Cobalt chromium (CoCr) alloys are utilized to make dental prosthesis. Casting CoCr is a common operation in dentistry laboratories due its low cost. surplus (metal remaining the sprue and crucible former) frequently reused by reduce recycle metal waste. However, quality safety of these recast require further information. Microbial attachment surface prostheses may affect safety. Biofilm formati...

We consider the problem of estimation a high-dimensional probability distribution from i.i.d. samples using model classes functions in tree-based tensor formats, particular case networks associated with dimension partition tree. The is assumed to admit density respect product measure, possibly discrete for handling random variables. After discussing representation classical we present learning ...
