Tokenizing time series data and treating it like a language enables a model whose zero-shot performance matches or exceeds that of purpose-built models. Update: Amazon scientists how now released the training code for Chronos, which is available on GitHub.

SIGIR 20242024Evaluating a new ranking policy using data logged by a previously deployed policy requires a counterfactual (off-policy) estimator that corrects for presentation and selection biases. Some estimators (e.g., the position-based model) perform this correction by making strong assumptions about user behavior, which can lead to high bias if the assumptions are not met. Other estimators (e.g., the item-position

Extracting product attributes from images involves classifying subtle differences between similar objects. Visual Transformers (ViT) are powerful but usually supervised, while e-commerce labels are noisy or expensive to clean. In this work, we demonstrate the benefit for e-commerce of semi-supervised techniques like Semi-ViT, a ViT model fine-tuned with unlabeled data. We demonstrate that when Semi-ViT

ICCSM 20242024Security Attacks (SA) refer to a kind of malicious activity in which SA causes information destruction. Existing works have failed to concentrate on various attacks that limit the model’s performance. Therefore, this paper presents Cumulative Distribution-GELU-Convolutional Neural Network (CD-GELU-CNN) and Feature Map-based-Lattice Rainbow Quantum Cryp-tography (FMLRQC) techniques for SA detection and prevention
