Utilization and Synthesis of Symbolic World Models for Safe, Generalizable, and Efficient Action
… at learning to act in diverse environments. Model-based RL techniques have helped to ameliorate the dependence on large quantities of data that these models normally have. However, despite their flexibility, neural world models have several drawbacks. Symbolic world models, in comparison, are …

Neural World Models for Computer Vision
… in their environment by learning a mental model of the world through passive observation and active interaction. Their world model allows them to anticipate what might happen next and act accordingly with respect to an underlying objective. Such world models hold strong promises for …

LEARNING TO ACT FROM DIVERSE DATA SOURCES VIA WORLD MODELS
… learn generalist agents? I argue that learning world models that predict future outcomes of actions directly from image observations is a uniquely suitable approach for training generalizable agents. I will discuss how world models can enable powerful unsupervised exploration and how to use a …

Continuum: an architecture for user evolvable collaborative virtual environments
… Continuum's architecture supplies a world model and defines how to combine object state, behavior code, and resource data into this single shared structure. The system frees distributed users from the constraints of monolithic centralized virtual world architectures and instead allows …

British-to-Translocal Super-Club Culture (1991 – 2023): An Interpretation of a Life-World
The conceptualisation of the term ‘life-world’ (Lebenswelt) as devised by the German philosopher Edmund Husserl and father of transcendental phenomenology is a model for interpreting the subjective-to-intersubjective experiences of social life through the themes of empathy, intuition, temporality …

Intelligent execution monitoring and error analysis in planning involving processes
An intelligent agent, operating in an external world which cannot be fully described in its internal world model, must be able to monitor the success of a previously generated plan and to respond to any errors which may have occurred. The process of error analysis requires the ability to reason in …

From Subject to Object: Preservation and awareness of the vulnerable Cape Gannet
… and describes the concept of how an Ecocentric world model is possible by using architecture as a tool to achieve this. The relationship between humans and nature should be further investigated and developed as there is a current disconnect between these two. As a result, the natural environment …

Document retrieval based on a cognitive model of dialogue
… attempts to satisfy the user's needs from a model which it builds of the user's area of interest. This model is a subset of the program's "world model" - a database in the form of a network where the nodes represent concepts since various concepts have various degrees of similarities and …

Digital Filter Design and Synthesis Using High-level Modeling Tools
… Response (IIR) digital filters using high-level modeling tools. High-level modeling tools provide the ability to build and simulate ideal models. Once proper validation is complete on these ideal models, the user can then migrate to lower levels of abstraction until an actual real world model is …

Building World Models with Neural Physics
World models learn the dynamics of environments in a data-driven manner, enhancing performance and efficiency in downstream tasks such as control, design, recognition, and generation, thanks to cost-effective simulation and differentiability. A pre-trained world model should ideally (1) accurately …

Self-supervised Representation Learning in Computer Vision and Reinforcement Learning
… the exploration problem. The method employs a world model of the SSL latent space, and the prediction error of this model indicates novel states required to explore. It shows strong performance on exploration-hard benchmarks, especially on the notorious Montezuma's Revenge. Finally, we consider …

Exploration and mapping with mobile robots
Models of the environment are needed for a wide range of robotic <br>applications, from search and rescue to automated vacuum cleaning. <br>Learning maps has therefore been a major research focus in the <br>robotics community over the last decades. Robots that are able to <br>acquire an accurate …

Terrain and Adversary-Aware Autonomous Robot Navigation
… around it for intelligent navigation. From its world model of this environment, it generates a global plan for navigation from a position to a goal based on different factors. This research aims to implement autonomous robot navigation by learning terrain affordances: traversability (moving …

Model-based user interaction for accessing electronic news
… resolution of ambiguity and incompleteness. A model-based architecture is introduced in this thesis that provides a solution to these problems. The uniqueness of the solution is based on five interacting models: a language model responsible for the processing of individual user queries, a …

Smarter Agents for Agent-Based Models
Agent-based models (ABMs) are powerful tools for decision-making due to their ability to simulate systems with individual-level granularity. Recent advances have mitigated the computational costs of scaling ABMs to real-world population sizes; however, the potential of ABMs is also constrained by …

The drawing of bodies and things - Embodiment, observation, and representation
… concepts of the transparent self-model and internal simulated world-model as described by Thomas Metzinger. These readings are presented in dialogue with the practical body of work as well as analysis of other contemporary artists addressing embodiment, observational drawing, and …

Local-access generators for basic random graph models
… in a manner consistent with the random graph model and all previous choices. Local access generators can be useful when studying the local behavior of specific random graph models. Our goal is to design local access generators whose required resource overhead for answering each query is …

Convergence, coooperation, coordination : higher education governance and the Bologna process
… institutional convergence towards a perceived ‘world model’ of structure and governance. With the signing of the Bologna Declaration in 1999 (and its predecessor the Sorbonne Declaration in 1998), national ministries of education became the dominant agenda-setters for higher education, pursuing …
