- 24. How to find the right algorithm? The Internet… - the resource - do you define the source as trusted? (eg. scikit-learn) - number of stars, forks, when was the last commit? (GitHub) - the code - is it aligned with the Python standards? (PEP 8) - check the particular functions - ... - does it fit to the general architecture of a project? - ask a friend Anna Gut, Python Developer & Team Lead @10Clouds EuroPython 2018 Kamila Stępniowska, CC-BY
- 25. Hacks - what was your steps & how did you get there Step is a wrapper over the transformer and handles multiple aspects of the execution of the pipeline, such as saving intermediate results (if needed), checkpointing the model during training and more. Transformer is purely computational, data scientist-defined piece that takes an input data and produces some output data. Typical Transformers are neural network, machine learning algorithms and pre- or post-processing routines. github.com/neptune-ml/steppy EuroPython 2018 Kamila Stępniowska, CC-BY
