The best day of the year! I have been so fortunate to attract such amazing talent: @JiahuiLei1998 @EChatzipantazis @WenJiang_PL walked today (see pic), two more are graduating this year @xu_yinshua86846 and @ZiyunClaudeWang !

[Symmetry and Geometry in Neural Representations @neur_reps]

While you're oscillating between @unireps and @NeurReps, stop by NeurReps to hear from Evangelos Chatzipantazis (@EChatzipantazis) on

"BiEquiFormer: Bi-Equivariant Representations for Global Point Cloud Registration"!

[Kostas Daniilidis @KostasPenn]

Today at 4:30p in East Exhibit Hall A-C,
Poster #2210 #NeurIPS2024
@stefanos_pert , @EChatzipantazis and Shubendhu Trivedi @_onionesque will present our new approach to getting better (but approximate) equivariant models!

Hosting Tess Smidt ⁦@tesssmidt⁩ at the ⁦@GRASPlab⁩ Friday Seminar. Yes, roboticists, symmetry should be one of the first principles in robotics!

Join us on Monday October. 14th at 2pm (UTC+4) in #IROS2024 Workshop on Equivariant Robotics.
A great lineup of keynote speakers will discuss how symmetry penetrates each and every subfield of robotics.

Should have thought to make a serious post. But this work on improving training of equivariant NNs will appear at NeurIPS https://t.co/FnqHzyweF1
With Stefanos Pertigkiozoglou (@stefanos_pert) Evangelos Chatzipantazis (@EChatzipantazis), and Kostas Daniilidis (@KostasPenn).

[Shubhendu Trivedi @_onionesque]

Finally a paper in which my name is the simplest amongst the authors. :))

EqNIO: Subequivariant Neural Inertial Odometry

Royina Karegoudra Jayanth, @xu_yinshua86846, Ziyun Wang, @EChatzipantazis, @DanielGehrig6, @KostasPenn

tl;dr: symmetry of IMU data->subequivariance->nn+subequivariant basic layers->displacement & covariance

@EChatzipantazis and @stefanos_pert start the equivariance tutorial!

[Kostas Daniilidis @KostasPenn]

This is really fascinating. Nina Miolane ⁦@ninamiolane⁩ showing how biological brains encode Lie groups! #CVPR Equivision workshop

[Kostas Daniilidis @KostasPenn]

Our Equivariant Vision workshop features five great speakers @erikjbekkers @HaggaiMaron @ninamiolane @_machc, and Leo Guibas, spotlight talks, posters, and a tutorial prepared for the vision audience. Come tomorrow, Tuesday, at 8:30am in Summit 321! Thank you @CongyueD for leading the organization!

Fourier transform on groups turns convolution into multiplication. For non-commutative groups, it is matrix-matrix multiplication though … https://t.co/agPR4YN6eO https://t.co/A8RlE7CruM

1st post in a series accompanying our book on equivariant CNNs.
It is meant to give an easy intro to the main concepts/intuitions behind equivariant DL. I explain *what* equivariant NNs are, *why* they are desirable, and *how* to construct them.
