On Unlimited Sampling
Ayush Bhandari, Felix Krahmer, Ramesh Raskar
Shannon's sampling theorem provides a link between the continuous and the discrete realms stating that bandlimited signals are uniquely determined by its values on a discrete set.…
Accelerating Neural Architecture Search using Performance Prediction
Bowen Baker, Otkrist Gupta, Ramesh Raskar +1
Methods for neural network hyperparameter optimization and meta-modeling are computationally expensive due to the need to train a large number of model configurations. In this pape…
Pairwise Confusion for Fine-Grained Visual Classification
Abhimanyu Dubey, Otkrist Gupta, Pei Guo +3
Fine-Grained Visual Classification (FGVC) datasets contain small sample sizes, along with significant intra-class variation and inter-class similarity. While prior work has address…
Sampling Without Time: Recovering Echoes of Light via Temporal Phase Retrieval
Ayush Bhandari, Aurelien Bourquard, Ramesh Raskar
This paper considers the problem of sampling and reconstruction of a continuous-time sparse signal without assuming the knowledge of the sampling instants or the sampling rate. Thi…
