模拟国际会议发言稿【篇一:模拟国际会议演讲稿】recsplorer:recommendation algorithms based on precedence mining1. introductionthank you very much, dr. li, for your kind introduction. ladies and gentlemen, good morning! i am honored to have been invited to speak at this conference. before i start my speech, let me ask a question. do you think recomemdations from others are useful for your internet shopping? thank you. it is obvious that recommendations play an important role in our daily consumption decisions.today, my topic is about recommendation algorithms based on precedence mining. i want to share our interesting research result on recommendation algorithms with you. the content of this presentation is divided into 5 parts: in session 1, i will intruduce the tradictional recommendation and our new strategy; in session 2, i will give the formal definition of precedence mining; in session 3, i will talk about the novel recommendation algorithms; experimental result will be showed in session 4; and finally, i will make a conclusion.2. bodysession 1: introductionthe picture on this slide is an instance of recommemdation application on amazon.recommender systems provide advice on products, movies,web pages, and many other topics, and have become popular in many sites, such as amazon. many systems use collaborative filtering methods. the main process of cf is organized as follow: first, identify users similar to target user; second, recommend items based on the similar users. unfortunately, the order of consumed items is neglect. in our paper, we consider a new recommendation strategy based on precedence patterns. these patterns may encompass user preferences, encode some logical order of options and capture how interests evolve.precedence mining model estimate the probability of user future consumption based on past behavior. and theseprobabilities are used to make recommendations. through our experiment, precedence mining can significantly improve recommendation performance. futhermore, it does not suffer from the sparsity of ratings problem and exploit patterns across all users, not just similar users.this slide demonstrates the differences between collaborative filtering and precedence mining. suppose that the scenario is about course selection. each quarter/semester a student chooses a course, and rates it from 1 to 5. figure a) shows five transcripts, a transcript means a list of course. u is our target student who need recommendations. figure b) illustrates howcf work. assume similar users share at least two common courses and have similar rating, then u3 and u4 are similar to u, and their common course h will be a recommendation to u. figure c) presents how precedence mining work. for this example, we consider patterns where one course follows another. suppose patterns occour at least two transcrips are recognized as significant, then (a,d), (e,f) and (g,h) are found out. and d, h, and f are recommendation to u who has taken a, g and e.now i will a probabilistic framework to solve the precedence mining problems. our target user has selected course a , we want to compute the probability course x will follow, i.e.,pr[x|a].﹁howerve, what we really need to calculate is pr[x|ax] rather than pr[x|a]. because in our context,we are deciding if x is a good recommendation for the target user that has taken a. thus we know that our target user’s transcript does not have x before a. for instance, the transcript no. 5 will be omitted. in more common situation, our targetuser has taken a list of courses, t = {a,b,c,…} not﹁just a. thus, what really need is pr[x|tx]. the question is how to figure out this probability. i willanswer it later.session 2: precedence miningwe consider a set d of distinct courses. we use lowercase letters (e.g., a, b, … ) to refer to courses in d. a transcript t is a sequence of courses, e.g., a - b - c - d. then the definition oftop-k recommendation problem is as follows. given a set transcripts over d for n users, the extra transcript t of a targetuser, and a desired number of recommendations k, our goal is to:1. assign a score score(x) (between 0 and 1) to every course x ∈ d that reflects how likely it is the target student will be interested in taking x. if x ∈ t , then score(x) = 0.2. using the score function, select the top k courses to recommend to the target user.to compute scores, we propose to use the following statistics, where x, y ∈ d:f(x): the number of transcripts that contain x.g(x; y): the number of transcripts in which x precedes course y.this slide shows the calculation result of f(x) and g(x,y). for example, from the table, we know that f(a) is 10 and g(a,c) is 3. we propose a precedence mining model to solve the top-k recommendation problem. here are﹁some notation: xy, which we have memtioned in session 1, refers to transcript where x occurswithout a preceding y; x﹁y refers to transcript where x occurs without y following it. we use quantities f(x) and g(x,y) to compte probabilities that encode the precedence information. for instance, from formular 1 to 7. i would not tell the detail of all formulars. we just pay attention to﹁formular 5, note that this quantity above is the same as: pr[x ﹁y |yx] which will be used toas we know, the target user usually has taken a list ofcourses rather than a course, so we need to﹁extent our probability calculation formulars. for example, suppose t={a,b}, pr[xt] theprobability x occurs without either an a or b preceding it; pr[x﹁t] the probability x occurs without either an a or b following it. this probability can be calculated exactly. so how to calculate it?session 3: recommendation algorithmslet’s