Federated learning is a distributed, on-device computation framework that enables training global models without exporting sensitive user data to servers. In this work, we describe methods extend the federation evaluate strategies for personalization of models. We present tools analyze effects and conditions under which yields desirable report on our experiments personalizing language model virtual keyboard smartphones with population tens millions users. show significant fraction users...
Rational cropping maintains high soil fertility and a healthy ecosystem. Soil microorganism is the controller of fertility. Meanwhile, microbial communities also respond to different patterns. The mechanisms by which biotic abiotic factors were affected sequences remain unclear in major grain-producing regions northeastern China. To evaluate effects under conventional fertilization practices on properties, communities, crop yield, six types plant systems performed, including soybean...
Until recently, brand identities were built by firms via image advertising. However, the flourishing consumer communication weakened firms' grip on their brands. The interaction between advertising and communications joint impact identity is focal point of this paper. We present a model in which preference for functional attributes may correlate with they desire to project themselves. This correlation known firm but not consumers. Both consumers can communicate desired identity, although...
Agricultural productive services are an important means to achieve effective allocation of regional resources and play role in ensuring food security improving farmers’ welfare. However, the development process agricultural still faces problems such as large differences service levels different segments low participation rates full service. In order investigate influential paths rate farmers full-service process, this study takes maize northeast China research object. Based on 937 survey...
Nitrofuran (NF) is a class of broad-spectrum antibiotics that are used illegally in animal feeding. NF and its metabolites have proven to pose potential risk human health. To address the current analytical needs quantify low levels foods, sensitive method was developed for simultaneous detection four fish products by an ultraperformance liquid chromatography-diode array detector (UPLC-DAD). With 2-nitrobenzaldehyde (2-NBA) as derivatizing reagent, were hydrolyzed derivatized under assistance...
One of the characteristics fashion marketplace is unpredictability and apparent randomness hits. Another one information asymmetry among consumers. In this paper, we consider as a means consumers use to signal belonging higher social rank propose an analytical model hits in presence competition who can coordinate on which product use. We show that, consistent with observed market phenomenon, equilibrium, consumer coordination involves randomization between products chosen, i.e., Analyzing...
A well-established phenomenon of consumer buying behavior is that consumers evaluate prices relative to a reference point and exhibit loss aversion; i.e., their propensity buy more negatively affected by above the than it positively below point. The objective this paper analytically examine how competitive strategy profitability firms are presence aversion in price dimension. Although we assume increases search for lower prices, find does not necessarily lead or profits when compete over...
Consumer showrooming – the behavior of examining a product in brick-andmortar store and later buying it from an online retailer is seen as major threat to brick-and-mortar retailers. To combat showrooming, Best Buy announced price-matching policy 2012 compete with In this paper, we examine impact Buy's on price competition between Amazon across wide variety categories. We empirically explore Amazon's pricing patterns using unique datasets collected different sources, find robust results that...
Original design manufacturers (ODM) is a new form of global outsourcing. Traditional outsourcing only transfers the production product from brands to manufacturers. An ODM, in contrast, not manufactures for brand, but also designs product. Using an analytical model, we investigate strategic decisions firms. Two firms competing horizontally differentiated market decide whether products by themselves or outsource ODM. We consider two different channel structures -- one which each firm partners...
As urbanization accelerates in China, more and rural elders are moving to cities live with their children. However, they face challenges overcoming cultural, social, economic disparities maintaining health urban life, is important human capital that may have a significant impact on the adaptation of elderly migrants (REMs). Based 2018 China Health Retirement Longitudinal Study (CHARLS), this paper constructs an indicator system measure level REMs. The REMs studied depth, how better help them...
In this paper, a generalized Shannon-McMillan theorem for the nonhomogeneous Markov chains indexed by an inflnite tree which has uniformly bounded degree is discussed constructing nonnegative mar- tingale and analytical methods. As corollaries, some Shannon-Mcmillan theorems homoge- neous chain are obtained. Some results have been obtained extended.
