	Inner product space - Wikipedia, the free encyclopedia
		In mathematics, an inner product space is a vector space with additional structure, an inner product, scalar product or dot product, which allows us to introduce geometrical notions such as angles and lengths of vectors.
		Inner product spaces are generalizations of Euclidean space (with the dot product as the inner product) and are studied in functional analysis.
		An orthonormal basis for an inner product space V is an orthonormal sequence whose algebraic span is V.

		Inner product spaces are generalizations of Euclidean space (where the dot product instantiates the inner product) and are studied in functional analysis.
		An example of a metrically incomplete inner product space is the space C[a, b] of continuous complex valued functions on the interval [a,b].

		In mathematics, an inner product space is a vector space with additional structure, an inner product, scalar product or dot product, which allows us to talk about angles and lengths of vectors.
		Inner product spaces are generalizations of Euclidean space (where the dot product takes the place of the inner product) and are studied in functional analysis.
		Formally, an inner product space is a real or complex vector space V together with a map f : V x V → F where F is the ground field (either R or C).

		The article on Hilbert space has several examples of inner product spaces where the metric induced by the inner product yields a complete metric spaces.
		An example of an inner product which induces an incomplete metric is the space C[a, b] of continuous complex valued functions on the interval [a,b].
		Finally the fact that the sequence has a dense algebraic span, in the inner product norm, follows from the fact that the sequence has a dense algebraic span, this time in the space of continuous periodic functions on [[-pi,pi]] with the uniform norm.

		The inner product of a function with itself is the norm.
		The Schwarz inequality in quantum mechanics is analogous to dot products and cosines in Euclidean space.
		In a similar fashion, it is hoped that because the product of a transpose of a quaternion with a quaternion has the properties of a complete inner product space, the power of the mathematical field of quaternions can be used to solve a wide range of problems in quantum mechanics.

		Inner Product Spaces We have seen that linear vector spaces provide a useful framework for describing a broad range of classes of signals, both discrete-time and continuous-time.
		However, optimization and signal approximation are still problematic in many normed linear spaces, as, in general, the solution may not be unique and it may be difficult to find the solution(s).
		In a complex linear space S an inner product assigns a complex number to any pair of elements {x,y} ∈S.

	The Gram-Schmidt Algorithm - HMC Calculus Tutorial
		To obtain an orthonormal basis for an inner product space V, use the Gram-Schmidt algorithm to construct an orthogonal basis.
		For more abstract spaces, however, the existence of an orthonormal basis is not obvious.
		The Gram-Schmidt algorithm is powerful in that it not only guarantees the existence of an orthonormal basis for any inner product space, but actually gives the construction of such a basis.

	The Inner Product
		The inner product (or ``dot product'', or ``scalar product'') is an operation on two vectors which produces a scalar.
		Defining an inner product for a Banach space specializes it to a Hilbert space (or ``inner product space'').
		The complex conjugation of the second vector is done in order that a norm will be induced by the inner product:

		In connection with two-label classification tasks over the Boolean domain, we study the question whether the class of decision functions induced by a given Bayesian network can be represented within a low-dimensional inner product space.
		For Bayesian networks with an explicitly given (full or reduced) parameter collection, we establish tight bounds on the dimension of the ``natural'' inner product space.
		Further, we consider a variant of the logistic autoregressive Bayesian network and show that every sufficiently expressive inner product space must have dimension at least $2^{\Omega(n)}$, where $n$ is the number of network nodes.

		In connection with two-label classification tasks over the Boolean domain, we consider the possibility to combine the key advantages of Bayesian networks and of kernel-based learning systems. This leads us to the basic question whether the class of decision functions induced by a given Bayesian network can be represented within a low-dimensional inner product space.
		For Bayesian networks with an explicitly given (full or reduced) parameter collection, we show that the ``natural'' inner product space has the smallest possible dimension up to factor $2$ (even up to an additive term $1$ in many cases).
		For a slight modification of the so-called logistic autoregressive Bayesian network with $n$ nodes, we show that every sufficiently expressive inner product space has dimension at least $2^{n/4}$.
