Multi‐Objective Optimisation Framework for Heterogeneous Federated Learning
ABSTRACT Federated learning is a distributed framework that trains a centralised model using data from multiple clients without transferring that data to a central server. Despite rapid progress, federated learning still faces several unsolved challenges. Specifically, communication costs and system heterogeneity, such as nonidentical data distribution,

Signal‐to‐noise and spatial resolution in in‐line imaging. 3. Optimization using a simple model
Geometrical magnification and X‐ray energy are optimized with respect to spatial resolution, contrast, noise, radiation dose and other image quality characteristics. The optimization is performed using a simple theoretical model of a homogeneous edge feature embedded in a bulk uniform sample, and the resulting generic analytical expressions for image ...

A Structural Model of Mortgage Offset Accounts in the Australian Housing Market*
I study a novel institutional feature of Australian housing markets: the widespread use of mortgage offset accounts. These accounts reduce mortgage interest costs and increase mortgage liquidity. I build a heterogeneous agent life‐cycle model of the Australian housing market to study who uses and benefits from these mortgage products.

ABSTRACT Most research questions in agricultural and applied economics are causal in nature: they study how changes in one or more variables (such as policies, prices or weather) affect one or more other variables (e.g., income, crop yields or pollution).

ABSTRACT We propose a tractable model of asymmetric platform oligopoly with logit demand in which users from two distinct groups are subject to within‐group and cross‐group network effects and decide which platform to join. We characterize the equilibrium when platforms manage user access by setting participation fees for each user group.

Why Is Exclusivity in Broadcasting Rights Prevalent and Why Does Simple Regulation Fail?
ABSTRACT Pay‐TV firms compete both downstream to attract viewers and upstream to acquire broadcasting rights. Because profits inherited from downstream competition satisfy a convexity property, allocating rights to the dominant firm maximizes the industry profit.

Efficient statistical inference of turning points in animal movement data
Abstract Recent years have seen a proliferation of high‐frequency animal movement data, often at greater than 1 Hz, allowing us to gain much greater insight into behaviour than with lower frequency data. In particular, it is becoming possible to detect the precise points at which animals are making decisions to turn, thus placing the idea that the ...

Farmers' pro‐social motivations and willingness‐to‐accept in markets with public goods
Abstract To explain how some farmers' decisions may diverge from profit‐maximization, we incorporate proactive social preferences for public goods in an expected utility framework, in addition to reactive risk preferences to uncertainty. We offer empirical evidence that proactive preferences influence farmers' decisions alongside reactive preferences ...
