A Convex Formulation for Mixed Regression with Two Components: Minimax Optimal Rates
Yudong Chen, Xinyang Yi, Constantine Caramanis
We consider the mixed regression problem with two components, under adversarial and stochastic noise. We give a convex optimization formulation that provably recovers the true solu…
Modeling the Time-varying Subjective Quality of HTTP Video Streams with Rate Adaptations
Chao Chen, Lark Kwon Choi, Gustavo de Veciana +3
Newly developed HTTP-based video streaming technologies enable flexible rate-adaptation under varying channel conditions. Accurately predicting the users' Quality of Experience (Qo…
Delay-Constrained Video Transmission: Quality-driven Resource Allocation and Scheduling
Amin Abdel Khalek, Constantine Caramanis, Robert W. Heath
Real-time video demands quality-of-service (QoS) guarantees such as delay bounds for end-user satisfaction. Furthermore, the tolerable delay varies depending on the use case such a…
Alternating Minimization for Mixed Linear Regression
Xinyang Yi, Constantine Caramanis, Sujay Sanghavi
Mixed linear regression involves the recovery of two (or more) unknown vectors from unlabeled linear measurements; that is, where each sample comes from exactly one of the vectors,…
Distinguishing Infections on Different Graph Topologies
Chris Milling, Constantine Caramanis, Shie Mannor +1
The history of infections and epidemics holds famous examples where understanding, containing and ultimately treating an outbreak began with understanding its mode of spread. Influ…
Resource Optimization in Device-to-Device Cellular Systems Using Time-Frequency Hopping
Qiaoyang Ye, Mazin Al-Shalash, Constantine Caramanis +1
We develop a flexible and accurate framework for device-to-device (D2D) communication in the context of a conventional cellular network, which allows for time-frequency resources t…
