- algorithm - Peak signal detection in realtime timeseries data - Stack . . .
Robust peak detection algorithm (using z-scores) I came up with an algorithm that works very well for these types of datasets It is based on the principle of dispersion: if a new datapoint is a given x number of standard deviations away from a moving mean, the algorithm gives a signal The algorithm is very robust because it constructs a separate moving mean and deviation, such that previous
- algorithm - Finding all possible combinations of numbers to reach a . . .
How would you go about testing all possible combinations of additions from a given set N of numbers so they add up to a given final number? A brief example: Set of numbers to add: N = {1,5,22,15,0
- The best shortest path algorithm - Stack Overflow
What is the difference between the "Floyd-Warshall algorithm" and "Dijkstra's Algorithm", and which is the best for finding the shortest path in a graph? I need to calculate the shortest path betw
- algorithm - Calculate distance between two latitude-longitude points . . .
How do I calculate the distance between two points specified by latitude and longitude? For clarification, I'd like the distance in kilometers; the points use the WGS84 system and I'd like to unde
- algorithm - What does O (log n) mean exactly? - Stack Overflow
A common algorithm with O (log n) time complexity is Binary Search whose recursive relation is T (n 2) + O (1) i e at every subsequent level of the tree you divide problem into half and do constant amount of additional work
- What is the fastest integer factorization algorithm?
The algorithm picks on a number A along the curve, then looks up the safe distance and jumps to the next hashtable, or at least the algorithm does those factor checks until the next hashtable becomes available Given enough hashtables, I'm thinking we can pretty much avoid most of the checking Notes on lookup tables
- c - Fast CRC algorithm? - Stack Overflow
CRC32 algorithm is exactly what I'm looking for, but I can't use it because the table it requires is way too huge (it is for an embedded system where resources are VERY rare) So: any suggestions for a fast and slim CRC algorithm? It does not matter when collisions are a bit more probable than with the original CRC32
- Finding the median of an unsorted array - Stack Overflow
There is still no linear algorithm in existence AFAIK for finding the median of an arbitrary, unsorted dataset Think about it - a dataset that contains values 1 25 has true median 13 If one of its MoM n 5 subsets is [13,14,15,16,17], the median of that subset is 15 (and 13 falls out of contention)
