Convex piecewise-linear fitting

- A. Magnani, Stephen P. Boyd
- Mathematics
- 1 March 2009

We consider the problem of fitting a convex piecewise-linear function, with some specified form, to given multi-dimensional data. Except for a few special cases, this problem is hard to solve… Expand

Optimal kernel selection in Kernel Fisher discriminant analysis

- Seung-Jean Kim, A. Magnani, Stephen P. Boyd
- Mathematics, Computer Science
- ICML '06
- 25 June 2006

In Kernel Fisher discriminant analysis (KFDA), we carry out Fisher linear discriminant analysis in a high dimensional feature space defined implicitly by a kernel. The performance of KFDA depends on… Expand

Robust Fisher Discriminant Analysis

- 5 December 2005

Fisher linear discriminant analysis (LDA) can be sensitive to the problem data. Robust Fisher LDA can systematically alleviate the sensitivity problem by explicitly incorporating a model of data… Expand

Is a picture worth a thousand words? A Deep Multi-Modal Fusion Architecture for Product Classification in e-commerce

- T. Zahavy, A. Magnani, Abhinandan Krishnan, Shie Mannor
- Computer Science
- AAAI
- 29 November 2016

Classifying products into categories precisely and efficiently is a major challenge in modern e-commerce. The high traffic of new products uploaded daily and the dynamic nature of the categories… Expand

Tractable fitting with convex polynomials via sum-of-squares

- A. Magnani, S. Lall, S. Boyd
- Mathematics
- Proceedings of the 44th IEEE Conference on…
- 12 December 2005

We consider the problem of fitting given data (u<inf>1</inf>,y<inf>1</inf>),...,(u<inf>m</inf>,y<inf>m</inf>) where u<inf>i</inf>∈ R<sup>n</sup>and y<inf>i</inf>∈ R with a convex polynomial f. A… Expand

Robust Beamforming via Worst-Case SINR Maximization

- Seung-Jean Kim, A. Magnani, A. Mutapcic, Stephen P. Boyd, Z. Luo
- Mathematics, Computer Science
- IEEE Transactions on Signal Processing
- 1 April 2008

Minimum variance beamforming, which uses a weight vector that maximizes the signal-to-interference-plus-noise ratio (SINR), is often sensitive to estimation error and uncertainty in the parameters,… Expand

Self-mixing vibrometer with real-time digital signal elaboration.

- A. Magnani, A. Pesatori, M. Norgia
- Medicine, Physics
- Applied optics
- 20 July 2012

This work describes the development of an optical sensor for measurement of vibration without contact. The realized vibrometer is based on real-time digital elaboration of the signal obtained by a… Expand

Self-Organized, Scalable GPS-Free Localization of Wireless Sensors

- A. Magnani, K. Leung
- Computer Science
- IEEE Wireless Communications and Networking…
- 1 March 2007

Wireless sensors are expected to be widely deployed in the near future for a vast variety of applications. Sensing data is not useful unless the location where the data is collected is also known to… Expand
