Show summary
Understanding diverse demographic groups presents a significant challenge in market research. In this paper, we introduce a novel system that integrates large language models with genetic algorithms to create synthetic personas capable of generating feedback that approximates real-world human responses. Our experimental evaluation demonstrates that synthetic personas not only exhibit age-differentiated technology usage patterns consistent with documented trends but also benefit from genetic algorithm optimization, which improves response accuracy from 60.4% to 78.5% on training questions and from 62.6% to 68.8% on hidden questions—outperforming human estimators. Moreover, the optimized personas achieve a 51.1% better correspondence with actual income distributions compared to random profiles. This approach makes it possible to rapidly generate feedback without requiring participants, facilitates iterative follow-ups, and systematically enhances demographic representativeness.

Show summary
Probabilistic sampling in machine learning models is a technique for introducing beneficial randomness and variability during output generation. It enhances output diversity and creativity, particularly in tasks where slight variations can lead to novel and interesting results. Large Language Models (LLMs), for instance, use this technique to generate varied, contextually appropriate responses that mirror the flexibility of human language. This paper presents a novel method for training a neural network to output the defining parameters of one Probability Density Function (PDF) for each dimension in an embedding space. Our approach, Dimensional-PDFs for Embedding Space Sampling (DESS), leverages these PDFs at inference time to sample from an embedding space, offering a new approach to probabilistic sampling in model outputs. Our method employs simple loss functions and a multi-step loss computation to learn both mean and variance parameters without requiring sampling during training, making it computationally efficient and easy to integrate with existing architectures. We validate DESS through controlled experiments on synthetic datasets, demonstrating accurate approximations of ground-truth distribution parameters across varying Gaussian target distributions. The framework has potential applications in large-vocabulary models where it could enable significant parameter reductions while maintaining calibrated uncertainty estimates. We present DESS using normal distributions, though the approach can be extended to other distribution types for specific sampling requirements.

Document chunking fundamentally impacts Retrieval-Augmented Generation (RAG) by determining how source materials are segmented before indexing. Despite evidence that Large Language Models (LLMs) are sensitive to the layout and structure of retrieved data, there is currently no framework to analyze the impact of different chunking methods. In this paper, we introduce a novel methodology that defines essential characteristics of the chunking process at three levels: intrinsic passage properties, extrinsic passage properties, and passages-document coherence. We propose HOPE (Holistic Passage Evaluation), a domain-agnostic, automatic evaluation metric that quantifies and aggregates these characteristics. Our empirical evaluations across seven domains demonstrate that the HOPE metric correlates significantly (𝜌 > 0.13) with various RAG performance indicators, revealing contrasts between the importance of extrinsic and intrinsic properties of passages. Semantic independence between passages proves essential for system performance with a performance gain of up to 56.2% in factual correctness and 21.1% in answer correctness. On the contrary, traditional assumptions about maintaining concept unity within passages show minimal impact. These findings provide actionable insights for optimizing chunking strategies, thus improving RAG system design to produce more factually correct responses.

Road accidents leads to a significant number of deaths in the world, with human error being attributed as one of the roots of the problem. One of the possible alternatives to address the issue is the development of autonomous vehi-cles. Of the many technological advancements in the field of autonomous vehicles, Reinforcement Learning (RL) has shown progress because its methodology is not reliant on human data. However, one of its challenges is the definition of the reward function, which is critical to RL algorithms. In this context, determining the severity of a crash allows for an improvement in the reward function, especially in simulators. In this study, we present a Deep Neural Network (DNN) based model that predicts the crash impact severity in terms of vehicle deformation during the event, along with the de-formation we create a reward strategy for RL- based vehicle simulators. The model is developed based on data generated from finite element simulations replicating a full-frontal vehicle impact against a rigid barrier. We compare the trained model with a variety of NN methods, and different input data. The Neural Network model performs well, supporting the development of a reward system to improve RL-based autonomous vehicle simulators.

