Few shot learning (with hypernetworks)Few shot learning , Meta Learning Few-shot learning (FSL), also referred to as low-shot learning (LSL) in few sources, is a type of machine learning problems where the training dataset contains limited information. Few-shot learning aims for Deep learning models to predict the correct class of instances when a small amount of examples are available in the training dataset.

Interpretable Latent Space Interpolation in Molecular/Graph Generative Models deep learning, cheminformatics, autoencodersThe goal of this project is to interpolate in the latent space of an autoencoder model so that molecules (graphs) from the interpolation path use only "legal" operations. Legal operations in chemistry are those that can be achieved in a chemical reaction. More generally, each interpolation step in graphs should involve one operation such as adding nodes, removing nodes, or modifying connections in the graph.Tomasz Danel, Igor Podolaktomasz.danel[AT]
Graph Convolution Neural NetworkGraph Convolution Neural NetworkGraph Convolutional Networks (GCNs) have recently become the primary choice for learning from graph-structured data, superseding hash fingerprints in representing chemical compounds. However, GCNs lack the ability to take into account the ordering of node neighbors, even when there is a geometric interpretation of the graph vertices that provides an order based on their spatial positions. To remedy this issue, we propose Geometric Graph Convolutional Network which uses spatial features to efficiently learn from graphs that can be naturally located in space. Our contribution is threefold: we propose a GCN-inspired architecture which (i) leverages node positions, (ii) is a proper generalisation of both GCNs and Convolutional Neural Networks (CNNs), (iii) benefits from augmentation which further improves the performance and assures invariance with respect to the desired properties.Przemysław Spurek

Uncertainty estimation for early-exit methods improvementconditional computation, uncertaintyEarly-exit methods decrease processing time for "easy" samples. Usually, the entropy or confidence (max softmax probability) of a head is compared to a threshold to decide whether to exit early. However, it is not clear if this is the best design choice. Fortunately, multiple computationally cheap uncertainty estimation methods were published recently. This project would explore the application of that methods for improvement of early-exit results (inference time and accuracy). Student would have to reimplement two or three (simple) uncertainty estimation methods - described in published papers - in a early-exit setup. Depending on their preferences, the student can start with a given code repository or from scratch.Bartosz Wójcikbartwojc[AT]gmail.comYESPyTorch

Augumenting SGD optimizers with low dimensional 2nd order information
SGD optimization
SGD optimization is currently dominated by 1st order methods like Adam. Augumenting them with 2nd order information would suggest e.g. optimal step size. Such online parabola model can be maintained nearly for free by extracting linear trends of the gradient sequence (arXiv: 1907.07063), and is planned to be included for improving standard methods like Adam.

Non-Gaussian Gaussian Processesdeep learning, meta-learning, few-shot learning, regression, gaussian processes, normalizing flowsGaussian Processes (GPs) have been widely used in machine learning to model distributions over functions, with applications including multi-modal regression, time-series prediction, and few-shot learning. GPs are particularly useful in the last application since they rely on Normal distributions and, hence, enable closed-form computation of the posterior probability function. Unfortunately, because the resulting posterior is not flexible enough to capture complex distributions, GPs assume high similarity between subsequent tasks – a requirement rarely met in real-world conditions. In this work, we address this limitation by leveraging the flexibility of Normalizing Flows to modulate the posterior predictive distribution of the GP, which makes the GP posterior locally non-Gaussian.Marcin Sendera, Jacek Tabor, Aleksandra Nowak, Andrzej Bedychaj, Massimiliano Patacchiola, Tomasz Trzciński, Przemysław Spurek, Maciej Ziębamarcin.sendera[AT]
