The meaning of VECTOR SPACE is a set of vectors along with operations of addition and multiplication such that the set is a commutative group under addition, it includes a multiplicative inverse, and multiplication by scalars is both associative and dist

The meaning of VECTOR is a quantity that has magnitude and direction and that is commonly represented by a directed line segment whose length represents the magnitude and whose orientation in space represents the direction; broadly : an element of a vect
Each word embedding (i.e. distributed representation of a word) is a real-valued vector in the Euclidean space that corresponds to the “meaning” of the word (Kobayashi et al., 2015). The word vectors are averaged or concatenated to predict the next word in a context (Wang et al., ...
A vector space, or sometimes linear space, V, over a field F, is an abelian group, written additively, with a map F× V→ V such that, for x,y∈V,α,β∈F, 1. αx+y=αx+αy (“linearity”), 2. α+βx=αx+βx, 3. (αβ)x = α(βx), and 4. 1x = x. A ve...
For a function f (x, y), the gradient of f is a vector operator f = [df/x f/y]. The GPU has hardware support for taking gradients of variables in pixel shader programs via the ddx() and ddy() functions. We define the signed distance function to the screen-space curve f (x,...
In this survey we look at the use of vector space models to describe the meaning of words and phrases: the phenomena that vector space models address, and the techniques that they use to do so. Many word meaning phenomena can be described in terms of semantic similarity: synonymy, priming,...
A vector embedding is, at its core, the ability to represent a piece of data as a mathematical equation.Google’s definition of a vector embeddingis“a way of representing data as points in n-dimensional space so that similar data points cluster together.” ...
The best models are well-trained on the types of data they're representing. You can evaluate existing models such as Azure OpenAI text-embedding-ada-002, bring your own model that's trained directly on the problem space, or fine-tune a general-purpose model. Azure AI Search doesn't ...
These vectors, representing data in numerous dimensions, can be thought of as arrows pointing in a particular direction and magnitude in space. As the digital age propels us into an era dominated by AI and machine learning, vector databases have emerged as indispensable tools for storing, ...