review session 2. the main goal of the recommendation algorithms is to calculate the score(x), and then select the top k courses based on these scores. traditional recommendation algorithms compute a recommendation score for a course x ind only based on its frequency of occurence. it does not take into account the courses taken by the target user.our recommendation algorithms called singlemc conquer the shortcoming of the traditional ones. it computes the score(x) using the formular 5. the detail is as follows: a student with a transcrip t of taken courses, for the course y ∈ t, if y and x appear together in transcripts satisfies the﹁and ignoring the effect of the other courses in t; finally the maximum of pr[x﹁y |yx] is choosen asthe score(x).here is the calculation formular of score(x) of signlemc. for example, with the higer score, d will be recommended.another new recommendation algorithm named joint probabilities algorithm, jointp for short, is proposed. unlike singlemc, jointp takes into account the complete set of courses in a transcript. in formular 12, we cannot compute its quantity exactly, remember this problem we have mentioned. our solution is to use approximations. this slide is about the first approximating formular. and this the second approximating formular.the system is courserand, and data set for experiment contains 7,500 transcripts.this slide shows the new recommendation algoritms with black color and the traditional ones with blue color.the chart on this slide indicates our new recommendation algorithms beat the traditional ones in precision, because the former ones exploit patterns across all users, while the latter ones just use the similar users.the chart on this slide points out our new recommendation algorithms also beat the traditional ones in coverage for the same reason.session 5: conclusion and summaryin conclusion, we proposed a novel precedence mining model, developed a probabilistic framework for making recommendations and implemented a suite of recommendation algorithms that use the precedence information. experimental result shows that our new algorithms perform better than the traditional ones, and our recommendation system can be easily generalized to otherscenarios, such as purchases of books, dvds and electronic equitment.to sum up, first, i introduced the motivation and the outline of work; second, i gave the definition of precedence mining model; third, i described some new recommendation algorithms using precedence information; forth, i showed our experimental results to compare the new algorithms with traditional ones. finally, i made a conclusion of our work.. that’s all. thank you! are there any questions?【篇二:国际会议作报告英语发言稿】thank you, prof. …. my name is ….. i’m from ….. i am very pleased to be here to join this forum. the topic of my presentation is properties of rapid construction materials for soil pavement of field airfield. as is shown in the picture, the main parts of my research are about soil pavement.my presentation will include these four parts:first, some background information about this research; second, the main work we have done; third, some conclusions we have got and the last: innovation and presentation of our published papers.why i choose this item? i think it can be illustrated from the following four parts. first, the existing quantity of airfields is still not sufficient and the airfields have many shortcomings especially in war time. second, the complementary facilities, such as highway runways are far less than airfields, however, have more weakness. third, a certain amount of field airfield is quite necessary considering some emergencies such as rescue and disaster relief. forth, the field airfield can fill the void of airfield and they can be combined to be airfield network. the meaning and aim of this research contains three parts. fast, convenient and validity, fast means the field airfield must be constructedas fast as possible, convenient means the construction should need the minimum equipment, labor and materials considering the actual construction condition, validity means the constructed airfield is able to support the operation of given aircraft in specifically time.just like many other territories, the situation of the research is that the u.s. army takes advanced line. the u.s. army declaresthat they can reach to anywhere on the earth in 96 hours, the most important method for force projection is though aircraft, thus rapid construction of pavement is the key problem for rapid force transportation.the main work we have done can be summarized as four parts, materials choosing, scheme making, mechanical properties research and water-stable properties research.we choose two kinds of soils, which are got from xi’an,shanxi province and jiuquan, gansu province separately. the sand from ba river was considerate to investigate the influence of sand to the properties of stabilized soil. the chosen three kinds of powders are cement, lime and new-type stabilizer developed by chang’an university. the principles in considering the function of 4 kings of fibers are referring different length, type and mixing them.on account of the time, i will make a brief description aboutthe experiment scheme. in summary, three parts were proposed to distinguish the affecting factors in making experiment scheme. they are powder control, fiber control and other factors. taking powder control for example, the dosage of cement is respectively 6%, 8% and 10% when the soil is stabilized only by cement, while the dosage of cement decrease to 3%, 5% and 7% when the lime is addicted to stabilized soil. the