Intraday Functional PCA Forecasting of Cryptocurrency Returns

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT We study the functional PCA (FPCA) forecasting method in application to functions of intraday returns on Bitcoin. We show that improved interval forecasts of future return functions are obtained when the conditional heteroscedasticity of return functions is taken into account.

Ultrafast in‐memory computing and highly efficient deep neural networks driven by phase‐change memory materials with partially amorphous state transitions

open access: yesInfoScience, EarlyView.
This work addresses challenges including the nonlinear weight‐conductance update and the trade‐off between increasing melting uniformity and reducing solid‐to‐liquid transition time. It utilizes all four melting states to create an integrated framework for attaining in‐memory computing and deep neural network applications. The framework achieves a near‐

Promise‐Keeping Reputations in an Investment Game: An Experimental Investigation

open access: yesInternational Studies of Economics, EarlyView.
ABSTRACT We design a controlled laboratory experiment to mitigate moral hazard problems in livestream shopping when sellers make promises to buyers. In our experiment, the promise‐keeping reputation mechanism allows sellers to send promises to buyers while buyers can observe the sellers' historical promise‐keeping records. Results demonstrate that bare
