Learning Dual-Layer User Representation for Enhanced Item Recommendation

User representation learning is crucial for capturing different user preferences,but it is also critical challenging because user intentions are latent and dispersed in complex and different patterns of user-generated data,and thus cannot be measured directly.Text-based data models can learn user representations by mining latent semantics,which is beneficial to enhancing the semantic function of user representations.However,these technologies only extract common features in historical records and cannot represent changes in user intentions.However,sequential feature can express the user’s interests and intentions that change time by time.But the sequential recommendation results based on the user representation of the item lack the interpretability of preference factors.To address these issues,we propose in this paper a novel model with Dual-Layer User Representation,named DLUR,where the user’s intention is learned based on two different layer representations.Specifically,the latent semantic layer adds an interactive layer based on Transformer to extract keywords and key sentences in the text and serve as a basis for interpretation.The sequence layer uses the Transformer model to encode the user’s preference intention to clarify changes in the user’s intention.Therefore,this dual-layer user mode is more comprehensive than a single text mode or sequence mode and can effectually improve the performance of recommendations.Our extensive experiments on five benchmark datasets demonstrate DLUR’s performance over state-of-the-art recommendation models.In addition,DLUR’s ability to explain recommendation results is also demonstrated through some specific cases.

The Ordinal Interpretation of the Integers and Its Use in Number Theory

The author recently published a paper which claimed that an ordinal interpretation of numbers had limited applicability for cryptography. A further examination of this subject, in particular to what extent an ordinal interpretation is useful for recurrence sequences, is needed. Hilbert favored an interpretation of the natural numbers that placed their ordinal properties prior to their cardinal properties [1] [2]. The author examines ordinal uses of the integers in number theory in order to discuss the possibilities and limitations of this approach. The author hopes this paper will be useful in clarifying or even correcting some matters that were discussed in his paper of January of 2018. I was trained informally in philosophical realism, and while I think idealism too has a place, at this time in my life I believe that the weight of evidence and usefulness is more on the side of philosophical materialism. I hope this discussion will help supplement for my readers the material in Number in Mathematical Cryptography. I still maintain that a lack of clarity on these matters has hindered progress in cryptography;and it has taken time for me to better understand these things. I hope others who have interest and ability will assist in making these matters clearer. My intention was to work in pure mathematics, and the transition to an applied mindset was difficult for me. As a result, I feel most comfortable in a more middle-of-the road attitude, but have had to slowly move to a more precise analysis of the physical quantities involved. I hope my readers will be patient with my terminology, which is still evolving, and my discussion of things which are more indirectly related, and which are necessary for my expression. These are important things for the mathematical community to understand, and I hope smarter and more knowledgeable people will address my errors, and improve upon the things I might have correct. I am discussing sequences which are sometimes a use of both ordinal and cardinal numbers.

Resolution of Hardy’s Paradox within Spacetime Physics and the Ithaca Interpretation of Quantum Mechanics

By religiously adhering to physics in spacetime and taking the final verdict of N.D. Mermin’s Ithaca interpretation of quantum mechanics seriously, Hardy’s paradox is completely resolved. It is then concluded that logical and mathematically consistent physical theories must be put in spacetime related formalism such as noncommutative geometry and E-infinity theory to avoid quantum paradoxes. At a minimum, we should employ the philosophy behind consistent quantum interpretation such as that of the famous Ithaca interpretation of D. Mermin.

A New Interpretation of Quantum Mechanics

The Copenhagen interpretation is the most authorized interpretation of quantum mechanics, but there are a number of ideas that are associated with the Copenhagen interpretation. It is ceratin that this fact is not necessarily desirable. Thus, we propose a new interpretation of measurement theory, which is the linguistic aspect (or, the mathematical generalization) of quantum mechanics. Although this interpretation is superficially similar to a part of so-called Copenhagen interpretation, we show that it has a merit to be applicable to both quantum and classical systems. For example, we say that Bell’s inequality is broken even in classical systems.

An Ecological Interpretation of Consumer Culture in Willa Cather's The Professor's House

The Professor's House presents the readers pictures with striking consumer culture characteristics. With abundant goods of sign values, conspicuous consumption, swelling-desire-stimulating power and the individuals' efforts to construct their identities through consumption as dominant features, consumer culture exerts negative and even devastating effects on the characters in the novel. Theories of ecocriticism shed new lights on the interpretation of consumerism reflected in the novel, especially on analyzing how the consumer culture makes the characters suffer from split personality, alienation from nature, society, and even from themselves and their spiritual ecology.

