DENG803 - Big Data Analysis and Pattern Recognition Assignment

Assignment Task

Learning Outcomes

1. Evaluate the challenges within big data analytics (data complexity; computational complexity; and system complexity).

2. Hypothesize the development and techniques for the design of systems capable of performing a given recognition task for a specific research application.

Task:

You are required to carry out a simulation and write a report to evaluate the challenges in big data analytic. You are expected to generate synthetic data. Suppose that each object is represented by a 100-dimension data point. The objective is to implement a KNN algorithm where we want to return the K nearest neighbours to a query. You can apply the Euclidean distance between two vectors to calculate similarity. You have to push the limits of the computer you are using by generating a sufficiently large dataset. Then compare the use of a MapReduce framework to a classic implementation. You can use R or any other software to do the comparison. Discuss the data complexity, computational complexity, and system complexity in this context. Discuss the use of such KNN technique in a real-world situation. Where can it be used in a Big Data context?

This IT and Computer Science has been solved by our PhD Experts at My Uni Paper. Our Assignment Writing Experts are efficient in providing a fresh solution to this question. We are serving more than 10000+ Students in Australia, the UK, and the US by helping them to score HD in their academics. Our Experts are well-trained to follow all marking rubrics and referencing styles.

Be it a used or new solution, the quality of the work submitted by our assignment experts remains unhampered. You may continue to expect the same or even better quality with the used and new assignment solution files respectively. There’s one thing to be noticed you could choose one between the two and acquire an HD either way. You could choose a new assignment solution file to get yourself an exclusive, plagiarism (with free Turnitin file), expert quality assignment or order an old solution file that was considered worthy of the highest distinction.
