The academic career of the caterpillar track. Means of progression - Meaning of progress.
No full textDiscussing the forms of research that are relevant in higher art education, we can metaphorically use various means of progression. In that respect, the caterpillar track in particular stands out for Bert Willems. How can the caterpillar track provide insights into the way we look at and think about progress? We end up with the suggestion that the art school is a good environment for artistic researchers as happy, critical, but nonetheless intrusive explorers of reality
Kunstenaars denken
No full textKunstenaars en academici; hoe ver staan ze werkelijk van elkaar? In zijn essaybundel Kunstenaars denken verkent prof. dr. Bert Willems de positie van kunstenaars in de academische wereld vanuit een radicaal positieve instelling. Hij stelt voor om kunstenaars als integraal onderdeel van de academische gemeenschap te beschouwen en benadrukt dat het unieke denken van kunstenaars van waarde kan zijn voor alle betrokkenen.
Het ‘kunstenaarsdenken’ biedt een verfrissend perspectief in de context van de soms stugge academische wereld. Via zijn methode, die hij ‘metaforisch smeedwerk’ noemt, ontwikkelt Willems denk-beelden die in staat zijn om bestaande breuklijnen te overbruggen of zelfs weg te werken.
Hij denkt na over een open attitude die eenheid kan bevorderen vanuit verschillende en soms contrasterende gedachtegangen. Het is hem er niet om te doen om een vaststaand conceptueel systeem te formuleren, maar om de dialoog open te houden en vragen te stellen over wat kunstenaars en academici voor elkaar zouden kunnen betekenen.
De auteur mikt op een speelse benadering die een verbindend karakter geeft aan het debat en daardoor ruimte creëert voor verdere gesprekken
Onderzoek in de kunsten: het hoe en waarom van een artistiek onderzoeksproces
No full textDit handboek wil ontwerpers en kunstenaars inspireren die een onderzoek in de kunsten willen starten. Een onderzoek in de kunsten is niet iets dat je van bij het begin van je carrière als ontwerper of kunstenaar meteen volledig kan beheersen. Je eigen discipline aanleren en daarbinnen creatief werken zijn basisvereisten alvorens er sprake kan zijn van een onderzoek in de kunsten. Toch is het zinvol om je al in een vroeg stadium van je leerproces bewust te worden van een onderzoekende houding. Dat kan alleen maar door de verschillende onderdelen van het onderzoeksproces tijdens dit leerproces te expliciteren.
Dit boek geeft je als beginnende kunstenaar of ontwerper inzicht in het onderzoekproces in de kunsten, de redenen waarom een dergelijk onderzoek zinvol kan zijn, en voor wie. We gaan ook in op de specifieke plaats die deze vorm van onderzoek inneemt binnen de academische wereld. Al snel zal blijken hoe belangrijk jouw eigen praktijk als kunstenaar of ontwerper is, net als een grondige reflectie daarop. Dat zal de basis vormen voor een vorm van ervaringsleren die je toelaat om tot nieuwe kennis of betekenis te komen die gecommuniceerd kan worden. Het bewust aanleren van deze onderzoekende houding in een vroeg stadium van het leerproces zorgt ervoor dat je kan uitgroeien tot een onderzoeker in de kunsten die van betekenis is voor je eigen discipline, en wie weet ook voor de rest van de wereld.PXL-MA
Exclusivity as Inefficient Insurance
No full textIt is well established that an incumbent firm may use exclusivity contracts so as to monopolize an industry or deter entry. Such an anticompetitive practice could be tolerated if it were associated with sufficiently large efficiency gains, e.g. insuring buyers against price volatility. In this paper we study the trade-off between positive effects (risk sharing) and negative effects (exclusion) of exclusivity contracts. We revisit the seminal model of Aghion and Bolton (1987) under risk-aversion and show that although exclusivity contracts induce optimal risk-sharing, they can be used not only to deter the entry of a more efficient rival on the product market but also to crowd out financial investors willing to insure the buyer at competitive rates. We further show that in a world without financial investors, purely financial bilateral instruments, such as forward contracts, achieve optimal risk sharing without distorting product market outcomes. Thus, there is no room for an insurance defense of exclusivity contracts.exclusivity;contracts;monopolization;risk-aversion;risk-sharing;damages
Probing BERT for Ranking Abilities
No full textContextual models like BERT are highly effective in numerous text-ranking tasks. However, it is still unclear as to whether contextual models understand well-established notions of relevance that are central to IR. In this paper, we use probing, a recent approach used to analyze language models, to investigate the ranking abilities of BERT-based rankers. Most of the probing literature has focussed on linguistic and knowledge-aware capabilities of models or axiomatic analysis of ranking models. In this paper, we fill an important gap in the information retrieval literature by conducting a layer-wise probing analysis using four probes based on lexical matching, semantic similarity as well as linguistic properties like coreference resolution and named entity recognition. Our experiments show an interesting trend that BERT-rankers better encode ranking abilities at intermediate layers. Based on our observations, we train a ranking model by augmenting the ranking data with the probe data to show initial yet consistent performance improvements (The code is available at https://github.com/yolomeus/probing-search/ ).Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Web Information System

No full textBERT Rankers are Brittle: A Study using Adversarial Document Perturbations
No full textContextual ranking models based on BERT are now well established for a wide range of passage and document ranking tasks. However, the robustness of BERT-based ranking models under adversarial inputs is under-explored. In this paper, we argue that BERT-rankers are not immune to adversarial attacks targeting retrieved documents given a query. Firstly, we propose algorithms for adversarial perturbation of both highly relevant and non-relevant documents using gradient-based optimization methods. The aim of our algorithms is to add/replace a small number of tokens to a highly relevant or non-relevant document to cause a large rank demotion or promotion. Our experiments show that a small number of tokens can already result in a large change in the rank of a document. Moreover, we find that BERT-rankers heavily rely on the document start/head for relevance prediction, making the initial part of the document more susceptible to adversarial attacks. More interestingly, we find a small set of recurring adversarial words that when added to documents result in successful rank demotion/promotion of any relevant/non-relevant document respectively. Finally, our adversarial tokens also show particular topic preferences within and across datasets, exposing potential biases from BERT pre-training or downstream datasets.

Forged-GAN-BERT: Authorship Attribution for LLM-Generated Forged Novels
No full textThe advancement of generative Large Language Models (LLMs), capable of producing human-like texts, introduces challenges related to the authenticity of the text documents. This requires exploring potential forgery scenarios within the context of authorship attribution, especially in the literary domain. Particularly, two aspects of doubted authorship may arise in novels, as a novel may be imposed by a renowned author or include a copied writing style of a well-known novel. To address these concerns, we introduce Forged-GAN-BERT, a modified GAN-BERT-based model to improve the classification of forged novels in two data-augmentation aspects: via the Forged Novels Generator (i.e., ChatGPT) and the generator in GAN. Compared to other transformer-based models, the proposed Forged-GAN-BERT model demonstrates an improved performance with F1 scores of 0.97 and 0.71 for identifying forged novels in single-author and multi-author classification settings. Additionally, we explore different prompt categories for generating the forged novels to analyse the quality of the generated texts using different similarity distance measures , including ROUGE-1, Jaccard Similarity, Overlap Confident, and Cosine Similarity
