In this project I did some analysis with local MySQL database, I used some queries to check the data errors and inconsistencies, loaded the data into Tableau and did some cleaning to prepare the data for analysis and building the dashboard in the picture.

In this project I used some python libraries to build an app that grabs real stock data and predict closing price, the user can train the model themselves on the interval of data that they wish

In this task, I built a Pytorch dataset class and logistic regression model with Pytorch to train on any football dataset, The model uses one layer and one sigmoid unit as output which is a logistic regression essentially (the client wanted logistic regression), However I decided to use Pytorch to make the model easy to upgrade to a deeper neural network. The dataset class generates for each match a vector of previous matches results for home and away team so that the model can use the teams history in predictions. I included some code snippets shots of dataset definition and model training.

In this project, a public dataset by IBM was used to analyse employee attrition. The main task was to analyse why employees may leave a company at some point. First, I performed an extensive analysis of several factors like job role, salary, distance from home etc. and how each one of them impact the probability that the employee might leave. Second, I picked the most indicative features and built a classification model (deep neural network) with keras and tensorflow and achieved an f1 score of 83 and accuracy of 85, then tried several approches to overcome the class imbalance issue and achieved 86 % f1 score. Below are some visuals of feature analysis and deep learning training process and code.

In this project I worked with a dataset of hourly Electric power output of PV systems installed cross Belgium and connected to the nation grid, The objective was to forecast the hourly power yield in MW for the next 24h and one week horizons. I chose normalized root mean squared error as a percentage metric to measure model performance, then I run a Bayesian hyperparameter tuning loop to achieve best performance possible in the shortest amount of time. The pictures illustrate code snippets for feature engineering and metrics measurement, formulas for metrics used, hyperparameter tuning results and finally example of predictions generated by the model.
