Measure‐valued processes for energy markets

open access: yesMathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

open access: yesMathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Teleosemantics for neural word embeddings

open access: yesMind &Language, EarlyView.
This paper applies a consumer‐based teleosemantic framework to give a detailed analysis of a particular algorithm for generating word embeddings. In the process, it addresses several of the challenges facing teleosemantic approaches to artificial neural networks.

Mixed‐vertebrate pollination traits and pollinators of Haageocereus acranthus (Cactaceae) in a lomas desert ecosystem of coastal Peru

open access: yesPlant Biology, EarlyView.
In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.

Knowledge Spillover, Trust, Effort, and Error Exposure in Peer‐Assisted Learning

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Peer‐assisted learning has the potential to improve learning in academic settings and beyond. However, the cognitive and motivational mechanisms of learning through interaction with other learners are not fully understood. Here, we present an empirical study in which we compare a peer‐assisted learning condition with two individual learning ...
