Towards Understanding Mixture of Experts in Deep Learning [article]

Zixiang Chen and Yihe Deng and Yue Wu and Quanquan Gu and Yuanzhi Li
2022 arXiv   pre-print
The Mixture-of-Experts (MoE) layer, a sparsely-activated model controlled by a router, has achieved great success in deep learning. However, the understanding of such architecture remains elusive. In this paper, we formally study how the MoE layer improves the performance of neural network learning and why the mixture model will not collapse into a single model. Our empirical results suggest that the cluster structure of the underlying problem and the non-linearity of the expert are pivotal to

Yet with the MoE layer, by choosing the experts as two-layer nonlinear convolutional neural networks (CNNs), we show that the problem can be learned successfully. Furthermore, our theory shows that the router can learn the cluster-center features, which helps divide the input complex problem into simpler linear classification sub-problems that individual experts can conquer. To our knowledge, this is the first result towards formally understanding the mechanism of the MoE layer for deep learning.

2009 2009 Design, Automation & Test in Europe Conference & Exhibition  
Packet-switched interconnect fabric is a promising on-chip communication solution for many-core architectures. It offers high throughput and excellent scalability for on-chip data and protocol transactions. The main problem posed by this communication fabric is the potentially-high and nondeterministic network latency caused by router data buffering and resource arbitration. This paper describes a new method to minimize onchip network latency, which is motivated by the observation that only a
more » ... all percentage of on-chip data and protocol traffic is latency-critical. Existing work focusing on minimizing average network latency is thus suboptimal. Such techniques expend most of the design, area, and power overhead accelerating latency-noncritical traffic for which there is no corresponding application-level speedup. We propose run-time techniques that identify latency-critical traffic by leveraging network data-transaction and protocol information. Latency-critical traffic is permitted to bypass router pipeline stages and latency-noncritical traffic. These techniques are evaluated via a router design that has been implemented using TSMC 65 nm technology. Detailed network latency simulation and hardware characterization demonstrate that, for latencycritical traffic, the proposed solution closely approximates the ideal interconnect even under heavy load while preserving throughput for both latency-critical and noncritical traffic.

Hulin Wu, Yihe Wang, Lin Xiang, Guanlin Song, Zhiwen Xie
2021 Coatings  
Transition-metal nitride coating used to protect the electronic connector devices in marine environment is required to have high electrical conductivity and good corrosion resistance. This study synthesized a novel CrN–Pt coating with a dense growth texture. Pt addition induced a pronounced increase in electrical conductivity and corrosion resistance. The resistivity decreased from 0.0149 Ohm·cm in the CrN coating to 0.000472 Ohm·cm in the CrN–Pt coating, while the corrosion current density

2021 Water  
Biological processes have high removal efficiencies and low operational costs, but the secondary effluent of coking wastewater (CWW), even at a low concentration, is difficult for microorganisms to degrade directly. In this study, glucose was used as a carbon source and co-metabolic substrate for microbial acclimation in order to enhance the advanced treatment of coking wastewater (CWW). The removal performance of the pollutants, especially recalcitrant compounds, was studied and the changes in

The effect of glucose addition on the secondary biochemical effluent of coking wastewater (SBECW) treatment by the acclimated sludge was further studied by a comparison between the performance of two parallel reactors seeded with the acclimated sludge. Our results showed that the concentrations of chemical oxygen demand (COD), total organic carbon (TOC), and UV absorption at 254 nm (UV254) of the wastewater decreased in the acclimation process. Refractory organic matter, such as polycyclic aromatic hydrocarbons and nitrogen-containing heterocyclics, in the SBECW was effectively degraded by the acclimated sludge. High-throughput sequencing revealed that microbes with a strong ability to degrade recalcitrant compounds were enriched after acclimation, such as Thauera (8.91%), Pseudomonas (3.35%), and Blastocatella (10.76%). Seeded with the acclimated sludge, the reactor with the glucose addition showed higher COD removal efficiencies than the control system without glucose addition (p < 0.05). Collectively, glucose addition enhanced the advanced treatment of coking wastewater (CWW).

