Christopher Samiullah, Soledad Galli: Testing and Validating Machine Learning Models when Deploying to Production PyData London 2019 Slides - https://www.slideshare.net/solegalli2... Through model deployment, we bridge the gap between the research environment and live systems. Reproducibility between environments is key to maximise the researched value the ML models will bring to an organisation. Therefore, before the models are fully integrated and live, we run thorough testing and reconciliation processes. PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other.
