<p>Hi Haifeng,</p>

<p>I'm not 100% sure what you mean.  If you are looking for the LSH code, you can find it here:<br>
<a href="https://github.com/mlpack/mlpack/tree/master/src/mlpack/methods/lsh">https://github.com/mlpack/mlpack/tree/master/src/mlpack/methods/lsh</a></p>

<p>I suppose maybe you could use LSH to hash your points into different buckets, and then extract the buckets themselves?</p>

<p>If you're looking for a different algorithm to do high-dimensional clustering, all I can suggest is possibly k-means; I think that's the only technique mlpack has implemented that would be useful in your case.</p>

<p>I hope this helps... please let me know if I can clarify anything.</p>
