Adversarial Attacks on Content-Based Filtering Journal Recommender Systems

Recommender systems are very useful for people to explore what they really need.Academic papers are important achievements for researchers and they often have a great deal of choice to submit their papers.In order to improve the efficiency of selecting the most suitable journals for publishing their works,journal recommender systems(JRS)can automatically provide a small number of candidate journals based on key information such as the title and the abstract.However,users or journal owners may attack the system for their own purposes.In this paper,we discuss about the adversarial attacks against content-based filtering JRS.We propose both targeted attack method that makes some target journals appear more often in the system and non-targeted attack method that makes the system provide incorrect recommendations.We also conduct extensive experiments to validate the proposed methods.We hope this paper could help improve JRS by realizing the existence of such adversarial attacks.

Using agrophotovoltaics to reduce carbon emissions and global rural poverty

Poverty-alleviation programs using solar energy(PAPSE)are poised to unlock unprecedented capital investments with significant potential to reconcile the energy–poverty–climate nexus.1 These programs are economically feasible because the costs of generating renewable energy have declined precipitously over the past decade;between 2010 and 2019,solar photovoltaiccosts decreased by 82%.Furthermore,the number of annual equivalent-use hours of sunlight in most countries exceeds 1200,meaning that PAPSE approaches are feasible in many places and can be undertaken independently from the power grid.
