Managing large hierarchical datasets with PyTables

Walter C. Koerner Library 1958 Main Mall, Vancouver, British Columbia, Canada

Abstract: PyTables is a free and open-source Python library for managing large hierarchical datasets. It is built on top of numpy and the HDF5 scientific dataset library, and it focuses both on performance and interactive analysis of very large datasets. For large data streams (think multi-dimensional arrays or billions of records) it outperforms databases in […]

Machine Learning: Finding pre-trained models for transfer learning

Online/Virtual Event

Abstract: Training models from scratch requires way too much data, time, and computing power (or money) to be a practical option. This is why transfer learning has become such a common practice: by starting with models trained on related problems, you are saving time and achieving good results with little data. Now, where do you […]

Python for simple data visualizations

Online/Virtual Event

Abstract: Building on our two previous Python workshops, today we will look at various packages to do simple plotting and data visualization in Python. In the hands-on part, we will focus on matplotlib which is a well-established Python plotting library for for creating static and animated visualizations in Python. Setup & Software Installation: You need […]

Web scraping with Python

Online/Virtual Event

Abstract: The internet is a trove of information. A lot of it is publicly available and thus suitable for use in research. Extracting that information and putting it in an organized format for analysis can however be extremely tedious. Web scraping tools allow to automate parts of that process and Python is a popular language […]
