Analysis of Million Songs Dataset using Hadoop MapReduce

This project was an introduction to using Hadoop MapReduce to analyze a large file (~1.6 GB), namely the Million Song subset containing 10,000 songs. The files were stored using HDFS and cluster size consisted of 10 machines. There are 10 Java files with jobs of their own which are focused on answering the 10 questions below. Please visit the github for more details on the questions, answers, and more.

Fast Multithreaded Matrix Multiplication

This is a very efficient matrix multiplication calculator built using Java and its concurrency libraries. It can be used to multiply matrices populated using a random seed, but it can also be modified to use predefined values. The command line gives you the option to define the size of the matrices, which will be the same for both matrices, the seed used in random to populate the matrices, and the number of threads. The features list below describes the optimizations.

This is a feature mainly used to demonstrate the use of the handwriting app built using a canvas and CNN. You can use the search bar to search the site for content or to navigate the site by typing in a word such as home, which will take you to the home page. Below the search bar is a canvas where you can draw letters. This is implemented using a digit recognition CNN. As the accuracy is around 89 percent, it might not always produce an accuracte prediction, for example between o and 0. You can use the three button next to the search bar to delete the last character, clear the search bar, and finally search the site.
