Unified Long-Term Time-Series Forecasting Benchmark

1 code implementation27 Sep 2023 Jacek Cyranka, Szymon Haponiuk

In order to support the advancement of machine learning methods for predicting time-series data, we present a comprehensive dataset designed explicitly for long-term time-series forecasting.

Improved Overparametrization Bounds for Global Convergence of Stochastic Gradient Descent for Shallow Neural Networks

no code implementations28 Jan 2022 Bartłomiej Polaczyk, Jacek Cyranka

Second, we provide a technical result (working also for general approximators) relating solutions of the aforementioned differential inclusion to the (discrete) stochastic gradient descent sequences, hence establishing linear convergence towards zero loss for the stochastic gradient descent iterations.

SPP-RL: State Planning Policy Reinforcement Learning

no code implementations29 Sep 2021 Jacek Cyranka, Zuzanna Opała, Jacek Płocharczyk, Mikhail Zanka

We introduce an algorithm for reinforcement learning, in which the actor plans for the next state provided the current state.

On The Verification of Neural ODEs with Stochastic Guarantees

no code implementations16 Dec 2020 Sophie Gruenbacher, Ramin Hasani, Mathias Lechner, Jacek Cyranka, Scott A. Smolka, Radu Grosu

We show that Neural ODEs, an emerging class of time-continuous neural networks, can be verified by solving a set of global-optimization problems.

Lagrangian Reachtubes: The Next Generation

Secondly, it computes the next reachset as the intersection of two balls: one based on the Cartesian metric and the other on the new metric.

Mapper Based Classifier

2 code implementations17 Oct 2019 Jacek Cyranka, Alexander Georges, David Meyer

We propose a classifier based on applying the Mapper algorithm to data projected onto a latent space.
