Customer service employees are generally advised to express positive emotion during their interactions with customers. The rise and maturity of artificial intelligence (AI)–powered conversational…
In this article, a novel Bayes-Adam-based multiple-input multiple-output (MIMO) equalizer was proposed and experimentally demonstrated for an orbital angular momentum (OAM) mode-division multiplexe…
A microfiber Bragg grating (MFBG) bonded using tapered cantilever was designed to improve ultrasonic sensitivity, and was investigated using experimental, theoretical, and numerical methods. The ul…
We study an inventory system with multiple supply sources and expediting options. The replenishment lead times from each supply source are stochastic, representing congestion and disruption. We con…
We propose scene graph auto-encoder (SGAE) that incorporates the language inductive bias into the encoder-decoder image captioning framework for more human-like captions. Intuitively, we humans use…
With the need for further increase in communication capacity, mode division multiplexing (MDM) technology has become a more promising technical approach. In this paper, we perform an experimental d…
We study deterministic fluid approximation models of parallel service systems with a fixed set of servers, operating under first come first served (FCFS) policy, when the service time distributions…
We study a buyer’s problem of auditing suppliers within an existing network to ensure social responsibility compliance. The buyer suffers economic damages if a violation at a supplier is exposed …
With the maturity of visual detection techniques, we are more ambitious in describing visual content with open-vocabulary, fine-grained and free-form language, i.e., the task of image captioning. I…
Grounding natural language in images, such as localizing “the black dog on the left of the tree”, is one of the core problems in artificial intelligence, as it needs to comprehend the fine-grai…
