Project 4: It's Just a Jump to the Left and a Step to the Right
In this project, you will implement a basic unbalanced binary search tree and then add balance features to obtain optimal height.
Part I – Unbalanced Tree
Your primary focus in this part is recursion. Conceptually, binary search trees are fairly simple structures, so let’s take advantage of this implementation to develop our recursion skills. Review the recursive algorithm description in the BST…

Project 3: Queue the Stacking of the Deque
In lecture, we have seen that a deque can serve both as a stack and as a queue depending on usage. We have also seen that a deque can be implemented using a linked list or an array to store its data. We will employ both of those features in this project.
Because we will use a deque as the storage medium for our queues and stacks, we will begin there. You will implement two deque classes, one…

Assignment Goals
Get Pytorch set up for your environment.
Familiarize yourself with the tools.
Implementing and training a basic neural network using Pytorch.
Happy deep learning 🙂
Summary
Home-brewing every machine learning solution is not only time-consuming but potentially error-prone. One of the reasons we’re using Python in this course is because it has some very…

Clustering Homework 4 Solved
Process the real-world data
Implement hierarchical clustering
Visualize the clustering process
You are to perform hierarchical clustering on publicly available Pokemon stats. Each Poke-mon is defined by a row in the data set. Because there are various ways to characterize how strong a Pokemon is, we summarize the stats into a shorter feature vector. For this assignment, you must…

Object Oriented Programming Solution
This assignment will focus on the concepts of Object-oriented programming in C++. In this assign-ment, you will create 5 classes with member variables and functions, using inheritance. You will also demonstrate multiple inheritance and write a program that creates a vector of type base pointer, which can hold the object to any derived class instance. Using polymorphism, the display functions will…

Basics of C++ – MathLib Solved
This assignment will focus on the basic operations of C++. You will create a math library from basic principles using the basic C++ operators (+,-,/,%,type casting, etc). That means you should not use any pre-built functions or libraries except where it is explicitly allowed. You can, of course, use the functions in your library in the other functions of the library.
The library will be a c-style…
