In this paper, we propose a talking face generation method that takes an audio signal as input and short target video clip reference, synthesizes photo-realistic of the with natural lip motions, head poses, eye blinks are in-sync signal. We note synthetic attributes include not only explicit ones such motions have high correlations speech, but also implicit poses weak correlation audio. To model complicated relationships among different audio, FACe Implicit Attribute Learning Generative...

The simultaneous recognition of multiple objects in one image remains a challenging task, spanning events the field such as various object scales, inconsistent appearances, and confused inter-class relationships. Recent research efforts mainly resort to statistic label co-occurrences linguistic word embedding enhance unclear semantics. Different from these researches, this paper, we propose novel Transformer-based Dual Relation learning framework, constructing complementary relationships by...

Few-shot class-incremental learning (FSCIL) aims at to classify new classes continually from limited samples without forgetting the old classes. The mainstream framework tackling FSCIL is first adopt cross-entropy (CE) loss for training base session, then freeze feature extractor adapt However, in this work, we find that CE not ideal session as it suffers poor class separation terms of representations, which further degrades generalization novel One tempting method mitigate problem apply an...

In quantum anomalous Hall (QAH) insulators, the interior is insulating but electrons can travel with zero resistance along one-dimensional (1D) conducting paths known as chiral edge channels (CECs). These CECs have been predicted to be confined 1D edges and exponentially decay in two-dimensional (2D) bulk. this Letter, we present results of a systematic study QAH devices fashioned bar geometry different widths under gate voltages. At charge neutral point, effect persists device width only...

Iceberg calving is a major component of the total mass balance Greenland ice sheet (GrIS). A century-long record icebergs comes from International Ice Patrol's (I48N) passing latitude 48° N, off Newfoundland. I48N exhibits strong interannual variability, with significant increase in amplitude over recent decades. In this study, we show, through combination nonlinear system identification and coupled ocean-iceberg modelling, that I48N's variability predominantly caused by fluctuation GrIS...
