Winter School
NLDL 2024 Winter School
The PhD winter school will consist of tutorials by experts in the field and is co-hosted by NORA as part of the NORA Research School. A preliminary program is provided below.
Anyone who is interested can attend the winter school by registering for the conference on the Registration Page.
Getting formal ECTS Credits: UiT The Arctic University of Norway awards 5 ECTS for the Winter School for students who register formally for the course at UiT before the 1st of November (for credits, there is a limit of 40 students). To obtain credits, participants will be required to present an ongoing research project (poster presentation) as part of the winter school and complete a home exam afterward.

Course Description
Deep learning is a rapidly growing segment of machine learning. It is increasingly used to deliver near-human level accuracy for many tasks such as image classification, voice recognition and natural language processing. Applications areas include facial recognition, scene detection, advanced medical and pharmaceutical research, and autonomous, self-driving vehicles.
This 5-day course is build upon tutorials on specific topics on deep learning from perspectives such as Synthetic data, Generative Models, and Explainability. The course further encompasses among others keynote talks as well as special sessions on industry and diversity in AI as part of the NLDL conference program.
In particular, the winter school will provide a study of several emerging topics of high relevance within advanced deep learning, from a basic understanding of the techniques to the latest state-of-the-art developments in the field. Synthetic data generation for addressing common problems of data scarcity, privacy-preserving data sharing, and bias through case studies, reliability of AI, and generative models will be treated in depth in the form of tutorials, as will high-performance computing. Additional directions within deep learning, complementing those already mentioned, will be covered at the introductory level via a series of keynote talks. In addition, the participants will be exposed to the latest advances and applications in deep learning by the oral presentations and poster presentations in the main conference program.
The course will thus consist of 5 full days of the NLDL conference including: tutorials, keynote sessions, oral presentations and poster presentations, as well as practical components.

10-13 Tutorial: Innovative Uses of Synthetic Data Tutorial (Mihaela van der Schaar)
One of the biggest barriers to AI adoption is the difficulty to access high quality training data. Synthetic data has been widely recognised as a viable solution to this problem. It allows sharing, augmenting and de-biasing data for building performant and socially responsible AI algorithms. However, despite the significant progress in the theory and algorithm, the community still lacks a unified software that enables practical data sharing and access with synthetic data. This lab aims to bridge this gap by introducing synthcity, an open source Python library that implements an array of cutting edge synthetic data generators to address the problems of data generation due to its commonality in various applications.
13-14 Lunch
14-16 Tutorial: Generative Modeling with Variational Autoencoders (Rogelio A. Mancisidor)
Variational Autoencoders (VAEs) are probabilistic generative models used in different learning tasks, such as clustering, classification, representation learning or learning conditional distributions to generate new data. This tutorial presents different ways to derive the evidence lower bound (ELBO) to gain a deeper understanding of the advantages (e.g., representation learning and generative modeling in a single model) and disadvantages (e.g., posterior collapse or lack of flexibility in the latent space) of optimizing the ELBO. In addition, we will discuss how we can extend VAEs to the multimodality domain to learn conditional distributions, which enables cross-modal generation. By the end of this tutorial, you will have a good understanding of the main advantages of VAEs and why VAEs are a popular choice of generative models, as well as insight into some of the challenges posed by the probabilistic aspect of VAEs.
16:30-18:00 Poster Presentations
Friday January 12th:
09-11 Tutorial: Coding a Diffusion model from scratch (Filippo Maria Bianchi)
Renowned for their exceptional capabilities in synthesizing realistic images, audio, and video, DDPMs have marked a new era in generative modeling. In this introductory tutorial, we will dive into the world of Denoising Diffusion Probabilistic Models (DDPM) by unraveling the theory behind these groundbreaking generative models. In particular, we will closely look at the vanilla DDPM by implementing it from scratch using Pytorch and then using it to generate images from the popular Fashion MNIST dataset. At the end of the tutorial, you will have gained a robust understanding of DDPMs and also acquired the practical skills to build and apply these models to real data.
