RecipeMeta: Metapath-enhanced Recipe Recommendation on Heterogeneous Recipe Network
Recipe is a set of instructions that describes how to make food. It can help
people from the preparation of ingredients, food cooking process, etc. to
prepare the food, and increasingly in demand on the Web. To help users find the
vast amount of recipes on the Web, we address the task of recipe
recommendation. Due to multiple data types and relationships in a recipe, we
can treat it as a heterogeneous network to describe its information more
accurately. To effectively utilize the heterogeneous network, metapath was
proposed to describe the higher-level semantic information between two entities
by defining a compound path from peer entities. Therefore, we propose a
metapath-enhanced recipe recommendation framework, RecipeMeta, that combines
GNN (Graph Neural Network)-based representation learning and specific
metapath-based information in a recipe to predict User-Recipe pairs for
recommendation. Through extensive experiments, we demonstrate that the proposed
model, RecipeMeta, outperforms state-of-the-art methods for recipe
recommendation
An Evolutionary Algorithm to Mine High-Utility Itemsets
High-utility itemset mining (HUIM) is a critical issue in recent years since it can be used to reveal the profitable products by considering both the quantity and profit factors instead of frequent itemset mining (FIM) of association rules (ARs). In this paper, an evolutionary algorithm is presented to efficiently mine high-utility itemsets (HUIs) based on the binary particle swarm optimization. A maximal pattern (MP)-tree strcutrue is further designed to solve the combinational problem in the evolution process. Substantial experiments on real-life datasets show that the proposed binary PSO-based algorithm has better results compared to the state-of-the-art GA-based algorith

Intelligent Deep Fusion Network for Anomaly Identification in Maritime Transportation Systems
This paper introduces a novel deep learning architecture for identifying outliers in the context of intelligent transportation systems. The use of a convolutional neural network with decomposition is explored to find abnormal behavior in maritime data. The set of maritime data is first decomposed into similar clusters containing homogeneous data, and then a convolutional neural network is used for each data cluster. Different models are trained (one per cluster), and each model is learned from highly correlated data. Finally, the results of the models are merged using a simple but efficient fusion strategy. To verify the performance of the proposed framework, intensive experiments were conducted on marine data. The results show the superiority of the proposed framework compared to the baseline solutions in terms of several accuracy metrics.acceptedVersio