Multiferroic Properties of Nanopowder-Synthesized Ferroelectric-Ferromagnetic 0.6BaTiO3-0.4NiFe2O4Ceramic

Xinye Xu, Zheng Wu, Yanmin Jia, Weijian Li, Yongsheng Liu, Yihe Zhang, A'Xi Xue
2015 Journal of Nanomaterials  
Multiferroic 0.6BaTiO3-0.4NiFe2O4dense nanoceramic composites were synthesized via a powder-in-sol precursor hybrid chemical synthesis route and a ceramic sintering process. At the measured frequency range (1 kHz~1 MHz), the relative dielectric constant is 150~1670 and the dielectric loss is 0.05~0.70. The composite ceramic showed obvious coexistence of ferroelectric and ferromagnetic phases. With the increase of temperature, the saturation ferromagnetic magnetization decreases, while the ferroelectric polarization increases.

2015 Scientific Reports  
Ecological conservation and restoration are necessary to mitigate environmental degradation problems. China has taken great efforts in such actions. To understand the ecological transition during 2000-2010 in China, this study analysed trends in vegetation change using remote sensing and linear regression. Climate and socioeconomic factors were included to screen the driving forces for vegetation change using correlation or comparative analyses. Our results indicated that China experienced both

Socioeconomic factors, such as human populations and economic production, were the most significant factors for vegetation change. Nature reserves have contributed slightly to the deceleration of vegetation browning and the promotion of greening; however, a large-scale conservation approach beyond nature reserves was more effective. The effectiveness of the Three-North Shelter Forest Program lay between the two above approaches. The findings of this study highlighted that vegetation trend detection is a practical approach for large-scale ecological transition assessments, which can inform decision-making that promotes vegetation greening via proper socioeconomic development and ecosystem management.

The fluoride sorption process was well fitted to the pseudo-second-order rate kinetics and pore diffusion models. The optimum fluoride removal was observed between pH range 3 and 4 and the adsorption capacity for fluoride by Zr-modified RMPM was 0.6 mg/g. Results from this study demonstrated potential use of Zr-modified RMPM in defluoridation of drinking water.

Rong Yang, Linpeng Yao, Chengli Du, Yihe Wu
2021 Annals of Translational Medicine  
Atherosclerosis leads to the occurrence of cardiovascular diseases. However, the molecular mechanisms that contribute to atherosclerotic plaque rupture are incompletely characterized. We aimed to identify the genes related to atherosclerotic plaque progression that could serve as novel biomarkers and interventional targets for plaque progression. The datasets of GSE28829 in early vs. advanced atherosclerotic plaques and those of GSE41571 in stable vs. ruptured plaques from Gene Expression

In addition, we used quantitative reverse transcription polymerase chain reaction (qRT-PCR) to verify the expression level of core genes in a mouse atherosclerosis model. There were 29 common differentially expressed genes (DEGs) between the GSE28829 and GSE41571 datasets, and the DEGs were mainly enriched in the chemokine signaling pathway and the Staphylococcus aureus infection pathway (P<0.05). We identified 6 core genes (FPR3, CCL18, MS4A4A, CXCR4, CXCL2, and C1QB) in the protein-protein interaction (PPI) network, 3 of which (CXCR4, CXCL2, and CCL18) were markedly enriched in the chemokine signaling pathway. qRT-PCR analysis showed that the messenger RNA levels of two core genes (CXCR4 and CXCL2) increased significantly during plaque progression in the mouse atherosclerosis model. In summary, bioinformatics techniques proved useful for the screening and identification of novel biomarkers of disease. A total of 29 DEGs and 6 core genes were linked to atherosclerotic plaque progression, in particular the CXCR4 and CXCL2 genes.