Abstract. Named Entity Recognition (NER) is crucial for many Nat-
ural Language Processing (NLP) applications, yet current models of-
ten lack explainability and robustness, particularly against lexical varia-
tions. While methods like Local Interpretable Model-agnostic Explana-
tions (LIME) have enhanced explainability in text classification, their
application to sequence-based tasks like NER remains an open chal-
lenge. This paper introduces the NER Explainability Framework (NEF),
a novel approach that transforms the sequence-based NER task into a
multi-classification problem. This transformation enables the application
of LIME to any NER architecture. NEF provides precise, interpretable
insights into model decisions by highlighting which parts of the input text
most influence tagging decisions, significantly advancing explainability in
NER. To address the critical gap in assessing model resilience, we also
present the Misspelling Robustness Score (MRS), a new metric designed
to quantify NER model resilience against lexical variations, particularly
misspellings. MRS offers a comprehensive evaluation of model perfor-
mance in the face of spelling variations and errors. We apply NEF to four
widely used NER models (SpaCy, Flair, Stanza, and RoBERTa) using the
CoNLL-2003 dataset, revealing critical patterns and weaknesses in model
behavior. Our method enables targeted improvements, demonstrated by
fine-tuning the SpaCy model to achieve a significant 17.5% increase in
robustness against misspellings. These findings lay the groundwork for
developing more robust, accurate, and interpretable NER systems, pro-
viding practical strategies to address existing challenges in NLP. The
universal applicability of NEF across NER architectures and the insights
provided by MRS offers valuable tools for researchers and practitioners
in advancing the field of NER.

Show summary
Text embedding models trained on vast web-scraped corpus generalize well to daily language. However, they often fall short when applied in specialized domains that require precise language and foreign terms, like law and medicine. This gap highlights the necessity for data-efficient methodologies to fine-tune these models for narrow-domain applications. This paper introduces PlanBERT, a new approach for enabling data-efficient domain adaptation and fine-tuning of embedding models. The approach builds on self-supervised contrastive pre-training, synthetic training data generated by large language models (LLMs), and decorrelation of embedding features. The paper also introduces the term “informative vector embeddings” to adjust the training objectives to incentivise more analytics-friendly embeddings and demonstrate that PlanBERT can learn the domain language of zonal plans and outperform larger and more complex state-of-the-art models in challenging real-world zonal plan tasks.

Show summary
Prosjektet har kartlagt hvordan fremvoksende digitale teknologier som kunstig intelligens, skytjenester, robotisering, smartoveråking og fjernstyring samt utvidet og virtuell virkelighet tas i bruk i arbeidslivet og hvordan bruken påvirker innholdet i arbeidsoppgaver og jobber. Formålet har vært å belyse hvordan disse endringene påvirker behovet for kompetanse og hvilke strategier arbeidsgivere og arbeidstakere benytter for å møte nye krav og forventninger. Vi har også undersøkt hva som hemmer og fremmer kompetanseutvikling i møte med ny digital teknologi. Rapporten bygger på spørreundersøkelser rettet mot både arbeidsgivere og ansatte, utført av Norstat, samt case-studier innenfor næringene helse- og omsorg, industri, varehandel og informasjon og kommunikasjon. I tillegg er flere enn 11 000 stillingsannonser fra Navs stillingsdatabase analysert ved hjelp av KI for å undersøke hva slags digital kompetanse arbeidsgivere etterspør i rekrutteringsprosesser.
Rapportens hovedfunn er at jobber i hovedsak endrer innhold, snarere enn å forsvinne som følge av automatisering. De fleste, både blant arbeidsgivere og arbeidstakere, opplever også at virksomhetene henger med i utviklingen. Ansatte ser i hovedsak ut til å møte nye kompetansebehov som oppstår. Samtidig ser vi tendenser til at det blir økende «strekk i laget», særlig med hensyn til kompetanse innen kunstig intelligens. Det er en generell tendens til at ansatte med lav kompetanse er mindre tilbøyelige til å delta i opplæring og til å prøve seg fram. Virksomheter som ser ut til å lykkes best med kompetanseutvikling i møte med digital teknologi lager gode rammer og systemer rundt uformell læring: De bygger opp ansatte med interesse, lærevillighet og et godt kompetansemessig utgangspunkt og lar dem innta mer formaliserte roller, der de kan bidra til å spre læringen i organisasjonen. De kombinerer strategier for å sikre et grunnplan av felles forståelse og kunnskap med spesialiserte utviklingsmuligheter for dem som har behov for spisskompetanse.
Vi peker til slutt på at økt digitalisering også innebærer økt sårbarhet. Trusselbildet i det digitale rom og den geopolitiske utviklingen skaper et mer akutt behov for grunnleggende digital kompetanse i det brede lag av befolkningen. Behovet for spesialistkompetanse kan også øke, for å bygge opp europeiske og nasjonale alternativer til amerikanske og kinesiske teknologiplattformer. Etter en lang periode med stabil, institusjonalisert internasjonal utveksling, som gjorde det enkelt for næringsliv og akademia å rekruttere, samarbeide og spesialisere seg på tvers av landegrenser, gir innføring av tollmurer og handelsbarrierer færre muligheter til å lene seg på internasjonal arbeidsdeling. Det gir behov for å definere hva som utgjør «kritisk nasjonal kompetanse», som et supplement til kritisk infrastruktur, og å sørge for at Norge har tilgang på slik kompetanse.
