Both stripes and pairs need to be generalized to b. d.For b, you can assume that the count of pairs are already computed in step and you need to reuse their results (read from the result file produced by step a). The sample datasets can be found at: http://fimi.ua.ac.be/data/2. Revising your algorithms (in 1) to count the co-occurrences of pairs of words Count(A,B) and the conditional probability Prob(B|A)=Count(A,B)/Count(A).Your inputs are text files and considering using the following criteria for a unit (corresponding a transaction in 1):a. each line is a unitb. each sentence is a unitc. each paragraph is a unit (Bonus) Run your algorithms on the Enrone email datasets:http://www.cs.cmu.edu/~enron/enron_mail_20110402.tgzSubmission: The source code of six algorithms (stripes and pairs for problem 1 (a& b) and problem2); a simple description on how to run your programs; and a screen shot on running each algorithm. Finally, all your programs shall be tested and run on Amazon EC2, and you need run your program on 4 mappers and 2 reducers. 3.This problem follows the first question. Your input datasets are transactional data with the following format:25 52 164 240 274 368 401 448 538 561 630 687 730 775 825 83439 52 124 205 401 581 704 814 825 83435 249 674 712 733 759 854 95039 422 449 704 825 857 895 937 954 96415 229 262 283 294 352 381 708 738 766 853 883 966 97826 104 143 320 569 620 7987 185 214 350 529 658 682 782 809 849 883 947 970 979227 39071 192 208 272 279 280 300 333 496 529 530 597 618 674 675 720 855 914 932Each line records a transaction (a set of items being purchased together), and can be annotated by its line number, such as T1, T2, T3, …. Your goal is to discover all the transaction pairs (Ti, Tj) whose common items are more than 2 (using Hadoop/MapReduce). For example, T1 and T2 is a good pair as their common items are 3. Note that the number of transactions can be very large (>=1M). Submission: The source code of the algorithm; a simple description on how to run your programs; and a screen shot on running each algorithm. Finally, your program shall be tested and run on Amazon EC2. Hit: Please refer to this paper: http://www.csee.ogi.edu/~zak/cs506-pslc/docsim.pdf

  • $155 USD Jul 9, 2013

    I am reposting this project since the last coder used could not accurately complete the project per our instructions. The previous coder started some of the work, however additional work is needed to complete the project. The coder who is awarded this project can decide to work with the previous coders work already done or create their own new design if desired.We are using the popular Ultimo theme in Magento and need a responsive bulk quantity price grid designed and programmed within this custom Ultimo theme. Each product will have different bulk quantities, prices, and labels so all data is unique to each product and therefore must be individually editable. Some products will only have 1 row of pricing, while others may have 3 rows of pricing. Some products will only have 2 quantity columns. Some products will have different labels and text. I also need the main Magento price removed or hidden since we are only going to use this grid pricing on the site. We must also be able to update all of these fields in the price grid shown with the bulk csv import feature in Magento. We have hundreds of products and need to update using the import feature instead of manually changing these details.We plan on using a Magento extension that hides prices for non-registered users such as http://www.magentocommerce.com/magento-connect/hide-product-price-for-non-registered-users.html . This price grid must also be programmed to work with this extension so we can hide this pricing grid to non-registered users.Any programming done must not modify the core Magento files or any core Ultimo theme files. We don’t want problems when updating both Magento or the Ultimo theme in the future.We would also like to know if a simple editor can be created to globally modify/change the price grid size, colors, shading, font, and font size. Please be aware that this grid must be "responsive" and adjust to different screen sizes and resolutions such as smartphones and tablets like the Ultimo theme currently does.I have uploaded a screenshot showing the details and explanation on this custom grid/table needed. Please review the details before bidding. If you have a better way of setting this up (such as a separate custom attribute), then please let me know.Again, here is a summary of details needed in this project:1. All fields shown must be individually editable within the standard Magento product price admin area. The last coder used could not accomplish this and we could not edit each field individually and we could not add additional pricing rows or edit the labels.2. Price grid must be responsive and the format must properly adjust to fit various screens such as smartphones and tablets as well as normal computer screens. The last coder used had formatting issues on all devices including regular computer screens. The attached doc will show these formatting issues that need to be corrected.3. We may use an extension to hide prices to users that are not logged-in. The pricing grid therefore needs to work with such an extension.4. We must be able to update all pricinig, quantities, and labels by using the built-in Magento bulk csv upload feature. We have hundreds of products with different pricing, quantity and label variables and must be able to update them in bulk instead of manually.5. On product search pages, related items pages, or upsell item pages, the "as low as" price must show the lowest price within the price grid for each individual product.We will also need other Magento work done to this site, so if you do good work on this project then we can hire you for additional work.This project needs to be completed in 10 days or less. Again please review the attached file. Thanks.
