2020

In the traditional Proof of Stake (PoS), the share of the currency owned by the node, that is, the share of the equity, determines the probability that the node is selected as the representative node. …

Efficient semi-quantum secret sharing protocol using single particles

2023 · Chinese Physics B

Semi-quantum secret sharing (SQSS) is a branch of quantum cryptography which only requires the dealer to have quantum capabilities, reducing the difficulty of protocol implementation. However, the efficiency of the SQSS protocol still needs to …

Chaotic Time Series Prediction of Echo State Network Based on Memristor

2024

In this paper, we proposed a new echo state network (ESN) model, namely echo state network based on memristor (memristor-ESN). It improve the memory function of the reservoir and the prediction performance of the ESN. …

STILE: Exploring and Debugging Social Biases in Pre-trained Text Representations

2024

The recent success of Natural Language Processing (NLP) relies heavily on pre-trained text representations such as word embeddings. However, pre-trained text representations may exhibit social biases and stereotypes, e.g., disproportionately associating gender with occupations. Though …
