Twitter sentiment analysis of Automotive Brands

How is twitter sentiment data of automotive companies like Tesla, Mercedes, Porsche, Ford and Toyota related to their stock returns?

In this proof-of-concept consulting project for ApiThinking, I constructed the framework required to build the sentiment analysis models, the twitter data collector server aswell as the machinery required to carry out the Bayesian analysis of data to investigate possible correlations with uncertainty bounds.

Time series with neural networks

Can a neural network be used to forecast time series?

In this project I constructed and optimized various single layer neural networks to forecast time series data and compared against ARIMA benchmarks. This was my capstone project for the Udacity Machine Learning Engineer nanodegree and was one of five selected out of a cohort of >400 peers for peer presentation.

Image Classification with Deep Neural Networks

How difficult is it to implement and train a convolutional neural network image classifier?

In this project I implemented three different, basic, convolutional neural network architectures inspired by the most state of the art models for the purpose of classifying images into four categories using the Pascal VOC 2007 data set. The training of the entrire network was done from scratch and carried out in a Kaggle Kernel. This was my final project from the 5th European data science summer school.
