Learning to Infer from Unlabeled Data: A Semi-supervised Learning Approach for Robust Natural Language Inference
Natural Language Inference (NLI) or Recognizing Textual Entailment (RTE) aims
at predicting the relation between a pair of sentences (premise and hypothesis)
as entailment, contradiction or semantic independence. Although deep learning
models have shown promising performance for NLI in recent years, they rely on
large scale expensive human-annotated datasets. Semi-supervised learning (SSL)
is a popular technique for reducing the reliance on human annotation by
leveraging unlabeled data for training. However, despite its substantial
success on single sentence classification tasks where the challenge in making
use of unlabeled data is to assign "good enough" pseudo-labels, for NLI tasks,
the nature of unlabeled data is more complex: one of the sentences in the pair
(usually the hypothesis) along with the class label are missing from the data
and require human annotations, which makes SSL for NLI more challenging. In
this paper, we propose a novel way to incorporate unlabeled data in SSL for NLI
where we use a conditional language model, BART to generate the hypotheses for
the unlabeled sentences (used as premises). Our experiments show that our SSL
framework successfully exploits unlabeled data and substantially improves the
performance of four NLI datasets in low-resource settings. We release our code

Hierarchical Multi-Label Classification of Scientific Documents
Automatic topic classification has been studied extensively to assist
managing and indexing scientific documents in a digital collection. With the
large number of topics being available in recent years, it has become necessary
to arrange them in a hierarchy. Therefore, the automatic classification systems
need to be able to classify the documents hierarchically. In addition, each
paper is often assigned to more than one relevant topic. For example, a paper
can be assigned to several topics in a hierarchy tree. In this paper, we
introduce a new dataset for hierarchical multi-label text classification
(HMLTC) of scientific papers called SciHTC, which contains 186,160 papers and
1,233 categories from the ACM CCS tree. We establish strong baselines for HMLTC
and propose a multi-task learning approach for topic classification with
keyword labeling as an auxiliary task. Our best model achieves a Macro-F1 score
of 34.57% which shows that this dataset provides significant research
opportunities on hierarchical scientific topic classification. We make our
dataset and code available on Github.Comment: Accepted in EMNLP 2022 main conferenc
Prevalence of Fimeria funduli (Protozoa: Eimeriidae) in the Longnose Killifish Fundulus similis from Horn Island, Mississippi
Eimeria funduli occurred in Fundulus similis from Horn Island, Mississippi, during 1980, in contrast with its apparent absence during 1978 and 1979. Prevalence of the parasite appears to be related to the unusually low salinity in Mississippi Sound, and in ponds and off the beaches of Horn Island. The low salinity may have promoted the migration of infective intermediate hosts from inshore waters to the island
A Selected Bibliography on the Mass Propagation of Rotifers with Emphasis on the Biology and Culture of Brachionus plicatilis
The rotifer Brachionus plicatilis has shown great promise as food for artificially reared fish and crustacean larvae. A list of references on mass propagation of rotifers is presented alphabetically by author. Citations cover and are indexed as culture, diet, ecology, physiology, population dynamics, reproduction, systematics, geographical distribution, food, and biology of rotifers with emphasis on Brachionus plicatilis
Evaluation of Flow-Through, Static, and Recirculating Systems for the Intensive Culture of the Gulf Killifish Fundulus grandis with Observations on a Solar-Heated Recirculating System for the Bait Industry
Three systems (flow-through, static, and recirculating) for intensive culture of the Gulf killifish (Fundulus grandis) for bait were evaluated. The outdoor recirculating system proved most successful. Killifish maintained in this system attained an average weight of over 2.0 gm in 42 days, an acceptable market size. Whereas the solar-heated recirculating system sustained fish densities equivalent to 1,000,000/ha and a survival rate of 86%, growth of killifish in this system was less than that observed in both the static and outdoor recirculating systems. Algae appeared to be an important nutritional component of the diet of juvenile killifish. Individuals of F. grandis fed diets supplemented with algae grew better than those maintained without them
