Below highlight a collection of projects I've worked on. A few years ago I decided to make Artificial Intelligence my single focus as an engineer, and recently refined my focused on applying AI/ML algorithms and systems to relationships and experiences. A bit of a catch-all for my ventures in this space!

Object Detection from ResNET34 Model

June 6, 2018

Object Detection is still one of the big open problems in the Computer Vision world. Convolutional Neural Networks have made incredible strides towards solving this problem, which have led to robust A.I systems dealing with face detection, people counting, object tracking and image content filtering…

PyTorch vs. Keras: Sentiment Analysis using Embeddings

May 26, 2018

In this writeup I will be comparing the implementation of a sentiment analysis model using two different machine learning frameworks: PyTorch and Keras. I will design and train two models side by side — one written using Keras and one written using PyTorch. Keras is a high level machine learning…

Image Recognition with a Convolutional Neural Network

May 5, 2018

In this write up I will be developing a Convolutional Neural Network to do image recognition. I will be working with the CIFAR-10 dataset. This is a very popular image dataset for developing and testing Machine Learning algorithms. Due to image size and data quality, it is a lot faster and less…

Analysis and Regression model

April 11, 2018

What does an Engineer need to do to deploy a Machine Learning model to a software application? There is a lot that into a full pipeline — from aggregating the data from source, cleaning, pre-processing and transforming to a model-friendly input, training the model to the point of generating accurate…

SQL Development for Financial Variance Reporting

April 8, 2018

This write up walks through the development of a business query that identifies cost variances in invoices and purchase orders. I will be explaining the logic used to develop the sub-queries as well as the final join to produce the query results. When your company creates a purchase order, there may…

MIT Nuts And Bolts: New Ventures

January 15, 2018

This past winter MIT offered an extracurricular course called “Nuts and Bolts of New Ventures”, where lecturers from Sloan School of Management and run the MIT 100k pitch competition bring practical guiding advice on the mechanics of creating a new business or venture. This course is offered once a…

Transfer Learning Feature Generator

November 17, 2017

I was working with a mathematician from Harvard on a novel data processing algorithm, and one of the tasks laid out was to create a benchmark that would measure the effectivness of this new technique against current state-of-the-art machine learning models. The proposal of this new algorithm was…
