Fourier Representations for Black-Box Optimization over Categorical Variables
Hamid Dadkhahi, Jesus Rios, Karthikeyan Shanmugam +1
Optimization of real-world black-box functions defined over purely categorical variables is an active area of research. In particular, optimization and design of biological sequenc…
Combinatorial Black-Box Optimization with Expert Advice
Hamid Dadkhahi, Karthikeyan Shanmugam, Jesus Rios +4
We consider the problem of black-box function optimization over the boolean hypercube. Despite the vast literature on black-box function optimization over continuous domains, not m…
Alternating Linear Bandits for Online Matrix-Factorization Recommendation
Hamid Dadkhahi, Sahand Negahban
We consider the problem of online collaborative filtering in the online setting, where items are recommended to the users over time. At each time step, the user (selected by the en…
Learning Tree-Structured Detection Cascades for Heterogeneous Networks of Embedded Devices
Hamid Dadkhahi, Benjamin M. Marlin
In this paper, we present a new approach to learning cascaded classifiers for use in computing environments that involve networks of heterogeneous and resource-constrained, low-pow…
Learning Shallow Detection Cascades for Wearable Sensor-Based Mobile Health Applications
Hamid Dadkhahi, Nazir Saleheen, Santosh Kumar +1
The field of mobile health aims to leverage recent advances in wearable on-body sensing technology and smart phone computing capabilities to develop systems that can monitor health…
Masking Strategies for Image Manifolds
Hamid Dadkhahi, Marco F. Duarte
We consider the problem of selecting an optimal mask for an image manifold, i.e., choosing a subset of the pixels of the image that preserves the manifold's geometric structure pre…
