Exploration and Exploitation: A Study on Sample Efficiency in Reinforcement Learning With Multifaceted Curiosity Rewards and Adaptive Experience Replay Utilisation in Sparse Reward Environments

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT In recent years, the widespread application of deep reinforcement learning (DRL) in autonomous systems has highlighted the importance of achieving high sample efficiency under sparse reward conditions. To improve sample efficiency in sparse reward environments, this paper proposes a reinforcement learning framework built upon the Soft Actor ...

Addressing Long‐Tailed Drug–Drug Interactions Through Minimisation of Predictive Uncertainty and Loss Sharpness

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Drug–Drug Interaction (DDI) prediction is critical for ensuring patient safety, particularly under long‐tailed distributions, where frequent (head) interactions dominate whereas rare (tail) interactions remain underrepresented. Conventional loss functions such as cross‐entropy often tend to overfit head classes while they underperform on rare ...

The Mysterious Stranger and Modern Enchantment

The British Journal of Sociology, EarlyView.
ABSTRACT Sociological accounts of modernity have long emphasized rationalization, alienation, and the attenuation of affective intensity. While these diagnoses capture crucial dynamics of modern social order, they leave underexplored a persistent and generative dimension of social life: enchantment.

Adaptive Hashing

CoRR
Hash tables are ubiquitous, and the choice of hash function, which maps a key to a bucket, is key for their performance. We argue that the predominant approach of fixing the hash function for the lifetime of the hash table is suboptimal and propose adapting it to the current set of keys.

The effect of nearby listings on house sale prices in Sydney: A spatio‐temporal regularization approach

Real Estate Economics, EarlyView.
Abstract We estimate the price impact of very nearby concurrently listed properties in the Sydney housing market and assess their competition effects. We apply a hedonic model with spatiotemporal effects regularized via a graph Laplacian prior at the month‐by‐SA2 regional level to seven SA4 subregions of metropolitan Sydney. The model structure enables

Preserving evidence integrity in full file system extractions: Assessing hash inconsistencies and potential solutions

Journal of Forensic Sciences, EarlyView.
Abstract Smartphone manufacturers' enhanced privacy and security measures, such as File‐Based Encryption (FBE), have disrupted traditional data extraction techniques, necessitating the adoption of Full File System Extraction (FFS). FFS requires booting a smartphone, decrypting its UserData partition, and accessing files individually, a process that ...

Revocable policy-based chameleon hash using lattices

Journal of Mathematical Cryptology
A chameleon hash function is a type of hash function that involves a trapdoor to help find collisions, i.e., it allows the rewriting of a message without modifying the hash.

Interactional privilege of violence: Status and interaction in the street field

Criminology, EarlyView.
Abstract Criminologists have long described and theorized the relationship between status, respect, and violence within urban communities. Although this finding is generally accepted within criminology, ethnographic empirical illustrations of this phenomenon are sparse.

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Vertical coordination in agri‐food supply chain and blockchain: A proposed framework solution for Vietnamese cashew nut business

Regional Science Policy &Practice, EarlyView., 2022
Abstract The agri‐food supply chain has been a popular research topic in recent years. The combination of a demand for products of high quality and safety standards and the increasing number of stakeholders in supply chain networks has required the agri‐food business to transform from vertically integrated to vertically operated supply chain networks ...
