1. 1. Environmental Modeling and Uncertainty

   Författare :Muhammad Sarfraz Iqbal; Dik van de Meent; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; QSAR; multimedia fate modeling; uncertainty analysis; probability bounds analysis; fuzzy arithmetic; chemical safety assessment; REACH;

   Sammanfattning : Environmental fate models are used to evaluate the fate and effects of chemicals for risk assessment. Fate models may be effective and low-cost substitutes for field measurements and are helpful to project future scenarios. LÄS MER

3. 2. Mining Futures : Predictions and Uncertainty in Swedish Mineral Exploration

   Författare :Tobias Olofsson; Patrik Aspers; Gholamreza Azarian; Trine Pallesen; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Uncertainty; Risk management; Sociology of the Future; Valuation; Justification; Mineral Exploration; Second Nature; Natural Resources; Sociologi; Sociology;

   Sammanfattning : Any forward-oriented enterprise must somehow manage the challenges posed by uncertainty and with its distant temporal horizons, high stakes, and low probability of success, mineral exploration is a good illustration of this general rule. Based on a combination of interviews, observations, and archival research, this thesis investigates how explorationists use predictions to manage the material complexities and the uncertainties that contribute to determining the future minability of mineral deposits.

4. 3. Robustness During Learning, Interaction and Adaptation for Autonomous Driving

   Författare :Hannes Eriksson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Reinforcement Learning; Epistemic Uncertainty; Uncertainty Quantification; Machine Learning; Autonomous Driving;

   Sammanfattning : In a sequential decision-making process, it is imperative to consider the potential risks of taking incorrect decisions throughout the whole process as all wrongdoings may not be possible to be remedied. This is particularly important when there are potentially catastrophic consequences. LÄS MER

5. 4. Guiding Concepts : Essays on Normative Concepts, Knowledge, and Deliberation

   Författare :Olle Risberg; Erik Carlson; Andrew Reisner; Wlodek Rabinowicz; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; action-guidance; adherence; all things considered ought; alternative normative concepts; conceptual engineering; debunking; deliberation; disagreement; epistemic pluralism; epistemology; ethics; external world skepticism; idealization; metaethics; meta-skepticism; moral skepticism; normativity; ought; reasons; response-dependence; uncertainty; Filosofi; Philosophy;

   Sammanfattning : This thesis addresses a range of questions about normativity, broadly understood. Recurring themes include (i) the idea of normative ‘action-guidance’, and the connection between normativity and motivational states, (ii) the possibility of normative knowledge and its role in deliberation, and (iii) the question of whether (and if so, how) normative concepts can themselves be evaluated.

7. 5. Decision-Making in Autonomous Driving using Reinforcement Learning

   Författare :Carl-Johan E Hoel; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo tree search; epistemic uncertainty; tactical decision-making; reinforcement learning; neural networks; aleatoric uncertainty; autonomous driving;

   Sammanfattning : The main topic of this thesis is tactical decision-making for autonomous driving. An autonomous vehicle must be able to handle a diverse set of environments and traffic situations, which makes it hard to manually specify a suitable behavior for every possible scenario. LÄS MER
