Using Dot Product as a Measure of Similarity - James D. McCaffrey

Webb28 mars 2024 · Details: The dot product is a specific type of “inner product” function. If the dot product of two vectors is 0, the two vectors are orthogonal (perpendicular) — sort of an intermediate similarity. The length of v = (a, b, c) is sqrt (a^2 + b^2 + c^2). If you normalize two vectors by dividing each by its length, the dot product function ...
