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 ... Webb18 juni 2024 · Hi everyone, I’m looking for clarification as to why we use the dot product as a “similarity” metric for two vectors with collaborative filtering. For example, imagine two users, both with a metric of 0.5. The dot product will be 0.25. They have the same “similarity” rank as two users with values of 0.25 and 1, which are quite far apart.
