Compressed Hypothesis Testing: To Mix or Not to Mix?
Myung Cho, Weiyu Xu, Lifeng Lai
In this paper, we study the problem of determining anomalous random variables that have different probability distributions from the rest random variables. Instead of s…
Degraded Broadcast Channel with Secrecy Outside a Bounded Range
Shaofeng Zou, Yingbin Liang, Lifeng Lai +2
The -receiver degraded broadcast channel with secrecy outside a bounded range is studied, in which a transmitter sends messages to receivers, and the channel quality gra…
On Randomized Distributed Coordinate Descent with Quantized Updates
Mostafa El Gamal, Lifeng Lai
In this paper, we study the randomized distributed coordinate descent algorithm with quantized updates. In the literature, the iteration complexity of the randomized distributed co…
Efficient Byzantine Sequential Change Detection
Georgios Fellouris, Erhan Bayraktar, Lifeng Lai
In the multisensor sequential change detection problem, a disruption occurs in an environment monitored by multiple sensors. This disruption induces a change in the observations of…
