Saddle-to-Saddle Dynamics in Diagonal Linear Networks

Nicolas Henri Bernard Flammarion, Scott William Pesme

In this paper we fully describe the trajectory of gradient flow over diagonal linear networks in the limit of vanishing initialisation. We show that the limiting flow successively jumps from a saddle of the training loss to another until reaching the minim ...

The rationales that underlie modal practices

Vincent Kaufmann

Encouraging a modal shift from individual transportation to less polluting modes such as public transport, walking and cycling, is now a key recommendation of the UN to reach the goals set by the Paris Agreement. Achieving this ambitious goal requires a de ...

Individual changes in the bicycle community workshops, A typology from a new agent of socialization

Alexandre André Robert Rigal

Social change is at the center of solutions to the problems of the environment. Yet social change is sometimes elusively described. Through empirical inquiries guided by socialization theories, the present article aims to identify different types of indivi ...

Comment se modifient les logiques de mobilité sur un campus universitaire?

Lucie Arnaudon

More than 16, 000 people reach the EPFL campus every day by public transport, private car or non-motorised transports. According to the EPFL "Mobility Survey 2019", 22% of students commute by bicycle (compared to 20% of staff), but still 30% of the staff c ...

Advanced design methods and non-ideal gas lubrication applied to aerodynamic bearings

Eliott Philippe Guenat

Clean and energy-efficient turbomachinery are playing an increasingly important role in the decarbonization of heating systems, waste heat recovery and transportation, as the use of small-scale heat pumping and fuel cells spreads. Such machines typically e ...

On the manufacturing of compliant foil bearings

Jürg Alexander Schiffmann, Karim Magdi Zakaria Abdelrahman Shalash

The fabrication of foil bearings is challenging due to the dependence on sheet metal forming to produce the compliant structure. This paper is an attempt to shed light into the foil bearing manufacturing know-how. Design of experiments techniques are used ...

Unpredictability does not hamper nonretinotopic motion perception

Michael Herzog, Marc Michael Lauffs

The motion of parts of an object is usually perceived relative to the object, i.e., nonretinotopically, rather than in retinal coordinates. For example, we perceive a reflector to rotate on the wheel of a moving bicycle even though its trajectory is cycloi ...

Foldable Drones: from Biology to Technology

Dario Floreano, Stefano Mintchev, Jun Shintake

Current drones are developed with a fixed morphology that can limit their versatility and mission capabilities. There is biological evidence that adaptive morphological changes can not only extend dynamic performances, but also provide new functionalities. ...
