LoadCsv Method will throw bad_alloc exception if the file given as parameter is not found.
I was wondering if this library includes the accelerated version of the HDBSCAN algo from 2017?

The implementation in Python: https://github.com/scikit-learn-contrib/hdbscan
Hello everybody,
Can someone, please, explain to me a small quicksort implementation detail in the UndirectedGraph
class.
In the method selectPivotIndex
there is an early return block
if (startIndex - endIndex <= 1)
return startIndex;
It seems that this condition is always true. That's totally fine for the quicksort implementation as the pivot could be any element in between startIndex
and endIndex
, though the heuristic after this block would be obsolete. Is it correct?
My dataset is 50000 x 22 dimensions. When running HDBSCAN on it, the following error occurs:
terminate called after throwing an instance of 'std::length_error'
what(): cannot create std::vector larger than max_size()
Aborted (core dumped)
vector.resize() throws bad_alloc allow when it is used to resize greater than 16,000 points
hello,
Could you please explain the difference between parameters minClusterSize and minPoints?
thanks,
Omer.
