I want to calculate a large distance matrix, based on a higher dimensional vector. For instance, I have 1000 instances each represented by 20 vectors of length 10. The distance between each two instances is given by the mean distance between each of the 20 vectors associated to each vector. So I want to go fr…

Do you know how to input the object from the same class in python?
I am python beginner. I have to define a method distanceFromOther() that takes the different dot as a factor and returns the distance between itself and the other point. Class Point is for treating points (x,y) in a two-dimensional plane as objects. This is the code that I made. I made two objects a and b. I …
Edit Distance w/ operational weights in Python
I am learning about edit distance for the first time and have only been coding for a few months. I’m trying to modify the algorithm such that the different editing operations carry different weights as follows: insertion weighs 20, deletion weighs 20 and replacement weighs 5. I have been able to impleme…

Calculate Density based on Lat/Lon
I’m very sorry to say that I do not have any sample code for this question. The reason being, I’ve been looking for a way to do this and I’ve got no ideas. I’m not looking for specific code help, more like some general guidance on where to start. I have lat/lon for people living around…
grid with circular distances python
I have a 2d grid of dim q(rows) p(columns). The element of the grid are the indices of the element itself. So the element a[i,j]=(i,j). Now I need to create pair-wise distances between these points with circularity constraint, meaning that the element distance(a[i,p-1],a[i,0])=1 (I am using 0-index based matr…
How to add the name of the nearest point?
I have two data frames with coordinates of attractions and exists. I use this to get the distance to the nearest exit: I want to add a column with the name of this nearest exit. It has to look like: I will be grateful for any help! Answer Write this line at the end of for loop
Calculating EMD for 3D point-clouds is very SLOW
I wanted to calculate the distance between two 3D point clouds with at least 2000 points using Earth Mover’s Distance with the following code, however, it is too slow and does not work properly. So, is there any way to calculate it for approximate it faster? Answer As of SciPy 1.4.0 (released December 2…
Distance Matrix between rows of a Pandas Dataframe with Lat and Lon
I have a Pandas DataFrame with the coordinates of different cell towers where one column is the Latitude and another column is the Longitude like this: and so on I need to get the distances between each cell tower and all the others, and subsequently between each cell tower and its closest neighbouring tower.…
How do I find the difference between two values without knowing which is larger?
I was wondering if there was a function built into Python that can determine the distance between two rational numbers but without me telling it which number is larger. e.g. Obviously I could write a simple definition to calculate which is larger and then just do a simple subtraction: but I’d rather not…
