Conversational Recommender System [article]

Yueming Sun, Yi Zhang
2018 arXiv   pre-print
A personalized conversational sales agent could have much commercial potential. E-commerce companies such as Amazon, eBay, JD, Alibaba etc. are piloting such kind of agents with their users. However, the research on this topic is very limited and existing solutions are either based on single round adhoc search engine or traditional multi round dialog system. They usually only utilize user inputs in the current session, ignoring users' long term preferences. On the other hand, it is well known

In this work, we propose to integrate research in dialog systems and recommender systems into a novel and unified deep reinforcement learning framework to build a personalized conversational recommendation agent that optimizes a per session based utility function.

Towards Concolic Testing for Hybrid Systems [article]

Pingfan Kong, Yi Li, Xiaohong Chen, Jun Sun, Meng Sun, Jingyi Wang
2016 arXiv   pre-print
Hybrid systems exhibit both continuous and discrete behavior. Analyzing hybrid systems is known to be hard. Inspired by the idea of concolic testing (of programs), we investigate whether we can combine random sampling and symbolic execution in order to effectively verify hybrid systems. We identify a sufficient condition under which such a combination is more effective than random sampling. Furthermore, we analyze different strategies of combining random sampling and symbolic execution and

HyChecker has been evaluated with benchmark hybrid systems and a water treatment system in order to test its effectiveness.

Improved Algorithms for Exact and Approximate Boolean Matrix Decomposition [article]

Yuan Sun, Shiwei Ye, Yi Sun, Tsunehiko Kameda
2015 arXiv   pre-print
An arbitrary m× n Boolean matrix M can be decomposed exactly as M =U∘ V, where U (resp. V) is an m× k (resp. k× n) Boolean matrix and ∘ denotes the Boolean matrix multiplication operator. We first prove an exact formula for the Boolean matrix J such that M =M∘ J^T holds, where J is maximal in the sense that if any 0 element in J is changed to a 1 then this equality no longer holds. Since minimizing k is NP-hard, we propose two heuristic algorithms for finding suboptimal but good decomposition.
more » ... e measure the performance (in minimizing k) of our algorithms on several real datasets in comparison with other representative heuristic algorithms for Boolean matrix decomposition (BMD). The results on some popular benchmark datasets demonstrate that one of our proposed algorithms performs as well or better on most of them. Our algorithms have a number of other advantages: They are based on exact mathematical formula, which can be interpreted intuitively. They can be used for approximation as well with competitive "coverage." Last but not least, they also run very fast. Due to interpretability issues in data mining, we impose the condition, called the "column use condition," that the columns of the factor matrix U must form a subset of the columns of M.

Opportunistic Treating Interference as Noise [article]

Xinping Yi, Hua Sun
2018 arXiv   pre-print
We consider a K-user interference network with M states, where each transmitter has M messages and over State m, Receiver k wishes to decode the first π_k(m) ∈{1,2,...,M} messages from its desired transmitter. This problem of channel with states models opportunistic communications, where more messages are sent for better channel states. The first message from each transmitter has the highest priority as it is required to be decoded regardless of the state of the receiver; the second message is
more » ... pportunistically decoded if the state allows a receiver to decode 2 messages; and the M-th message has the lowest priority as it is decoded if and only if the receiver wishes to decode all M messages. For this interference network with states, we show that if any possible combination of the channel states satisfies a condition under which power control and treating interference as noise (TIN) are sufficient to achieve the entire generalized degrees of freedom (GDoF) region of this channel state by itself, then a simple layered superposition encoding scheme with power control and a successive decoding scheme with TIN achieves the entire GDoF region of the network with M states for all KM messages.

Gluons in the Charmonium(-like) States [article]

Wei Sun, Ying Chen, Peng Sun, Yi-Bo Yang
2020 arXiv   pre-print
The mass components of charmonium(-like) states are investigated through the decomposition of QCD energy-momentum tensor (EMT) on lattice. The quark mass contribution ⟨ H_m⟩ and the momentum fraction ⟨ x⟩ of valence charm quark and antiquark are calculated for conventional 1S,1P,1D charmonia and the exotic 1^-+ charmonium-like state, based on the N_f=2+1 gauge configurations generated by the RBC/UKQCD collaboration. It is found that ⟨ H_m⟩ is around 2.0 to 2.2 GeV for these states, which

The ⟨ x⟩ of the 1^-+ state is only around 0.55, while that in conventional charmonia is around 0.7 to 0.8. This difference manifests that the proportion of light quarks and gluons in the 1^-+ charmonium-like state is significantly larger than conventional states.

Nitrogen-Doped Hierarchical Porous Activated Carbon Derived from Paddy for High-Performance Supercapacitors

Yudan Yuan, Yi Sun, Zhichen Feng, Xingjian Li, Ruowei Yi, Wei Sun, Cezhou Zhao, Li Yang
2021 Materials  
A facile and environmentally friendly fabrication is proposed to prepare nitrogen-doped hierarchical porous activated carbon via normal-pressure popping, one-pot activation and nitrogen-doping process. The method adopts paddy as carbon precursor, KHCO3 and dicyandiamide as the safe activating agent and nitrogen dopant. The as-prepared activated carbon presents a large specific surface area of 3025 m2·g−1 resulting from the synergistic effect of KHCO3 and dicyandiamide. As an electrode material,

Furthermore, the assembled symmetric supercapacitor presents a large specific capacitance of 314.6 F·g−1 and a high energy density of 15.7 Wh·Kg−1 at 1 A·g−1, maintaining 14.4 Wh·Kg−1 even at 20 A·g−1 with the energy density retention of 91.7%. This research demonstrates that nitrogen-doped hierarchical porous activated carbon derived from paddy has a significant potential for developing a high-performance renewable supercapacitor and provides a new route for economical and large-scale production in supercapacitor application.

Deciphering the developmental patterns of white matter tracts in a diffusion MRI based fetal brain atlas [article]

Ruike Chen, Cong Sun, Tingting Liu, Yuhao Liao, Junyan Wang, Yi Sun, Yi Zhang, Guangbin Wang, Dan Wu
2022 bioRxiv   pre-print
White matter of the fetal brain undergoes rapid development to form the early structural connections. Diffusion MRI has shown to be a useful tool to depict the fetal brain white matter in utero, and many studies have observed increasing fractional anisotropy and decreasing mean diffusivity in the fetal brain during the second-to-third trimester, whereas others reported non-monotonic changes. Unbiased diffusion MRI atlases of the fetal brain are important for characterizing developmental

To date, the sole fetal brain diffusion MRI atlas was collected from a Caucasian/mixed population, and was constructed based on the diffusion tensor model with limited spatial resolution. In this work, we proposed a fiber orientation distribution (FOD) based pipeline for the generation of fetal brain diffusion MRI atlases, which showed better registration accuracy than diffusion tensor-based pipeline. Based on the FOD pipeline, we constructed the first Chinese fetal brain diffusion MRI atlas using 89 normal fetal diffusion MRI scans at GA between 24 and 38 weeks. Complex non-monotonic trends of tensor- and FOD-derived microstructural parameters in eight white matter tracts were observed, which jointly pointed to different phases of microstructural development. Specifically, we speculated that the turning point of the diffusivity trajectory may correspond to the starting point of pre-myelination, based on which, the developmental order of white matter tracts can be mapped and the order was in agreement with order of myelination from histological studies. The normative atlas also provided a reference for detection of abnormal white matter development, such as that in congenital heart disease. Therefore, the high-order fetal brain diffusion MRI atlas established in this study depicted the spatiotemporal pattern of early white matter development, and findings may help decipher the distinct microstructural events in utero.
