Model-based methods for recommender systems have been studied extensively in recent years. In with large corpus, however, the calculation cost learnt model to predict all user-item preferences is tremendous, which makes full corpus retrieval extremely difficult. To overcome barriers, models such as matrix factorization resort inner product form (i.e., preference of user, item latent factors) and indexes facilitate efficient approximate k-nearest neighbor searches. However, it still remains...

The effects of tensile uniaxial strain on the DC performance partially-depleted silicon-on-insulator n and p-channel MOSFETs as a function orientation gate length are reported. drain current n-MOSFETs increases for both longitudinal transverse orientations with respect to flow direction. In n-MOSFET, provides greater enhancement than strain. contrast, p-MOSFETs, decreases while current. magnitude fractional change in is reduced from 20 0.35 /spl mu/m. These phenomena consistent those bulk...
We explain how the manufacturing technology and reliability for advanced interconnects is impacted by choice of metallization interlayer dielectric (ILD) materials. The replacement aluminum alloys copper, as metal at 130-nm node, mandated notable changes in integration, metallization, patterning technologies. Those directly performance interconnect system. Although further improvement being pursued through utilizing progressively lower constant (low-k) ILD materials from one node to another,...
Text classification has gained booming interest over the past few years. As a simple, effective and nonparametric method, KNN method is widely used in document classification. However, uneven distribution training set will affect classified result negatively. Moreover, phenomenon of text very common documents on Web. To tackling this, this paper proposes an improved denoted by DBKNN. Experimental results show that DBKNN algorithm can better serve requests for large sets unevenly distributed...
Healthcare insurance frauds are causing millions of dollars public healthcare fund losses around the world in various ways, which makes it very important to strengthen management medical order guarantee steady operation funds. fraud detection methods can reduce funds and improve quality. Existing studies mostly focus on finding normal behavior patterns treat those violating as fraudsters. However, fraudsters often disguise themselves with some behaviors, such consistent behaviors when they...

We have developed a quantum anisotropic transport model for holes which, the first time, allows mobility to be studied under both uniaxial and arbitrary stress in PMOS inversion layers. The bandstructure of 2D gas is computed from 6-band dependent k.p Hamiltonian. Our unique momentum-dependent scattering also captures anisotropy scattering.

Large-scale industrial recommender systems are usually confronted with computational problems due to the enormous corpus size. To retrieve and recommend most relevant items users under response time limits, resorting an efficient index structure is effective practical solution. The previous work Tree-based Deep Model (TDM) \cite{zhu2018learning} greatly improves recommendation accuracy using tree index. By indexing in a hierarchy training user-node preference prediction model satisfying...
Recently, Graph Convolutional Network (GCN) based methods have become novel state-of-the-arts for Collaborative Filtering (CF) Recommender Systems. To obtain users' preferences over different items, it is a common practice to learn representations of users and items by performing embedding propagation on user-item bipartite graph, then calculate the preference scores representations. However, in most existing algorithms, user/item are generated independently target items/users. address this...
Does neural machine translation yield translations that are congenial with common sense? In this paper, we present a test suite to evaluate the commonsense reasoning capability of translation.

The effect of the constitutive response solder material on reliability large area joints within multilayered electronic packages is investigated subject to repeated thermal cycling. Solders that exhibit elastic and time-dependent plastic flow (viscoplasticity) were investigated. In accordance with traditional low-cycle fatigue models, exhibited extensive viscoplasticity cracking can be modelled following a Coffin-Manson approach for crack initiation. Subsequent growth was pronounced....
