The next seminar of the A3SI team of the LIGM (mixed research unit of the University Paris Est) will take place on Wednesday, September 5 at 9:30 (ESIEE PARIS). The room will be specified later. Stochastic geometry, topological and experimental Herbert Edelsbrunner IST Austria Abstract: We study classical questions in stochastic geometry, such as the expected density of p-simplices in the Delaunay mosaic of a Poisson point process in d-dimensional Euclidean space.  Using a discrete Morse theory ap ...

A seminar of the A3SI and LRT teams of the LIGM (joint research unit of Paris Est University) took place on Friday, June 22 from 1:30 pm to 2:30 pm at ESIEE Paris. Study of compressed stack algorithms in limited memory environment Jean-Francois Baffier Tokyo Intistute of Technology Abstract: The need to run algorithms on limited-memory devices motivated our consideration for data structure in the settings where there is only a limited amount of memory available (apart from the input representation). We ...

A seminar of the A3SI team of the LIGM (mixed research unit of Paris Est University) will take place on Monday, July 2nd from 1:30 pm to 2:30 pm, room 3005 (ESIEE PARIS). Watershed: how to learn it end-to-end, and how to use it in graph partitioning Fred Hamprech tHeidelberg University Abstract: In a first part, I will sketch how to realize an end-to-end learning of a segmentation pipeline involving a watershed computation [Wolf et al., "Learned Watershed", ICCV 2017]. In a second part, I will ...

A seminar of the A3SI team of the LIGM (joint research unit of Paris Est University) will take place on Tuesday, May 29 at 15:30, in the meeting room B 412 of the IMAGINE group (ENPC - Bat Coriolis). Self-supervision, Meta-supervision, Curiosity: Making Computers Study Harder Alexei Efros UC Berkeley Abstract: Computer vision has made impressive gains through the use of deep learning models, trained with large-scale labeled data. However, labels require expertise and curation and are expensive to col ...

Supervised Transform Learning Jyoti Maggu IIIT Delhi Abstract: Representation learning techniques have gained popularity over the years. Machine Learning community is well aware of several representation learning tools, viz. AutoEncoders, Deep belief networks, Convolutional Neural Networks and Dictionary Learning(similar to matrix f ...

A seminar of the A3SI team of the LIGM (joint research unit of the University Paris Est) will take place on Thursday, May 24 at 14h, in the meeting room B 412 of the group IMAGINE (ENPC - Bat Coriolis). Multilinear compressive sensing and an application to convolutional linear networks François Malgouyres Institut de Mathématiques de Toulouse Abstract: We study a deep linear network expressed under the form of a matrix factorization problem. It takes as input a matrix X obtained by multiplying K matric ...

The A3SI team of the LIGM (Joint Research Unit of the University of Paris East) is organizing a PhD workshop on Thursday 8th December from 13:30 to 15:00 at ESIEE Paris (Amphi 160). Three PhD students will present their work: Martin Simonovsky, LIGM, A3SI, IMAGINE A Deep Metric for Multimodal Registration Multimodal registration is a challenging problem in medical imaging due the high variability of tissue appearance under different imaging modalities. The crucial component here is the choice of t ...

The A3SI team of the LIGM (Joint Research Unit of the University of Paris East) has been collaborating with several Brazilian universities for more than 20 years. On the occasion of the visit to France of Arnaldo de Albuquerque Araújo (post-doc in the team in 1994), a Franco-Brazilian workshop of image analysis is organized Thursday, December 8 from 10:00 to 12:00, amphi 110 (ESIEE PARIS). Six doctoral students will present their work in a Franco-Brazilian research context: Combinations of hierarchical ...

Seminar of Professor HONGLONG CHANG of NORTHWESTERN POLYTECHNICAL UNIVERSITY, XI'AN, CHINA Wednesday, October 4 at 14:30 at ESIEE Paris. A new inertial sensing paradigm based on weakly coupled resonators Abstract Weakly coupled resonators (WCRs) have demonstrated several interesting phenomena such as eigenvalue loci veering, energy confinement, mode localization. This talk will review more interesting phenomena of WCRS such as anti-resonance loci, mode interaction, quantization of the mode local ...
