Referencing the Learning Resources for this module, choose a different question from the previous discussion in the research project list and answer it in relation to an issue in art and technology.What is the problem for which this technology is the solution?Whose problem is it?Which people and what institutions might be most seriously harmed by a technological solution?What new problems might be created because we have solved this problem?What sort of people and institutions might acquire special economic and political power because of technological change?What changes in language are being enforced by new technologies, and what is being gained and lost by such changes?

Design Two Differents Web Pages For A News Company. One Page Is Targeted For Their Younger Millennial/Gen Z Audience. The Other Is Targeted For Seniors 65+. Explain You Different Design Decisions For These Different User Groups

There is a relationship between policy evaluation and production identification, policy evaluation and policy implement, and policy evaluation and policy formulation. Can you explain this relationship and why they are important?

ConstraintHandlingPoints 100, Due: April 11Note: Different tasks for the undergraduate and graduate sectionsIn this project you will implement a binary-coded (bit-string) GA to solve the 0-1 knapsackproblem of size 20. Create (possibly randomly, within some bounds) your own weights wi’s,values vi’s and knapsack capacity W (being able to create meaningful problem instances is animportant learning activity), where i runs from 1 to 20. (Study the discussion in Section 4.5 ofMichalewicz on the difficulty levels of different types of knapsack problems.) Implementproportional, stochastic binary tournament, and linear ranking selection in the same program(allow the user to choose one of these three).• The undergrad section will implement one of the static penalty approaches.• The grad section will do both: (one) static and (one) dynamic penalty methods.Explain in the report the penalty methods you used. Include in your results two extreme cases(the one where no single item can be fit in the knapsack and the one where the problem istrivially solved, i.e., the knapsack can hold all the items), in addition to one “regular” case. [Thismeans a total of three problem instances will need to be created and solved.]The output should include the problem statement (weights, values, capacity of the probleminstance) and averages over 10 independent runs of the best-of-run solutions on each of thethree instances. Submission and group instructions are as before.

Discuss insertion, deletion, and modification anomalies. Why are they considered bad? Illustrate with examples.

CSE 5160 Machine Learning (Spring 2021) Assignment #3 (Due on April 16th, 2021)All assignments are to be submitted to Blackboard. Please note that the due time of each assignment is at 11:55 pm (Blackboard time) on the due date. Please make sure to “submit” after uploading your files. Please do not attach unrelated files. You will not be able to change your files after deadline. 1. [40 marks] (Logistic Regression) Logistic regression aims to learn the parameters ??? from thetraining set ?? = {(???(“),??(“)), ?? = 1,2, . . . ,??} so that the hypothesis ?$(???) = ??(??%???) (here??(??) is the logistic or sigmod function ??(??) = & &’ )!”) can predict the output ?? ? {0,1} givenan input vector ???. Please derive the stochastic gradient ascent rule for logistic regressionlearning problems.2. [40 marks] (Logistic Regression) Manually train a hypothesis function based on the followingtraining instances using stochastic gradient ascent rule. The initial values of parameters are??* = 0.01 ,??& = 0.01 ,??+ = 0.01. The learning rate ?? is 0.5. Please update each parameter aleast five times.??& ??+ ??0 0 0 0 1 0 1 0 1 1 1 1

Mathematical and Computational Modeling in Systems EngineeringCoursework 10Your model has three input variables that you use: (A, B, and C). Currently you use (0.5, 6, 3). You believe that actual values of these input variables follow a uniform distribution. The bounds for A are 0 and 1; B are 3 and 9; and C are 0 and 10.You intend to do ten runs for your sensitivity analysis. Create a Latin Hypercube sampling scheme for this sensitivity analysis. CLEARLY Describe the steps you choose and provide an example input scheme.I suggest that do this in Microsoft Excel. You will need to use the RAND function. You might also require the “paste special” function.

Data Modelling and Database DesignAssessment 2 Data Implementation – Case Study The following case study models a mobile phone company. The company has a number of phones that are sold by staff to various clients. Each phone comes with a plan and each plan has a number of features specific to that plan including:• a call charge in cents per minute (this does not apply to all plans) • a plan duration in months • a break fee if the customer leaves the plan before the end of the plan duration • a monthly data allowance in gigabytesAssumptions that are made for the assignment are:• mobile phones are locked to a plan for the length of the plan duration Entity-Relationship DiagramRelational ModelCUSTOMER CALLS MOBILE STAFF TOWER CONNECT PLAN CustomerID CallsID MobileID StaffID TowerID ConnectID PlanName Surname MobileID PhoneNumber Surname Location TowerID BreakFee Given CalledNumber BrandName Given Bandwidth CallsID DataAllowance DOB CallDate Joined DOB MaxConn MonthlyFee Sex CallTime Cancelled Sex SignalType PlanDuration PhoneHome CallDuration PlanName Joined CallCharge PhoneWork DataUsage PhoneColour Resigned PhoneFax CustomerID Address Address StaffID Suburb Suburb Postcode State Phone Postcode SupervisorID Commission RatePerHour

Instructions:Create a Powerpoint slide deck which includes a 8-10 minute presentation based on what you have learned in this course. The goal here is to quickly and succinctly cover the major areas of the course. You should NOT attempt to cover every detail.Assignment:You are to create a presentation regarding information /knowledge gained on topics found in Chapters 3, 5, 9, 10, 13, and 15.At least 8 slides are required. A title page and reference page is also needed and not included in the 8 slides. Speaker notes are also required.You are to explain Database Administration to someone who wants to be a Database Administrator.

Discussion:Consider the mean of a cluster of objects from a binary transaction data set.1. What are the minimum and maximum values of the components of the mean?2. What is the interpretation of components of the cluster mean?3. Which components most accurately characterize the objects in the cluster?Please clearly LIST your response out to all THREE (3) questions and ensure to cite the specific article with the binary transaction of data set. I will be examing this for myself and other students should verify this as well. Provide the Author, YYYY and specific page number, with any content brought into the discussion.Assignment:Answer the following questions in a point by point fashion. NOT an essay. Please ensure to use the Author, YYYY APA citations with any content brought into the assignment.For sparse data, discuss why considering only the presence of non-zero values might give a more accurate view of the objects than considering the actual magnitudes of values. When would such an approach not be desirable?Describe the change in the time complexity of K-means as the number of clusters to be found increases.Discuss the advantages and disadvantages of treating clustering as an optimization problem. Among other factors, consider efficiency, non-determinism, and whether an optimization-based approach captures all types of clusterings that are of interest.What is the time and space complexity of fuzzy c-means? Of SOM? How do these complexities compare to those of K-means?Explain the difference between likelihood and probability.Give an example of a set of clusters in which merging based on the closeness of clusters leads to a more natural set of clusters than merging based on the strength of connection (interconnectedness) of clusters.
