Communicative Message Passing for Inductive Relation Reasoning
https://ojs.aaai.org/index.php/AAAI/article/view/16554

[ "Sijie Mai", "Shuangjia Zheng", "Yuedong Yang", "Haifeng Hu" ]
Relation prediction for knowledge graphs aims at predicting missing relationships between entities. Despite the importance of inductive relation prediction, most previous works are limited to a transductive setting and cannot process previously unseen entities. The recent proposed subgraph-based relation reasoning mode...

This paper proposes a new paradigm for learning a set of independent logical rules in disjunctive normal form as an interpretable model for classification. We consider the problem of learning an interpretable decision rule set as training a neural network in a specific, yet very simple two-layer architecture. Each neur...

Sequential recommender systems (SRS) have become a research hotspot in recent studies. Because of the requirement in capturing user's dynamic interests, sequential neural network based recommender models often need to be stacked with more hidden layers (e.g., up to 100 layers) compared with standard collaborative filte...

Dynamic load balancing lies at the heart of distributed caching. Here, the goal is to assign objects (load) to servers (computing nodes) in a way that provides load balancing while at the same time dynamically adjusts to the addition or removal of servers. Load balancing is a critical topic in many areas including clou...

In order for conversational AI systems to hold more natural and broad-ranging conversations, they will require much more commonsense, including the ability to identify unstated presumptions of their conversational partners. For example, in the command "If it snows at night then wake me up early because I don't want to ...

[ "Giulia Romano", "Gianluca Tartaglia", "Alberto Marchesi", "Nicola Gatti" ]
We study the problem of designing posted-price mechanisms in order to sell a single unit of a single item within a finite period of time. Motivated by real-world problems, such as, e.g., long-term rental of rooms and apartments, we assume that customers arrive online according to a Poisson process, and their valuations...

Online platforms sell advertisements via auctions (e.g., VCG and GSP auction) and revenue maximization is one of the most important tasks for them. Many revenue increment methods are proposed, like reserve pricing, boosting, coupons and so on. The novelty of coupons rests on the fact that coupons are optional for adver...

Modeling Voters in Multi-Winner Approval Voting

[ "Jaelle Scheuerman", "Jason Harman", "Nicholas Mattei", "K. Brent Venable" ]
In many real world situations, collective decisions are made using voting and, in scenarios such as committee or board elections, employing voting rules that return multiple winners. In multi-winner approval voting (AV), an agent submits a ballot consisting of approvals for as many candidates as they wish, and winners ...

Solution Concepts in Hierarchical Games Under Bounded Rationality With Applications to Autonomous Driving
https://ojs.aaai.org/index.php/AAAI/article/view/16715
https://ojs.aaai.org/index.php/AAAI/article/download/16715/16522
[ "Atrisha Sarkar", "Krzysztof Czarnecki" ]
With autonomous vehicles (AV) set to integrate further into regular human traffic, there is an increasing consensus of treating AV motion planning as a multi-agent problem. However, the traditional game theoretic assumption of complete rationality is too strong for the purpose of human driving, and there is a need for ...

An Analysis of Approval-Based Committee Rules for 2D-Euclidean Elections

[ "Michał T. Godziszewski", "Paweł Batko", "Piotr Skowron", "Piotr Faliszewski" ]
We study approval-based committee elections for the case where the voters' preferences come from a 2D-Euclidean model. We consider two main issues: First, we ask for the complexity of computing election results. Second, we evaluate election outcomes experimentally, following the visualization technique of Elkind et al....

Aggregating Binary Judgments Ranked by Accuracy

We revisit the fundamental problem of predicting a binary ground truth based on independent binary judgments provided by experts. When the accuracy levels of the experts are known, the problem can be solved easily through maximum likelihood estimation. We consider, however, a setting in which we are given only a rankin...

Participatory budgeting is a method used by city governments to select public projects to fund based on residents' votes. Many cities use participatory budgeting at a district level. Typically, a budget is divided among districts proportionally to their population, and each district holds an election over local project...
