Densify Your Labels: Unsupervised Clustering with Bipartite Matching for Weakly Supervised Point Cloud Segmentation
We propose a weakly supervised semantic segmentation method for point clouds
that predicts "per-point" labels from just "whole-scene" annotations while
achieving the performance of recent fully supervised approaches. Our core idea
is to propagate the scene-level labels to each point in the point cloud by
creating pseudo labels in a conservative way. Specifically, we over-segment
point cloud features via unsupervised clustering and associate scene-level
labels with clusters through bipartite matching, thus propagating scene labels
only to the most relevant clusters, leaving the rest to be guided solely via
unsupervised clustering. We empirically demonstrate that over-segmentation and
bipartite assignment plays a crucial role. We evaluate our method on ScanNet
and S3DIS datasets, outperforming state of the art, and demonstrate that we can
achieve results comparable to fully supervised methods.Comment: The first two authors contributed equally; Project website:

Current advances in~information quantum technologies - critical issues
This article reviews chosen topics related to the development of Information Quantum Technologies in the major areas of measurements, communications, and computing. These fields start to build their ecosystems which in the future will probably coalesce into a homogeneous quantum information layer consisting of such interconnected components as quantum internet, full size quantum computers with efficient error corrections and ultrasensitive quantum metrology nodes stationary and mobile. Today, however, the skepticism expressing many doubts about the realizability of this optimistic view fights with a cheap optimism pouring out of some popular press releases. Where is the truth? Financing of the IQT by key players in research, development and markets substantially strengthens the optimistic side. Keeping the bright side with some reservations, we concentrate on showing the FAST pace of IQT developments in such areas as biological sciences, quantum evolutionary computations, quantum internet and some of its components
A precarious lifestyle in the experience of grocery stores employees employed by the temporary employment agency "JOB MARKET Sp. z o.o." in Krakow.
Era globalizacji i rewolucja technologiczna ukształtowały współczesny rynek pracy, który obecnie jest oparty na neoliberalnych standardach konkurencyjności i indywidualizmu. To spowodowało, że coraz więcej pracodawców wykorzystuje elastyczny model organizacji pracy, w którym popularne staje się korzystanie z różnych form outsourcingu, takich jak na przykład korzystanie z usług agencji pracy tymczasowej. Skutkiem tych zmian było pojawienie się nowej kategorii społecznej, która doświadcza problemów niepewnej, tymczasowej i nisko płatnej pracy. Coraz więcej osób zatrudnianych jest na zasadzie elastycznych form zatrudnienia oraz bywa pozbawianych wielu form społecznych zabezpieczeń. Niektórzy socjologowie i ekonomiści nazywają tą kategorię społeczną mianem prekariatu. Głównym celem mojej pracy jest jakościowy opis stylu życia, który charakteryzuje osoby, doświadczające problemów prekarnej pracy. Ilustracją moich rozważań są wywiady z pracownikami sklepów spożywczych, zatrudnionymi przez agencję pracy tymczasowej „JOB MARKET” Sp. z o.o. w Krakowie.The era of globalization and the technological revolution have shaped the modern labour market, which is currently based on neoliberal standards of competitiveness and individualism. As a result, more and more employers are using a flexible work organization model in which the use of various forms of outsourcing is becoming popular, such as, for example, using the services of a temporary employment agencies. The result of these changes was the emergence of a new social category that experiences problems of precarious, temporary and low-paid jobs. More and more people are employed on the basis of flexible forms of employment and are deprived of many forms of social security. Some sociologists and economists call this social category the precariat. The main purpose of my thesis is a qualitative description of the lifestyle that characterizes people experiencing problems of precarious work. An illustration of my considerations are interviews with employees of grocery stores employed by the temporary employment agency "JOB MARKET Sp. z o.o." in Krakow
Metabolic syndrome is associated with similar long-term prognosis in non-obese and obese patients. An analysis of 45 615 patients from the nationwide LIPIDOGRAM 2004-2015 cohort studies
Aims We aimed to evaluate the association between metabolic syndrome (MetS) and long-term all-cause mortality. Methods The LIPIDOGRAM studies were carried out in the primary care in Poland in 2004, 2006 and 2015. MetS was diagnosed based on the National Cholesterol Education Program, Adult Treatment Panel III (NCEP/ATP III) and Joint Interim Statement (JIS) criteria. The cohort was divided into four groups: non-obese patients without MetS, obese patients without MetS, non-obese patients with MetS and obese patients with MetS. Differences in all-cause mortality was analyzed using Kaplan-Meier and Cox regression analyses. Results 45,615 participants were enrolled (mean age 56.3, standard deviation: 11.8 years; 61.7% female). MetS was diagnosed in 14,202 (31%) by NCEP/ATP III criteria, and 17,216 (37.7%) by JIS criteria. Follow-up was available for 44,620 (97.8%, median duration 15.3 years) patients. MetS was associated with increased mortality risk among the obese (hazard ratio, HR: 1.88 [95% CI, 1.79-1.99] and HR: 1.93 [95% CI 1.82-2.04], according to NCEP/ATP III and JIS criteria, respectively) and non-obese individuals (HR: 2.11 [95% CI 1.85-2.40] and 1.7 [95% CI, 1.56-1.85] according to NCEP/ATP III and JIS criteria respectively). Obese patients without MetS had a higher mortality risk than non-obese patients without MetS (HR: 1.16 [95% CI 1.10-1.23] and HR: 1.22 [95%CI 1.15-1.30], respectively in subgroups with NCEP/ATP III and JIS criteria applied). Conclusions MetS is associated with increased all-cause mortality risk in non-obese and obese patients. In patients without MetS obesity remains significantly associated with mortality. The concept of metabolically healthy obesity should be revised
