My problem initial features
are x , y ,theta that normalized in range[0,255].
For each object
number of features is variable
.
Clustering is applied so each cluster has number of features & each object belongs to multiple clusters
.
In the predict stage ,compute clusters for each object from initial features(new features
).
Each object belongs to a maximum of 10 clusters
.
Total number of clusters is 4000
.
If we consider new features constant
for each object we have 4000 dimension that
it very large for classify
.Only 10 features may be useful and my features is sparse.
My question :
Is there any way that we can classify these sparse features
with best performance & which classifier is useful for it?
Note:I use locality sensitive hashing for classify new features with 4000 dimension that is very slow.
