Courses

The course studied both supervised and unsupervised learning. Furthermore, the course covered fundamental machine learning concepts from a theoretical and practical perspective.

Topics studied:

• Regression
• KNN Classifiers
• Neural Networks & perceptrons
• SVMs
• Bagging & Boosting
• Regularization techniques & hyperparameter tuning
• clustering
• Principle component analysis (PCA)
• Markov decision processes (MDP)

The course heavily relied upon fluency with Pandas and Numpy, and coding problems were routinely assigned.

See my hyperparameter tuning on the adult dataset. See my K-Means++ algorithm on the IRIS dataset.

Studied UNIX-style operating systems and its architecture, relying on the C language.

Topics studied:

• Dynamic memory allocation
• Virtual memory & Caching
• CPU Scheduling & algorithms
• Parallel processing
• Semaphores & condition variables

The course consisted of multiple programming projects, the two most noteworthy being a dynamic memory allocator using segregated free lists and a multithreaded channel buffer system.

See my dynamic memory allocator. See my buffered channel interface.

This course studied algorithmic design and how to solve problems with algorithms.

Topics studied:

• Asymptotic runtime & spacetime analysis
• Divide-and-conquer & comparison based algorithms
• Recursive algorithms
• Greedy algorithms
• Graph algorithms
• Dynamic programming & memoization

The use of correctness proofs and space/time complexity analysis when studying algorithms was strongly emphasized.

Technologies explored include the C programming language (useful functions/system calls, data types, libraries), UNIX OS, and Git.

An understanding of UNIX and its tools/environment was necessary (Ubuntu VM was used for all coursework).

Topics studied:

• UNIX Shell and shell scripting
• GCC compiler
• Makefiles & build sequences
• Memory management
• Caching
• File systems
• Signal processing
• Socket programming
• Parallel programming

The final project was a JBOD driver interface, implementing command processing, read/write calls, and caching. Remote read/write calls for JBOD servers were also implemented using sockets.

See my JBOD driver interface with C.

CMPSC221 taught the basics of GUI programming with an object-oriented approach. The class also covered the material involving relational databases. The main language used was Java, but learning SQL was another requirement.

Noteworthy projects include a drawing application made with JFrames and a room reservation software using Java and Apache Derby.
