Hidden Markov Models: Extensions
A overview of extensions of HMMs, including the forward backward algorithm and the Baum-Welch algorithm.
Get to know me
I am just your ordinary, everyday nerd who is passionate about statistics, problem solving, and programming. I am always trying to learn new things and expand my knowledge and abilities. I work to best contextualize problems , build innovative solutions and optimize these solutions to better the world around me. I love the challenge of deciphering the unknown using data, statistics, and automation, and have dedicated my livelihood to using these tools to understand as much of this world as I can manage.

Things I Love
It started in college on a cold September day in Probability Theory when I first realized the beauty and power of statistics, and I have never looked back!
Knowing just the theory isn't quite enough. Knowing how to ask the right questions is far more important -- after all, the perfect solution to the wrong question is useless.
When I first helped a collegue to learn how to use dictionary comprehensions in python, it occured to me that I gain a great deal more satisfaction in helping others learn than when I learn myself!
I am passionate about coding best practices , documentation and testing , as well as practical efficiency. May sound strange to be passionate about these things, but here I stand. In the digital flesh.
I'll attack the elephant in the room: why does a Data Scientist have a website like this? Good question. After working a bit with plotly and d3.js , I started becoming interested in HTML, CSS and Javascript. This helps my visualizations out. A lot.
If you can't tell yet, I have a lot of interests, from Data Science to Software Engineering, Web Development to Music/Writing. The one constant in all of this: I love to learn, to improve, and to create new things, be it a model, a website, or a paper.
Other Things I Like
I am a musician, and often play many instruments such as piano, guitar and my electronic drum kit. I have composed orchestral music and enjoy nerding out over music theory.
I have written many short stories, poems, and other creative writing works. To see more of my music and/or writing, feel free to visit my creative website, ammiraticreations.com
I have built my own home server, and love self-hosting services. I love computers, and own a Mac, Linux and Windows at home.

Accelerated B.A./M.A. Program (both Bachelor's and Master's in five years)
My self-perceived level of knowledge in some areas (The cooking is for a reference class...)
The video is the result of one of my projects, the deep lyric visualizer.
The project uses a GAN (Generative Adverserial Network) to generate images based on the tempo, pitch, and lyrics of the song that is playing.