Preliminary Observations of the Effect of Eimeria funduli (Protozoa: Eimeriidae) on the Gulf Killifish Fundulus grandis and Its Potential Impact on the Killifish Bait Industry
Liver infections of Eimeria funduli, a pathogenic coccidium, greatly affected growth of Fundulus grandis (Gulf killifish) maintained in an aquaculture facility for 55 days. At termination of the experiment, average weight gained by uninfected killifish was 877.5% compared to 308.0% in diseased fish. There appeared to be no correlation between mortality and disease in this study

Hesitant Probabilistic Fuzzy Preference Relations in Decision Making
Preference of an alternative over another alternative is a useful way to express the opinion of decision maker. In the process of group decision making, preference relations are used in preference modelling of the alternatives under given criteria. The probability is an important tool to deal with uncertainty; in many scenarios of decision making probabilities of different events affect the decision making process directly. In order to deal with this issue, in this paper, hesitant probabilistic fuzzy preference relation (HPFPR) is defined. Furthermore, consistency of HPFPR and consensus among decision makers are studied in the hesitant probabilistic fuzzy environment. In this respect, many novel algorithms are developed to achieve consistency of HPFPRs and reasonable consensus between decision makers and a final algorithm is proposed comprehending all other algorithms, presenting a complete decision support model for group decision making. Lastly, we present a case study with complete illustration of the proposed model and discussed the effects of probabilities on decision making validating the importance of the introduction of probability in hesitant fuzzy preference relation
Epikrise i hånden: Bedre enn 10 i systemet?
Bakgrunn/emne:
Brukermedvirkning og samhandling er viktige satsningsområder i arbeidet for å sikre god pasientsikkerhet og kvalitet i helsevesenet. Å involvere pasienten i egen sykdom og behandling, samt sikre at denne informasjonen raskt formidles mellom første- og annenlinjetjenesten, er nødvendig for å kunne bedre pasientsikkerheten. Epikrisen er et sentralt verktøy for å oppnå dette. Vi ønsker å undersøke hvordan innføring av ”epikrise i hånden” (EIH) til pasienten ved utskrivelse fra sykehusavdeling påvirker epikrisetid og pasienttilfredshet, og se på hvilke tiltak som kan være aktuelle for å gjennomføre dette.
Kunnskapsgrunnlag:
Ved litteratursøk fant vi gode erfaringer fra gjennomføring av EIH i Norge. Pasientene ønsker å motta informasjonen som er i epikrisen, de fleste opplever bedre egenhelse, og er mer fornøyde med behandlingen. Epikrisetiden har gjennomgående blitt betraktelig redusert og kommunikasjonen med andrelinjetjenesten har blitt styrket.
Begrunnet tiltak og metode:
Vi søkte i tilgjengelig litteratur, intervjuet leger i kliniske avdelinger og benyttet oss av egne erfaringer fra praksisperioden i 10.semester. Avhengig av avdelingens eksisterende rutiner og arbeidsverktøy, vil vi foreslå flere mindre tiltak. Både talegjenkjenning, digital diktering, omorganisering av sekretærtjenesten og endring av arbeidsflyten i avdelingen kan være aktuelt, sammen eller hver for seg, tilpasset de ulike avdelingers rammevilkår.
Organisering:
Forslaget vårt er at det i den aktuelle avdelingen nedsettes en tverrfaglig prosjektgruppe, som etter et PDSA-mønster implementerer EIH som utskrivelsespraksis i en prøveperiode. Etter prøveperioden må arbeidsgruppen vurdere effektene av tiltaket, og vurdere om det er ønskelig å implementere EIH som fast praksis.
Resultater/vurdering:
Målet med å innføre EIH er todelt: at pasienten blir mer involvert i egen helse og behandling, samt å øke andelen epikriser som sendes ut i løpet av den nasjonale syvdagersfristen slik at kommunikasjonen mellom ulike nivåer i helsetjenesten bedres. Begge delmål bidrar til økt pasientsikkerhet. Mål på førstnevnte vil være økt pasienttilfredshet, målt kvalitativt ved et strukturert spørreskjema. Epikrisetiden kan raskt kontrolleres ved å sjekke utsendelsesdatoen opp mot utskrivelsesdato, noe som er et indirekte mål på hvorvidt EIH er gjennomført
