I am trying to ray trace the Stanford bunny model which is PLY format. I have a parser which parses the PLY file and gives me the value of co-ordinates of triangles and also their vertices. Now I am c
I am trying to make some Haskell types which are parametrized not by types but by elements of a type, specifically, integers.For instance, a (linear-algebra) vector in R^2 and a vector in R^3 are diff
I am designing an automated trading software for the foreign exchange market. In a MYSQL database I have years of market data at five-minute intervals. I have 4 different metrics for this data alongs
What is the difference between these two开发者_StackOverflow algorithms?cKDTree is a subset of KDTree, implemented in C++ wrapped in Cython, so therefore faster.
I need to know if this algorithm is a known one: void getMatches(IpVec &ipts1, IpVec &ipts2, IpPairVec &matches, float ratio) {
Hello Does anybody has iterative implementation of Kd-Tree in C++. I tried but it is failing when the number of nodes are odd.
Please anyone tell me how to construct dual kd-tree and how to traverse it? And at least tell me the algorithm for finding nearest neighbor using this 开发者_开发技巧dual tree concept in java. This w
I am trying to utilize k-nearest neighbors for the string similarity problem i.e. given a string and a knowledge base, I want to output k st开发者_开发问答rings that are similar to my given string. Ar
I am trying to solve the k nearest neighbor problem on a 开发者_JAVA百科set of objects in 3-space.These objects live in a MongoDB collection with all the joy and sorrow that comes with document based
Is anyone aware of a KD-Tree, or similar spatial index, implemented in SQL? I was considering writing my own using Python and Django\'s ORM, but I\'d like to avoid reinventing the wheel.
