Maximum Volume Subset Selection for Anchored Boxes
unpublished
Preserved Fulltext
We study the problem of selecting k boxes in B that maximize the volume of the union of the selected boxes. ...
The research is motivated by applications in skyline queries for databases and in multicriteria optimization, where the problem is known as the hypervolume subset selection problem. ...

Using data from different residue subsets, we interpolate pMHCII mutant binding affinities by Gaussian process (GP) regression of residue volume and hydrophobicity. ...
Our work finds that prediction is most accurate for neutral residues at anchor residue sites without register shift. This work holds relevance to predicting pMHCII binding and accelerating ASI design. ...
