Nowadays, these big data have been usedfor data mining, knowledge discovery, machine learning, statistical learning, statistical analysis andexperiments. In order to extract or discover useful data, information or knowledge from these big data, one ofmethods we Usually adopt is the sample selections.In this mini-project, you are expected to extract a subset of samples from these big data. In order to extract thissubset of data (samples), we have to make sure that the subset extracted or selected should be as fair andunbiased as possible and as optimal as possible. In the following we propose one method.Assume there are m samples (45m54), any n (7n25) samples out of these m samples are selected. Thereare mCn groups of n samples. From one of these groups of n samples, we randomly selected e.g., k=6 (4k7)samples to form some groups. So there will be nCk groups of k=6 samples selected. Among these groups of k=6samples, we would like to optimize them by selecting ONLY some of them. The conditions that need to befulfilled are listed as follows:1. There are at least ONE group of k samples, in which s (3s7) samples have been selected from the j(where sjk) samples, i.e., when j=4, we have s=3 or 4; when j=5, we have s=3, 4 or 5; when j=6, wehave s=3, 4, 5 or 6; and when j=7, we have s=3, 4, 5, 6 or 7.E.g. 1, when m=45, n=7 (assume we have chosen 7 samples, A,B,C,D,E,F,G and k=6, j=5, s=5, we couldobtain the following minimum 6 groups of k=6 samples, which guarantee at least ONE group of k=6samples has s=5 samples groups from ALL j=5 samples groups of n=7 samples, (i.e., 7C5 and 5C5).1.

A system title is given, e.g, An Optimal Sample Selection System.3. The user needs to input the values for parameters m, n, k, j and s.4. The system can randomly select n numbers out of m numbers and display these numbers of n number.5. Output groups of k samples (results) to a DB file, e.g., 45-9-6-4-4-x for m=45, n=9, k=6, j=s=4 for the xthrun.6. Provide a mechanism to DISPLAY and DELETE the obtained groups of k samples (results) onto the screen from aDB file, e.g., 45-9-6-4-4-x.These groups of k samples are selected from the list.7. Students are required to form groups yourselves. Each group should have 3 students. You are advised to include inyour group at least ONE student who knows how to do programming in MS ACCESS 20XX and VBA, C, C++, Java,MATLAB, etc.8.

Group numbers will be provided later for each group.10. A presentation and demonstration is a MUST in week 15.11. Each group is required to have a 10-15 minutes presentation which includes the introduction, description of method(s)adopted, what have been achieved in this project, and a demonstration of your system is a MUST in this presentation.12. A clear, succinct, easy to understand detailed REPORT of user manual/guide on how to INSTALL and EXECUTEyour DEVELOPED system. The REPORT must include method(s)/methodology (supported by diagram(s), etc.),features you have developed/used, contributions such as good running time, optimal/near optimal results, etc.,and problems such as long time to get results, results not good enough, etc. of your system, results of sampleruns, etc. should be submitted in hardcopy.13. You are required to submit a USB which contains your developed system, all your source files (codes), free/sharewares, database files, DB files of k samples (sample runs outputs/results), and the REPORT mentioned in point 12.14. Bonuses will be given to group(s) that allow users to select as many different parameters as possible for m, n, k, j ands, good method(s) Adopted, could generate optimal/ near optimal solutions. Furthermore, bonuses will be given to thedeveloped system(s) that could be executed in a short time, i.e., having good time complexity.15. The deadline is Week 15 in the presentation sessions. All teams must submit their projects in a USB and hardcopy ofthe REPORT in Week 15. Group number, names, student numbers of your group members should be listed in yourREPORT.如有需要，请加QQ：99515681 或邮箱：99515681@qq.com