following two factors are stabilizer and sand. six kinds of experiments were performed to investigate the influence of above factors to the mechanical properties of stabilized soil. the aim of compaction test is to find the maximum dry density and optimum moisture content. the aim of compression strength test is to determine the optimum dosage of cement, lime, powder stabilizer and fiber, meanwhile evaluating the performance of stabilized soil. the aim of splitting tension strength test is similar to compression strength test, the left picture is sample stabilized by cement, while the right picture is the sample stabilized by fiber and cement. the direct sheer is another important parameter in geotechnical engineering. it influences the foundation bearing capacity and many other properties especially for soil baseand base course. the left picture shows the course of making sample and the right picture shows the test process.the cbr test and rebound modulus test are referenced from highway test specification to evaluating the comprehensive capacities of each structure level of the pavement. for both the two tests, the left picture shows the course of making sample and the right picture shows the test process. what should be noted is that the number of sample is at least 6, the last result is the average value of these date got from test after eliminating the bad results.four kinds of experiments were performed to investigate the influence of above factors to the water-stable properties of stabilized soil. the scouring test is not the stated experiment in current specification. it is performed by us through looking up large quantity of interrelated literature, and two different ways to carry out. the left picture shows the method of vibration table and the right picture shows the method of fatigue test instrument. penetrant test refers to the experiment in relating concrete specification. the left picture shows the process of saturation, the right picture shows the test process.cantabria test and other tests are all original experiments; they are used in stabilized soil for first time, here i will not develop my narrative.as regards the innovation, i think it throughout the whole research, including materials choosing, scheme making, mechanical and water-stable experiments. i think it can be drawled from the following keywords, such as soil choosing, sand, powders, fibers, and so on. three main parts can be summarized. first, selecting two kinds of soils, three kinds of powders, several combinations; second, several kinds of fibers, different length and admixture; third, comprehensive experiments, test method and test instrument.【篇三:国际学术会议发言稿】1. prologuethank you, mr. chairman, for your gracious introduction. i am honored to have the chance to address you on this special occasion. the topic of my paper is “transaction cost and farmers’choice of agricultural products selling”. the outline of my talk as follows. the first part i want to introduce the background of this research. the second part suggests a simple household choice model .the third part covers the dataused in this research. and then, we introduce the empirical results. finally, a simple conclusion is given.2. introductionwell, let’s move on the first part of this topic .the motivation of this work like this. institutional economics posits that agents making decisions on different types of transactions do so in a costly way .for example , farmers deciding sell a particular crop to whom base their decisions not only on the price they expect to receive in each market choice but also on additional costs related to transacting in these markets.i want to use a picture to illustrate it. for example, given some market channels, farmers’ choices can be regarded as equilibrium between the surplus and the additional costs that related to transacting .especially in developing countries, high-value crop producers fully participate in the market and the transaction cost has been the hard constraint to farmers. furthermore, farmers’ market choices can be taken as a choice dilemma of transaction cost and production surplus. consequently, the scientific question of this research is how transaction cost affects planters’ choices.3. methodologyq?n?market. the third equationi ? q ? implies the amount exchanged in nth time.in stage 3, farmers will decide to sell the products to whom.c hanel j’s market price isbdecided by an exogenesis price and farmers’ negotiating power. pij?p*j?b(qi,zi)besides this, we use a matrix to show the net profit of chanel jx ik ? ik , ? ?? ik ?and then farmers’ choice can be expressed in a typical choi ce modelexp(xij?)pr(ji?j|xik)?1 exp(xij?)? k?1based on the choice model, another important concept is famers’ channel choice .here, we set five types .they rank by the market barriers. accordingly, we set a group discrete number to express them. y: dependent variable y=5,means farmer choosebrokers. y=1, farmers sell products to consumers directly.4. data and estimation procedureshere, we illustrate the data distribution with this map. according to the agricultural regionalization from department of agriculture, the apple specialization areas in china contain two parts: bo sea area and loess plateau. bo sea area in red color, contains hebei, shandong and liaoning 3 provinces. and loess plateau in green color, contains shanxi, henan, shaanxi and gansu 4 provinces. firstly, we use pps method to get the first stage sampling unit 14 counties in 7 provinces. then use random sample method to get village and household. they are our sample distribution.5. empirical results6. conclusions。
