Self-Domain Adaptation for Face Anti-Spoofing
Although current face anti-spoofing methods achieve promising results under
intra-dataset testing, they suffer from poor generalization to unseen attacks.
Most existing works adopt domain adaptation (DA) or domain generalization (DG)
techniques to address this problem. However, the target domain is often unknown
during training which limits the utilization of DA methods. DG methods can
conquer this by learning domain invariant features without seeing any target
data. However, they fail in utilizing the information of target data. In this
paper, we propose a self-domain adaptation framework to leverage the unlabeled
test domain data at inference. Specifically, a domain adaptor is designed to
adapt the model for test domain. In order to learn a better adaptor, a
meta-learning based adaptor learning algorithm is proposed using the data of
multiple source domains at the training step. At test time, the adaptor is
updated using only the test domain data according to the proposed unsupervised
adaptor loss to further improve the performance. Extensive experiments on four
public datasets validate the effectiveness of the proposed method.Comment: Camera Ready, AAAI 202
Bioconversion of rice straw agro-residues by \u3cem\u3eLentinula edodes\u3c/em\u3e and evaluation of non-volatile taste compounds in mushrooms
Rice straw was substituted for sawdust at five different ratios of 0, 20%, 40%, 60%, and 80% (Control, RS20, RS40, RS60 and RS80, respectively) to obtain five kinds of Lentinula edodes. The effects of adding cropped rice straw to substrate formulas on the proximate composition and non-volatile taste compounds in mushrooms were investigated. The control group had the highest level of MY and BE among the five formulations. The protein levels in mushrooms decreased with the addition of rice straw and the ash levels increased. We found that trehalose, mannitol, and arabitol were the main soluble sugars in the five kinds of mushrooms. The contents of total free amino acids varied from 16.29 to 24.59 mg/g and the highest level of free amino acids was found in mushrooms cultivated from RS20 and RS40. Moreover, the addition of rice straw improved the contents of monosodium glutamate (MSG)-like amino acids in mushrooms. The 5′-Nucleotide levels ranged from 1.66 to 4.48 mg/g and equivalent umami concentration (EUC) value increased with the addition of rice straw. Our results suggest that rice straw is a potential substitute for sawdust to cultivate L. edodes with more non-volatile taste compounds
{N,N-Dimethyl-N′-[phenyl(2-pyridyl)methylene]ethane-1,2-diamine-κ3 N,N′,N′′}dithiocyanato-κN,κS-copper(II)
In the title complex, [Cu(NCS)2(C16H19N3)], the CuII atom is coordinated by a total of four N atoms; three from one tridentate Schiff base ligand and one from one of the NCS− ions. The S atom from the other NCS− ion completes the distorted square-pyramidal coordination
