What is dot product?Question:What is dot product?Vectors:A vector is a quantity having magnitude and direction as well. The examples of vector quantities are velocity, acceleration, displacement, etc. While a scalar quantity has magnitude only. The examples of scalar quantities are speed, distance...
in terms of the directions they point. The measure is a scalar number (single value) that can be used to compare the two vectors and to understand the impact of repositioning one or both of them. The dot product is obtained by performing mathematical calculations on the vector properties...
What is the angle between the vectors A and B if vector A multiplied by vector B = 0.5 AB ? Three vectors are given as A = 3i - 4j + 6k, B = 4i + 5j - 6k, and C = -i + 2j + 3k. What is the dot product of A and B and the cross product of B and C?
This article explores vector databases and embeddings, their use cases, and how they work. It also explains the key differences between vector and graph databases and offers a brief overview of popular solutions: Pinecone, Chroma, Milvus, Weaviate, and Qdrant. What is a vector database and vec...
Vectors are typically designated in boldface (e.g., vectoraand vectorb). The magnitude of a vector is indicated by a vertical bar on each side of the vector, like this: |a|. Types of vectors There are various types of vectors, including: ...

A vectoris a one-dimensional (orfirst-degreeorfirst-order) tensor, containing multiple scalars of the same type of data. For example, the weather model might represent the low, mean and high temperatures of that single day in vector form as(25, 30, 33). Each scalar component is afeature...
