body: <p>How to calculate the near neigbours for high-dimensional data(especially for 15000 dims data)?</p>
  
  <p>----I was confirmed that euclidean distance is not an efficient way to represent the distance between high dimensional datas. Are there any better ideas to calculate the distance for high-dim data?</p>