Customization Product Design Based on User's Emotion and Needs

The paper presents a design method that ensures the ingenuity of the product form as well as the whole and exact expression of user’s needs. The key idea is to establish an automatic design system which can transform the user’s language needs into the product features in real-time. A rifle was taken as a research instance and soldiers were chosen as evaluation customers. The theory of fuzzy set and semantic difference are adopted to evaluate the relationship between user’s needs and product features as well as their alternatives. FAHP (fuzzy analytic hierarchy process) is utilized to judge the user’s satisfactory forms. This method can also be applied to other product form designs.

Use of methotrexate in inflammatory bowel disease in 2014: A User's Guide

However,many physicians are unfamiliar or uncomfortable with its use in the management of inflammatory bowel disease. We summarize the data for use of methotrexate in common clinical scenarios:(1) steroid dependant Crohn's disease(CD);(2) maintenance of remission in steroid free CD;(3) azathioprine failures in CD;(4) in combination therapy with Anti-TNF agents in CD;(5) decreasing antibody formation to Anti-TNF therapy in CD;(6) management of fistulizing disease in CD; and(7) as well as induction and maintenance of remission in ulcerative colitis. An easy to use algorithm is provided for the busy clinician to access and safely prescribe methotrexate for their inflammatory bowel disease patients.

Frequent Itemset Mining of User’s Multi-Attribute under Local Differential Privacy

Frequent itemset mining is an essential problem in data mining and plays a key role in many data mining applications.However,users’personal privacy will be leaked in the mining process.In recent years,application of local differential privacy protection models to mine frequent itemsets is a relatively reliable and secure protection method.Local differential privacy means that users first perturb the original data and then send these data to the aggregator,preventing the aggregator from revealing the user’s private information.We propose a novel framework that implements frequent itemset mining under local differential privacy and is applicable to user’s multi-attribute.The main technique has bitmap encoding for converting the user’s original data into a binary string.It also includes how to choose the best perturbation algorithm for varying user attributes,and uses the frequent pattern tree(FP-tree)algorithm to mine frequent itemsets.Finally,we incorporate the threshold random response(TRR)algorithm in the framework and compare it with the existing algorithms,and demonstrate that the TRR algorithm has higher accuracy for mining frequent itemsets.

User’s Relevance of PIR System Based on Cloud Models

A new method to evaluate fuzzily user＇s relevance on the basis of cloud models has been proposed. All factors of personalized information retrieval system are taken into account in this method. So using this method for personalized information retrieval （PIR） system can efficiently judge multi-value relevance, such as quite relevant, comparatively relevant, commonly relevant, basically relevant and completely non-relevant, and realize a kind of transform of qualitative concepts and quantity and improve accuracy of relevance judgements in PIR system. Experimental data showed that the method is practical and valid. Evaluation results are more accurate and approach to the fact better.

C -E Interpreting of Political Neologisms in Contemporary Chinese Political Discourse

Uniqueness of our political systems and tremendous changes brought about by reform and opening up are reflected in language use,so contem porary Chinese political discourse has its own distinctiveness,and is especially featured by increasing political neologisms,posing difficulties for interpreters and for China’s international publicity.Quality of political neologisms interpreting has a direct bearing on whether or not success of interpreting the whole discourse can be achieved.The authors believe that interpreting of contemporary Chinese political discourse,also for the purpose of com m unication can gain guidance from Bachman’s CLA Model.So the paper elaborates through exem plification on strategies for interpreting political neologisms in light of Bachm an’s Model,with a view to realizing discourse power of Chinese.

A Dynamic Bandwidth Allocation Solution Based on User Behavior and Software Defined EPS

For telecommunication operators, how to improve the utilization of bandwidth resources is always a problem which worthy of study, nowadays, this issue has become more and more important, since the traffic load bursting in the mobile Internet. So the key to solving this problem is that we need to find a kind of traffic model to predict the traffic load that users need. According to the predicted traffic load to allocate bandwidth to each base station dynamically.But the traffic consumption behavior of a single base station is random, it is difficult to predict[ 1 ]. For this reason, we based on reality that, when the user moves, it may get traffic load from different base stations, therefore, there will have some kind of relationship between those base stations.We use this relationship to establish a kind of Spatial Collaborative Network.consequently, we make use of stability algorithm to divided those base station cluster into different communities, According to the traffic load usage rules which these communities indicated to us, we get a traffic model.At the same time, we studied bow to use this traffic model in the future networks to dynamically allocate bandwidth resources, then we propose a new kind of EPS architecture based on SDN, on this platform, we can deploy our strategy through it＇s programmable interface.Finally, we designed an experiment to test the performance of our dynamic strategy, and the result shows that our method enables bandwidth utilization has been greatly improved.

