The exploration-exploitation trade-off in sequential decision making problems
… of actions. Common to such problems is the exploration-exploitation trade-off, where an agent must choose between the action expected to yield the best reward (exploitation) or trying an alternative action for potential future benefit (exploration). The main focus of this thesis is to …

An exploration account of media multitasking: The exploration-exploitation model to explain media multitasking behavior
This study provides an Exploration-Exploitation Model of media multitasking, suggesting that people’s decision tendency toward exploration activates multitasking behavior, while a tendency toward exploitation keeps people media single-tasking. Moreover, I also propose that intrinsic motivation …

Information selection in intelligence processing
… for delivery to intelligence analysts, as an exploration-exploitation problem: the processor has to choose between exploring for new sources of relevant information and exploiting known sources. To address the exploration-exploitation problem, we develop a mathematical model of the processor's …

Petroleum, alcohol, and energy substitution in Brazil: Theoretical and empirical issues
… by controversy in Brazil. Issues related to exploration, exploitation and import of crude have received special attention by Brazilian decision makers. In the past decade, an additional relevant issue was brought into play by the oil crisis. An import substitution program for energy was …

A modified experts algorithm : using correlation to speed convergence with very large sets of experts
This paper discusses a modification to the Exploration-Exploitation Experts algorithm - (EEE). The EEE is a generalization of the standard experts algorithm which is designed for use in reactive environments. In these problems, the algorithm is only able to learn about the expert that it follows at …

Genetic Variation in Neurotransmitter Receptors Generates Behavioral Diversity
… is the existence of different thresholds for exploration—exploitation tradeoffs: some strains decide to exploit resources more thoroughly, while others decide to abandon resources earlier and explore other options. Using quantitative genetic tools I have found that genetic variation in the …

Multi-Agent LLMs for Adaptive Acquisition in Bayesian Optimization
… statistics (e.g., mean/variance), which can make exploration–exploitation trade-offs inflexible and sensitive to hyperparameters such as the UCB β term. These limitations become acute in higher-dimensional or irregular landscapes relevant to engineering design. We propose an agentic LLM framework …

Risk-averse multi-armed bandits and game theory
… the Blind GB-PANDAS algorithm that utilizes an exploration-exploitation scheme to load balance incoming tasks on servers in an online fashion. We prove that Blind GB-PANDAS is throughput optimal, i.e. it stabilizes the system as long as the task arrival rates are inside the capacity region. The …

Improved worst-case regret bounds for randomized least-squares value iteration
This work studies regret minimization with randomized value functions in reinforcement learning. In tabular finite-horizon Markov Decision Processes, we introduce a clipping variant of one classical Thompson Sampling (TS)-like algorithm, randomized least-squares value iteration (RLSVI). Our …

Innovation strategies of New Technology-Based Firms for managing crises: reconciling short-term survival and long-term success. The case of gene therapy pioneers
… explorative and exploitative innovation (the exploration/exploitation or ambidexterity concept) and may do so through intra- or inter-organisational modes (the internal and Open Innovation concept). Both concepts are well known for their critical role during crises and for their differing …

Essays on the Strategic Implications of Marketing Capabilities: Marketing Exploration and Exploitation
My dissertation examines how exploitation and exploration capabilities impact organizational performance for competitive advantage. The first essay reviews previous empirical, simulation, and theoretical studies to provide a synopsis and quantitative assessment of previous empirical research. The …

Foreign Direct Investment and Environmental Rights Protection in Nigeria. Towards a Balance in the Regulatory Framework in the Oil and Gas Industry
… These challenges arise from the impacts of oil exploration, exploitation, and the over-utilisation of resources that bear on the environmental rights of the host communities. The research discusses these impacts on the right to the environment and the hindrances which impede its realization and …

Assessment of Reinforcement Learning Algorithms for Nuclear Power Plant Fuel Optimization
… the stability of the learning. But also an exploration/exploitation trade-off that manifests through different parameters such as the number of loading patterns seen by the agents per episode, the number of samples collected before a policy update nsteps , and an entropy factor ent_coef that …

An improved artificial bee colony algorithm for training multilayer perceptron in time series prediction
… improved algorithms were used to increase the exploration, exploitation and keep them balance for getting optimal results for a given task. Furthermore, here these algorithms used to train the MLP on two tasks; the seismic event's prediction and Boolean function classification. The simulation …

The effect of Trust on Innovation: A Behavioral Investigation
… a novel approach. The design draws on the exploration-exploitation dilemma described by March (1991), whereby firms must decide whether to exploit existing capabilities or explore new solutions. Our dissertation is composed of three chapters. In the first chapter we review the possible …

ONLINE LEARNING METHODS FOR DIGITAL MARKETS
… devising ad hoc solutions to address the exploration/exploitation dilemma in various types of environments. In Chapter 3, we present an analysis of transparency in repeated first-price auctions. Here, the learner participates in a sequence of first-price auctions to win objects whose exact …

Media exposure, policy agenda setting and risk communication in Sub-Saharan Africa: a case study of Nigeria's Niger Delta region
… in the aforementioned states due to oil exploration / exploitation and underdevelopment. Findings from this research revealed that the Nigerian media-policy-public agendas face specific problems in influencing one another on environmental risk issues and other facet of the conflict in …

An artificial experimenter for automated response characterisation
… and a Bayesian surprise method for managing the exploration{exploitation trade-off between new feature discovery and hypothesis disproving. The techniques are validated through a laboratory trial where successful biological characterisation has been shown

ONLINE RESOURCE ALLOCATION AND ITS APPLICATIONS
… MAB is a classical problem that exemplifies the exploration-exploitation trade-off. Standard formulations of MAB do not take into account risk. In online decision-making systems, risk is a primary concern. In this regard, the mean-variance and CVaR risk measures are the most common objective …
