WebSep 1, 2024 · Hamming code Explaining the algorithm is easier with an example. Let’s take the earlier 7-bit data 1001101that Alice wanted to send to Bob again and run through how Hamming code works. WebHamming distance is the simplest edit distance algorithm for string alignment. It tells us the edit distance between two strings if we're only allowed to make substitutions - no insertions or deletions. We will consider the Hamming distance to be defined only if the two strings are the same lengths.

WebWorking with Spatial Data. Spatial data refers to data that is represented in a geometric space. E.g. points on a coordinate system. We deal with spatial data problems on many tasks. E.g. finding if a point is inside a boundary or not. SciPy provides us with the module scipy.spatial, which has functions for working with spatial data.
