Grasping Student: semi-supervised learning for robotic manipulation
Piotr Krzywicki, Krzysztof Ciebiera, Rafał Michaluk +2
Gathering real-world data from the robot quickly becomes a bottleneck when constructing a robot learning system for grasping. In this work, we design a semi-supervised grasping sys…
Polite Teacher: Semi-Supervised Instance Segmentation with Mutual Learning and Pseudo-Label Thresholding
Dominik Filipiak, Andrzej Zapała, Piotr Tempczyk +2
We present Polite Teacher, a simple yet effective method for the task of semi-supervised instance segmentation. The proposed architecture relies on the Teacher-Student mutual learn…
On Many-Actions Policy Gradient
Michal Nauman, Marek Cygan
We study the variance of stochastic policy gradients (SPGs) with many action samples per state. We derive a many-actions optimality condition, which determines when many-actions SP…
One Simple Trick to Fix Your Bayesian Neural Network
Piotr Tempczyk, Ksawery Smoczyński, Philip Smolenski-Jensen +1
One of the most popular estimation methods in Bayesian neural networks (BNN) is mean-field variational inference (MFVI). In this work, we show that neural networks with ReLU activa…
n-CPS: Generalising Cross Pseudo Supervision to n Networks for Semi-Supervised Semantic Segmentation
Dominik Filipiak, Piotr Tempczyk, Marek Cygan
We present n-CPS - a generalisation of the recent state-of-the-art cross pseudo supervision (CPS) approach for the task of semi-supervised semantic segmentation. In n-CPS, there ar…
Tight Bounds on Subexponential Time Approximation of Set Cover and Related Problems
Marek Cygan, Magnús M. Halldórsson, Guy Kortsarz
We show that Set Cover on instances with elements cannot be approximated within -factor in time exp(, for any and any , assuming the Expo…
