QUESTION
My objective is the following: given a list of numbers (int. or float) (1D), I need to find N amount of numbers that are closest to
each other in this list. For example:
Given sample_list = [1, 8, 14, 15, 17, 100, 35] and N = 3, the desired function should return a list of [14, 15, 17], because the 3 "nearest neighbors" in this list are 14, 15, and 17.
So far, I have tackled the problem the following way, being forced to make several compromises in my approach (after unsuccessfully searching for a solution online):
I decided to iterate over each number in the list and find its N amount of "nearest neighbors". These "nearest neighbors" are stored in a new list and then compared with other such lists using numpy.diff function. The list with the smallest amount resulted from numpy.diff is the winner.
At the base of my solution is the code provided by this article on geeksforgeeks.org. The idea to use numpy.diff function came from here on stackoverflow.com

I have two kind of data, one is dataframe and one is right now many lists contain data regard hours of image aqcuisition, so the data look like this:
the pandas dataframe (has dates and hours from 23/6 -04/07, everyday from 07:00-17:00):
...ANSWER
Answered 2020-Oct-19 at 17:04Your list of times isn't an ideal format, so I'll show you the approach for one date, where the dataframe h23 is manually built. You could code this to build out a dataframe that holds all of the times if you want.
The basic premise is to make a dataframe h23 for example, with all of the timestamps of the photos. Use this to merge with the df timestamp, using pd.merge_asof which has the ability to do the closest time match. nearest means the actual time could be before of after, but there are options for backward and forward as well if the time needs to be the nearest time before the event.
QUESTION
This is similar to Find closest GeoJSON polygon to point when point lies outside of all polygons in Elasticsearch but instead of returning the closest polygon, I'd like to return all documents that has a polygon closer than a particular distance (say 10 km). I'd like the distance to each polygon to be included in the result and it should be sorted by distance (ascending or descending doesn't matter).
A comment in the referred question pointed to a github issue that has now been resolved (since Elastic Search 7.7) but I cannot seem to figure out how to do it based on the documentation.
Update
After reading the answer by joe I want to clarify that by "distance" I mean the closest distance to the nearest point of the polygon's border. Like what's described in this question for PostGIS.
...ANSWER
Answered 2020-Jun-29 at 17:19You could use a geo_shape query with a buffered circle which will act as an umbrella that your polygons-of-interest will intersect. If they do, they match.
The only issue is that the "distance to each polygon" is somewhat arbitrary -- are we talking about the nearest point of a polygon's border? Or maybe its center?
I've only been able to come up with an implementation of the latter but it requires a secondary center field since scripted center computation would be too onerous.
Here's a visual:

QUESTION
I have two Tables.
Table1 goes from A1:F10 and shows the machine assignment.
Table2 goes from G1:K10 and shows the storage for the machines.
With a button I want to simulate which storage should be used for which machine.
In column C stands the date when the machine has to be built. In Column I stands the date when the storage is ready to use.
For example: The first machine has to start on 08/15/2018. How can I check which date in Column I is the closest to 08/15/2018?
This is my code so far:
...ANSWER
Answered 2018-Aug-06 at 03:06With your example, im assuming you want
- Start = 15.06.2018, Ende = 14.03.2018
- Start = 25.08.2018, Ende = 26.07.2018
Add this Function and call it like YourCell.Value = getClosestDateBefore(StartCell.Value, Range("I2:I9"))
QUESTION
I have a (sorted) set of unsigned int's. I need to find the closest element to a given number.
I am looking for a solution using the standard library,
my first solution was to use binary search, but STL's implementation only returns if the element exists.
This post, Find Closest Element in a Set, was helpful and I implemented a solution based on std::lower_bound method,
(*Assuming the set has more than 2 elements, no empty/boundary checks are made):
...ANSWER
Answered 2019-Nov-20 at 09:36You could use std::min_element() : as a comperator, give it a lambda that returns the absulute diff e.g.
QUESTION
I have a list of DayOfWeek enum item: var daysOfWeek = List
This list contains a variable amount of DaysOfWeek items, e.g. Monday, Thursday, Saturday.
I would like to find the next DateTime to any given DateTime based on List.
If the given date would fall on a Wednesday, the next DateTime which should return would be a Thursday.
If the given date would fall on a Thursday, the next DateTime which should return would be a Saturday.
So far, I have been fiddling around with the some LINQ expressions and trying some options with the Min() extension method but have no code which I could share that would be workable. I am wondering if I am missing some real basic LINQ functionality.
SO-Topics that have given me some ideas so far include this one and that one, however I was not able to produce a solution for my problem with their answers.

QUESTION
I have two sets of points, one is a map consisting of x,y coordinates, and the second is a path of x,y coordinates. I'm trying to find the closest map points to my path points, pretty simple. Except my map is 380000 points and my paths (of which I have several) each consist of ~ 350000 points themselves. Other than sampling my data to get smaller datasets, I'm trying to find a faster way to accomplish this task.
base algorithm: ...ANSWER
Answered 2018-Apr-05 at 09:21The following is a mini example of what you're trying to do. Considers the variable coords1 as your variable log['point'] and coords2 as your variable log['point']. The end result is the index of the coord2 closest to coord1.
