Background

A desirable side-effect of the NLPL cooperation is community formation, i.e. strengthening interaction and collaboration among Nordic research teams in NLP and advancing a shared level of knowledge and experience in using national e-Infrastructures for large-scale NLP research. Towards these goals, the project organizes an annual three-day winter school. For additional background, please see the archival pages from the 2018 NLPL Winter School.

For early 2019, NLPL will hold its winter school from Monday, February 4, to Wednesday, February 6, 2019, at a mountain-side hotel (with skiing opportunities) about two hours north of Oslo. The project will organize group bus transfer from and to the Oslo airport Gardermoen, leaving the airport at 9:30 on Monday morning and returning there around 17:30 on Wednesday afternoon.

The main instructors in 2019 will be Chris Dyer and Graham Neubig, core developers of the DyNet framework, for a combination of lectures and hands-on exercises in applications of ‘dynamic’ deep neural networks to NLP. The winter school programme will be complemented with a ‘walk-through’ of available software, data, and service resources from NLPL, as well as with a ‘research bazar’ involving all participants.

The winter school is subsidized by the project (with financial support from NeIC). There will be a limited number of fully funded ‘slots’ available to members of the core NLPL consortium, which each partner is free to allocate among their staff and student as they see fit. Additionally, the winter school will welcome partly self-funded participants from project partners and other Nordic NLP research centers, who will have to cover their own travel expenses to and from Oslo airport, as well as their cost of accommodation at the winter school hotel (the latter is expected to come to at most NOK 2,500). In total, we anticipate 30–35 participants in the 2019 Winter School.

Logistics

NLPL Winter School participants will meet at the meeting point in the Arrival hall at OSL. On this map of the OSL Arrival hall the meeting point is marked below the kiosks numbered 27 and 34: https://avinor.no/globalassets/_oslo-lufthavn/ankomst-arrivals-2018-3.pdf. Be at the meeting point at 09:00 (CET) 4. February, 2019. We will walk to the bus terminal together, leaving OSL shortly after 09:00. The bus will arrive at Skeikampen around 12:00 (CET). Lunch will be served upon our arrival, which currently is scheduled for 12:30(CET).

The Winter School will end with lunch on Wednesday 6. February, before we get on the bus to the Airport. The bus will leave Skeikampen at 14:00(CET). Expected arrival time at OSL Airport is 17:00(CET). When planning your flights, you should leave room for possible delays due to the season (slippery roads, heavy snow fall and so on).

Registration

We ask all interested parties (from NLPL project sites, associates, or other NLP research groups in Northern Europe) to register their interest in participation through the on-line registration form The deadline for requesting involvement was Friday, December 7, 2019; registration is now closed. Registration through this form does not automatically qualify for participation in the winter school, however.

Each NLPL partner site will have available three ‘fully subsidized’ (within Norway) slots, which will be confirmed by the local site manager: Anders Sørgaard at Copenhagen University, Leon Derczynski at IT University Copenhagen, Jörg Tiedemann at Helsinki University, Stephan Oepen at the University of Oslo, Filip Ginter at the University of Turku, and Joakim Nivre at Uppsala University).

In addition to these slots, five to ten additional participants will be welcome to participate partly at their own expense, i.e. covering the cost of accomodation at Skeikampen (and, of course, travel to and from Oslo airport) themselves. The NLPL outreach task force will review registrations in mid-December 2019 and then finally confirm participation by non–project members, based on a combination of the first come–first served principle and a goal of institutional and regional diversity.

Software Environment

Graham uses code from https://github.com/neubig/nn4nlp-code .

There is an installation of DyNet (so far without GPU support) available on Abel:

module use -a /projects/nlpl/software/modulesfiles
module load nlpl-dynet

Subsized Participants

In early December 2018, there has been great interest in participation already (and registration technically remains open), and we will regrettably have to decline numerous prospective participants. In a first round of allocations, we are currently confirming participation from members of the core consortium (including associate partners), who will have their cost of staying at the conference site covered directly by NeIC. Everyone else, please expect to hear more from us by mid-December.

Self-Funded Participants

Our public call for participation was met with great interest by NLP researchers from all over Northern Europe (and beyond). A total of 54 registrations were received by the deadline, of which six have been declined for various reasons. Everyone else (who as of December 10 has yet to hear from us) will be invited to participate on a self-funding basis, meaning that these participants will have to pay their own accomodation and meals while at Skeikampen (but are of course not expected to contribute to the cost of transfer between the Oslo airport and the hotel or otherwise pay a participation fee). Bjørn Lindi, the NLPL project manager, will email pre-registered participants by December 15, 2018, with more information on the cost for self-funded participation and the process for confirming your involvement.
