Skills

Technology

I have extensive practice in using the common Python data stack for data analysis, visualization and modelling.

I am equally experienced in the use of torch and tensorflow for developing more complex machine learning models. Recently I have been experimenting with probabilistic modelling via general purpose packages including tensorflow-probability and pymc3, as well as specialized packages such as gpflow for Gaussian processes.

Besides Python, I can also use R for analysis and statistical modelling, and SQL for relational database management.

Lately I have also been focusing on improving my use of Docker and various services offered by AWS.

Machine Learning

In terms of model development, I am familiar with common practices such as dataset splitting, k-fold cross validation, regularization, hyper-parameter optimization and evaluation metric selection.

I am also very familiar with traditional machine learning approaches such as:

In addition, I have strong knowledge in the implementation of neural networks and enjoy building custom architectures and trying to keep up with the latest advancements in deep learning. While deep learning is fascinating and has its applications, I also spend a lot of time exploring alternatives such as hidden Markov models and Gaussian processes.
