Assignment 2: Data manipulation Submit a document where you answer the following questions along with the R script you used. This does not have to be a managerial report. Import your data into R-Studio. Filter the data to include only residential real estate of your neighborhood. Group it by year, and summarize the data to show the average price of 1 square foot of real estate. List the results. Do numbers show for all years? If a year shows N/A, why is that happening? Filter your data to focus on residential real estate with adequate information for your model (remove fields with 0 for price or square feet) Group the filtered data by year, and summarize the data to show the average price of 1 square foot of real estate. List the results. Compare your selected neighborhood with 2 nearby neighborhoods. List the numbers. Produce a plot that compares the neighborhoods. Explain the plot and the reason you chose that type of plot. https://www.sendspace.com/file/qnlrh9Here is the link Please select just one of the bullet points listed below. The different sources mined for descriptive analytics data and their respective benefits. Discuss the descriptive statistical measure of your your choice, and its significance in descriptive analytics. (Mention a use case or an Example) When do we need to use standardization? Why? (Use Examples) Choose a topic from lecture 5 other that the above.

Choose one of the following strategies for reducing the costs associated with responding to cyberattacks from the Rand Report* (A Framework for Programming and Budgeting for Cybersecurity): Minimize Exposure Neutralize Attacks Increase Resilience Accelerate RecoveryThen, prepare a two-page briefing paper (5 to 7 paragraphs) for the Red Clay senior leadership and Red Clay corporate board that addresses planning, programming, and budgeting processes for your strategy. Your audience is the company’s IT Security Working group and includes both technical and non-technical managers and senior staff members responsible for budgeting. The general questions that this audience is interested in are:Planning: What will we do? (your chosen cybersecurity strategy)Programming: How and when will we do it?Budgeting: How much will it cost and how will we pay for it?Remember to keep your focus on the processes related to planning, programming, and budgeting not the actual hardware, software, etc. that needs to be acquired and paid for. You may, however, provide examples of hardware or software.Provide in-text citations and references for 3 or more authoritative sources. Put the reference list at the end of your posting.*Rand Report: Davis, J. S., Libicki, M. C., Johnson, S. E., Kumar, J., Watson, M., & Karode, A. (2016).

Instructions are attached.Kohonen algorithm.(See Text (Faussett) , chapter 4 and p. 183 for examples of snapshots in a different problem.)Prepare a full report on what you did including results, learning rates, number of iterations until convergence .It is important to includescreenshots of the snapshots at different iteration times of the algorithm , Implement the Kohonen algorithm (your own code ) to perform the following tasks.For each of these show "snapshots" of the placement of the neurons at different number of iterations of the algorithm.It may be best to start the initial "locations" of the neurons as small random (x,y) values (i.e. all between -.2 < x,y< .2 Given a sequence of30 neurons arranged in a straight line;take data from a circle of radius 2 (centered at the origin), with the data points chosen uniformly and randomly within the circle.Do the same when the 30 neurons have the topology of a circle.Do the same for 25 neurons arranged in a 5 x 5 topology.Now repeat A, B, and C above but where the data is chosen randomly but with a probability proportional to the distance from the center.Now repeat A and Bbut where there are two concentric circlescentered at the originone with radious 2 and one with radius 4;andall data is chosen from the ring between radius 2 and radius 4.
