Understanding the anisotropic response of -GaO to ion implantation
Duarte Magalhães Esteves, Ru He, Sérgio Magalhães +8
While -GaO is considered a promising wide bandgap semiconductor, the impact of ion-induced defect formation and anisotropic elasticity remains poorly understood. Here,…
Progressively Stacking 2.0: A Multi-stage Layerwise Training Method for BERT Training Speedup
Cheng Yang, Shengnan Wang, Chao Yang +3
Pre-trained language models, such as BERT, have achieved significant accuracy gain in many natural language processing tasks. Despite its effectiveness, the huge number of paramete…
Bounded-Compute Multimodal Regression for Product-Rating Prediction
William Leach, Ru He, Sizhuo Ma +4
Vision-language models (VLMs) are increasingly attractive for multimodal quality assessment, but their default reliance on autoregressive text generation and dynamic visual process…
Bayesian Model Averaging Using the k-best Bayesian Network Structures
Jin Tian, Ru He, Lavanya Ram
We study the problem of learning Bayesian network structures from data. We develop an algorithm for finding the k-best Bayesian network structures. We propose to compute the poster…
GUIM -- General User and Item Embedding with Mixture of Representation in E-commerce
Chao Yang, Ru He, Fangquan Lin +3
Our goal is to build general representation (embedding) for each user and each product item across Alibaba's businesses, including Taobao and Tmall which are among the world's bigg…
Computing Posterior Probabilities of Structural Features in Bayesian Networks
Jin Tian, Ru He
We study the problem of learning Bayesian network structures from data. Koivisto and Sood (2004) and Koivisto (2006) presented algorithms that can compute the exact marginal poster…
