Luis G. Chinchilla-Garcia
I am a Data Scientist and Machine Learning Engineer who also delves into the worlds of Data Engineering and Web Development. Currently, I am a Lead Data Scientist at NBC Universal, where I focus on creating scalable end-to-end machine learning models for Recommender Systems.
I graduated from the University of California, Los Angeles with a BS in Astrophysics. During that time, I completed four years of research as part of a research fellowship and was also a co author in a paper (details below).
Skills and Experience
For Machine Learning Engineering, some of my responsibilities have included:
- Actively researching and prototyping machine learning models to personalize product recommendations utilizing frameworks like Tensorflow and PyTorch
- Deploying machine learning models on cloud services as part of an end-to-end machine learning workflow
- Developing & maintaining end-to-end machine learning pipelines that are scalable and cost effective
- Utilizing frameworks like Tensorflow Extended with AI Platform to develop, test, and deploy machine learning models
Projects
Below are some of the most recent projects I have been working on
Probabilistic PCA
- Extending Principal Component Analysis(PCA) to use a probabilistic approach.
- In doing so, it is possible to push the use of PCA and generate new outputs.
Extending Probabilistic Linear Regression
- Linear regression is a foundational part of mathematics that provides the foundation to machine learning.
- This project revolves around extending linear regression with probability and its practical uses.
Music Chord Progressions
- Utilizing both Sequence and Attention based models to generate a sequence of chords.
- Data from this project is personally taken using MIDI files or transcriptions of chord progressions in musical pieces.
- This section is focused on crating the model itself using Tensorflow.
