AT4CTR: Auxiliary Match Tasks for Enhancing Click-Through Rate Prediction

AAAI 2024technical

Click-through rate (CTR) prediction is a vital task in industrial recommendation systems. Most existing methods focus on the network architecture design of the CTR model for better accuracy and suffer from the data sparsity problem. Especially in industrial recommendation systems, the widely applied…

On the Convergence of an Adaptive Momentum Method for Adversarial Attacks

AAAI 2024technical

Adversarial examples are commonly created by solving a constrained optimization problem, typically using sign-based methods like Fast Gradient Sign Method (FGSM). These attacks can benefit from momentum with a constant parameter, such as Momentum Iterative FGSM (MI-FGSM), to enhance black-box transf…

Locate, Refine and Restore: A Progressive Enhancement Network for Camouflaged Object Detection

IJCAI 2023poster

Camouflaged Object Detection (COD) aims to segment objects that blend in with their surroundings. Most existing methods mainly tackle this issue by a single-stage framework, which tends to degrade performance in the face of small objects, low-contrast objects and objects with diverse appearances. In…