Testative Discussion on how to be an Eligible Interpreter--Based on the People’s Republic of China of the National People’s Congress and Committee of the People’s Political Consultative Conference from 2012 to 2014

In recent years,with the rapid development of the Chinese economy,the“two sessions”in March of every year which sponsored by the ministry of foreign affairs attract more and more journalists from all over the world.The press conference in the“two sessions”likes an important window to show China’s policies and claims to the world.Meanwhile,the premier who answers questions in the press conference,respectively,shows the world the eloquence and polite manners of China’s premier,such as Premier Wen Jiabao and Premier Li Keqiang.Their astute response,excellent,and emotional expression makes a deep impression on audiences.Moreover,as a bridge between the speaker and the listeners,the interpretation once is incorrect will cause some mistakes even conflicts.Therefore,the interpreter plays a most important role in the press conference.How to improve the interpretation level in the press conference is a significant topic.The thesis mainly introduces the content of press conference interpreting from 2012 to 2014.At present,the practical study of press conference interpretation is far from enough.The last part gives the summary of the study and points out the main findings for the further study.

Ethical Problems in MTI Students’Escort Interpreting from the Perspective of Chesterman’s Models on Translation Ethics

The professionalization of translation has been discussed by many scholars in recent years,which has inspired the intense discussion of translation ethics.Drawing upon Chesterman’s models on translation ethics,this paper intends to examine the ethical problems in MTI students’escort interpreting for Vanuatu Sport Technical Assistance Project for the Pacific Mini Games in 2017 and China-ASEAN International Capacity Cooperation Forum in 2016.The data was collected by the methods of participant observation and informal interviews in the process of the two interpreting projects,especially the six-month assistance project.The ethical problems in the escort interpreting and the reasons that caused the problems were analyzed through case study.It is found that the major ethical problems that occurred are related to the ethics of communication,the norm-based ethics,and the ethics of commitment.These ethical problems were mainly related to the student escort interpreters’language proficiency,professional qualities,and intercultural/interpersonal communication competence.Some solutions are suggested based on Chesterman’s models on translation ethics.It is hoped that the research findings can provide some references to the implementation of the similar interpreting programs in the future,and enhance interpreting teaching and training programs.

Method of Consistency Judgment for App Software’s User Comments

With the popularity of mobile intelligent terminal, user comments of App software is viewed as one of the research interests of social computing. Faced with the massive App software, most users usually view the other users’ comments and marks to selecting the desired App software. Due to the freedom and randomness of the network comments, the inconsistence between the user’s comment and mark makes it difficult to choose App software. This paper presents a method by analyzing the relationships among user’s comment information, the user’s mark and App software information. Firstly, the consistency between user’s comment information and App software information is judged. Then, through analyzing the grammar relationships among the feature-words, adverbs and the feature-sentiment-words in App software’s feature-sentimentword- pairs, the user’s emotional tendency about App software is quantified quantified combining with the dictionary and the network sentiment words. After calculating the user’s comprehensive score of App software, the consistency of App software’s user comment is judged by comparing this score and the user’s mark. Finally, the experimental results show that the method is effective.

滇西南1976年龙陵M_(S)7.3、M_(S)7.4双强震触发滑坡遥感解译及其构造意义

深入研究中国滇西南地区发育的龙陵-澜沧新生地震构造带对于合理划分活动地块边界及未来开展强震危险性评价工作具有重要意义。使用高分辨率卫星影像对已发生的双强震震例开展回溯研究是一种可行的技术手段。文中对震前、震后高分辨率Keyhole卫星影像进行遥感解译,结合野外验证和前人研究结果,获得了1976年M_(S)7.3、M_(S)7.4龙陵双强震触发滑坡较为完整的数据库。结果显示:1)共解译滑坡14448个,总面积为17.2km^(2),70.9%的滑坡分布在花岗岩质的岩体风化层中,单体滑坡面积集中在数百至1000m^(2)区间,多为表层风化层内的浅层滑坡,滑动距离较小;2)同震滑坡密集区与高烈度区不匹配,其空间分布显示破裂区规模约为30km,且均位于活动断裂的一侧,表明其发震构造并非为龙陵-瑞丽断裂或畹町断裂。滇西南地区共轭强震破裂可能局限了单次强震的空间规模,因此在确认未来强震危险区时应重点关注NE向与NW向构造的交会部位。
