Generative Recommenders (GRs) have recently emerged as promising alternatives to traditional Deep Learning Recommendation Models (DLRMs). Despite their potential, GRs remain computationally expensive in inference, exhibiting compute-bound characteristics similar to the prefill stage of Large Language Model (LLM) inference. Prefix caching can reduce redundant computation by reusing previously constructed KV caches. However, the unique properties of GRs, i.e., highly personalized user profiles and real-time item retrieval, make cache reuse across queries challenging, resulting in limited computational savings.

The volume of network traffic and elusiveness of modern cyber threats challenge the ability of cyber analysts to identify anomalous behavior in networks. In this work, we propose an autonomous agent to enhance analysts’ detection capabilities. To this end, we designed an agent to analyze feature-rich network traffic by autonomously executing the Data Analytic Development Process: (1) data engineering–prepares datasets, (2) feature engineering–selects the most representative features, (3) model engineering–chooses the best algorithm-feature combination, and (4) analytic deployment–applies the optimized analytic to the dataset and identifies anomalous behavior. We refer to this agent as an Autonomous Data Scientist (ADaS), utilizing reinforcement learning as an orchestrator to determine the optimal combination of features and unsupervised clustering algorithm. ADaS operates without labeled training data, and results on popular public datasets (NB15, IoT-23, and KDD’99) demonstrate high detection and low false alarm rates, making it reliable and novel for anomaly detection.

Skeleton-based action recognition has recently gained a lot of attention in computer vision. The previous skeleton-based datasets used sparse poses to represent the human body, which always leads to a large loss of human body detail information. Therefore, the previous skeleton-based methods generally performed worse than the image-based methods. In this paper, we propose a dense-pose-based action recognition dataset NTU-DensePose. This dataset automatically annotates 37,060 video samples with two dense poses, IUV equidistant annotation and IUV equivalent annotation. Each dense pose annotation contains more than 240 keypoints per instance. So the dense-pose-based action recognition method can capture more subtle details and predict human action more accurately than the previous skeleton-based methods. To the best of our knowledge, NTU-DensePose is the first dense-pose-based action recognition dataset.
