Constraint-based optimization and utility elicitation using the minimax decision criterion
In many situations, a set of hard constraints encodes the feasible configurations of some system or product over which multiple users have distinct preferences. However, making su...

Beyond interpolation: optimal reconstruction by quasi-interpolation
We investigate the use of quasi-interpolating approximation schemes, to construct an estimate of an unknown function from its given discrete samples. We show theoretically and wit...

Optimal Diversity Multiplexing Tradeoff Region in Asymmetric Multiple Access Channels
— We consider a multiple access channel (MAC) with multiple antennas, where each user has different diversity and multiplexing gain requirement. For this configuration, we chara...
