Outlier-resilient model fitting via percentile losses: Methods for general and convex residuals
João Domingos, João Xavier
We consider the problem of robustly fitting a model to data that includes outliers by formulating a percentile optimization problem. This problem is non-smooth and non-convex, henc…

Robust Target Localization in 2D: A Value-at-Risk Approach
João Domingos, João Xavier
This paper consider considers the problem of locating a two dimensional target from range-measurements containing outliers. Assuming that the number of outlier is known, we formula…

Graph Fourier Transform: A Stable Approximation
João Domingos, José M. F. Moura
In Graph Signal Processing (GSP), data dependencies are represented by a graph whose nodes label the data and the edges capture dependencies among nodes. The graph is represented b…
