as a method of moments estimator.

The following discussion is mostly presented in terms of linear functions but the use of least squares is valid and practical for more general families of functions. Also, by iteratively applying local quadratic approximation to the likelihood (through the Fisher information), the least-squares method may be used to fit a generalized linear model."
https://en.wikipedia.org/wiki/Least_squares

linear and quadratic programs:
"A linear programming (LP) problem is one in which the objective and all of the constraints are linear functions of the decision variables."
"A quadratic programming (QP) problem has an objective which is a quadratic function of the decision variables, and constraints which are all linear functions of the variables."
"LP problems are usually solved via the Simplex method. "
"An alternative to the Simplex method, called the Interior Point or Newton-Barrier method, was developed by Karmarkar in 1984. Also in the last decade, this method has been dramatically enhanced with advanced linear algebra methods so that it is often competitive with the Simplex method, especially on very large problems."
"Since a QP problem is a special case of a smooth nonlinear problem, it can be solved by a smooth nonlinear optimization method such as the GRG or SQP method. However, a faster and more reliable way to solve a QP problem is to use an extension of the Simplex method or an extension of the Interior Point or Barrier method."

Quadratic programming
https://optimization.mccormick.northwestern.edu/index.php/Quadratic_programming

semidefinite programming:
"Semidefinite programming – Wikipedia
https://en.wikipedia.org › wiki › Semidefinite_programming
Semidefinite programming (SDP) is a subfield of convex optimization concerned with the optimization of a linear objective function (a user-specified function that the user wants to minimize or maximize) over the intersection of the cone of positive semidefinite matrices with an affine space, i.e., a spectrahedron.
‎Motivation and definition · ‎Duality theory · ‎Examples · ‎Algorithms"

"Semidefinite Programming
https://web.stanford.edu › ~boyd › papers › sdp
In semidefinite programming we minimize a linear function subject to the constraint that an affine combination of symmetric matrices is positive semidefinite. Such a constraint is nonlinear and nonsmooth, but convex, so positive definite programs are convex optimization problems."

https://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-251j-introduction-to-mathematical-programming-fall-2009/readings/MIT6_251JF09_SDP.pdf

minimax:

"Minimax – Wikipedia
https://en.wikipedia.org › wiki › Minimax
Minimax (sometimes MinMax, MM or saddle point) is a decision rule used in artificial intelligence, decision theory, game theory, statistics and philosophy for minimizing the possible loss for a worst case (maximum loss) scenario. When dealing with gains, it is referred to as "maximin"—to maximize the minimum gain.""

duality theory:
"In mathematical optimization theory, duality or the duality principle is the principle that optimization problems may be viewed from either of two perspectives, the primal problem or the dual problem. The solution to the dual problem provides a lower bound to the solution of the primal (minimization) problem.
Duality (optimization) – Wikipedia
https://en.wikipedia.org › wiki › Duality_(optimization)"
"Usually the term "dual problem" refers to the Lagrangian dual problem but other dual problems are used – for example, the Wolfe dual problem and the Fenchel dual problem. The Lagrangian dual problem is obtained by forming the Lagrangian of a minimization problem by using nonnegative Lagrange multipliers to add the constraints to the objective function, and then solving for the primal variable values that minimize the original objective function. This solution gives the primal variables as functions of the Lagrange multipliers, which are called dual variables, so that the new problem is to maximize the objective function with respect to the dual variables under the derived constraints on the dual variables (including at least the nonnegativity constraints)."

theorems of alternative:
"Farkas’ lemma belongs to a class of statements called "theorems of the alternative": a theorem stating that exactly one of two systems has a solution.
Farkas’ lemma – Wikipedia
https://en.wikipedia.org › wiki › Farkas’_lemma"

"In layman’s terms, a Theorem of the Alternative is a theorem which states that given two conditions, one of the two conditions is true. It further states that if one of those conditions fails to be true, then the other condition must be true.May 8, 1991"
http://digitalcommons.iwu.edu/cgi/viewcontent.cgi?article=1000&context=math_honproj

theorems of alternative applications; : https://link.springer.com/article/10.1007/BF00939083

interior-point methods:
"Interior-point methods (also referred to as barrier methods or IPMs) are a certain class of algorithms that solve linear and nonlinear convex optimization problems.""
https://en.wikipedia.org/wiki/Interior-point_method

Applications of signal processing:
"Applications of DSP include audio signal processing, audio compression, digital image processing, video compression, speech processing, speech recognition, digital communications, digital synthesizers, radar, sonar, financial signal processing, seismology and biomedicine.
Digital signal processing – Wikipedia
https://en.wikipedia.org › wiki › Digital_signal_processing"

Applications of optimization to signal processing:
"Convex optimization has been used in signal processing for a long time, to choose coefficients for use in fast (linear) algorithms, such as in filter or array design; more recently, it has been used to carry out (nonlinear) processing on the signal itself."

Digital and analog circuit design:
"With the advent of logic synthesis, one of the biggest challenges faced by the electronic design automation (EDA) industry was to find the best netlist representation of the given design description. While two-level logic optimization had long existed in the form of the Quine–McCluskey algorithm, later followed by the Espresso heuristic logic minimizer, the rapidly improving chip densities, and the wide adoption of HDLs for circuit description, formalized the logic optimization domain as it exists today." https://en.wikipedia.org/wiki/Logic_optimization
