  • A Neural Network Model to Identify Relative Movements from Wearable Devices

    IEEE

    In this paper, we propose a simple neural network model to identify and analyze movement based data collected from wearable devices. The base variables used for the analysis include the relative altitude, the accelerometer acceleration, quaternion, the relative motion of gravity, the user acceleration, and the relative gyro rotation in an x, y, and z plane. Based on previous related studies, extensive feature engineering was utilized to generate 171 unique features from those previously…

    In this paper, we propose a simple neural network model to identify and analyze movement based data collected from wearable devices. The base variables used for the analysis include the relative altitude, the accelerometer acceleration, quaternion, the relative motion of gravity, the user acceleration, and the relative gyro rotation in an x, y, and z plane. Based on previous related studies, extensive feature engineering was utilized to generate 171 unique features from those previously mentioned, which showed a dramatic increase in accuracy. The Label Smoothing Cross Entropy feature was also utilized to make a better generalization of the proposed model. We were able to achieve 95% average on our test data sets which out performed a previous similar work by a good margin of 20%.

  • lib2nbdev

    - Present

    nbdev is a fantastic workflow aimed at centralizing documentation, testing, and source code generation all out of one place: Jupyter Notebooks. However, what if you already have an existing project? As it stands the only way to convert your library over is through manual tasks (which can take > 30 hrs!).

    lib2nbdev is the solution!

    Instead, we can perform a one-time conversion on any existing library. During the conversion process the library will help you generate a proper…

  • NLP Analysis of News Corpus Dataset for General News Reliability

    This project originated as a part of University of West Florida's annual competition CodeFest, where teams are given 48 hours to go from idea to finalized product. I chose to create a natural language processing model utilizing the ULMFiT algorithm in discerning how trustworthy a new source can be from a series of factors. This project won first place within the competition.

  • Lockheed Martin AI Drone Innovation Challenge

    -

    In this challenge, the goal was to find the interior flyable region of a given gate in a picture. For this computer vision centered task, I implemented the YoloV3 algorithm to find each corner within the gate and take the midpoint of each to get me a reliable flyable region. This approached allowed myself and my team to achieve 6th place on the final leaderboard for this particular challenge
