See you later! :)</p> <p>***</p> <p>We have two great speakers - and they are excited to share their expertise! Come to learn and meet new people in cosy and warm atmosphere :)</p> <p>FIRST TALK:<br/>Our first speaker is Shihan Du. She has a PhD in applied econometrics, recently graduated from Copenhagen Business School, and is now working as a part-time researcher at China-Europe Productivity Center.</p> <p>Shihan's presentation is about advanced regression frameworks on decomposition techniques to analyze reasons for customer retention. Shihan will show one of her PhD projects - the Oaxaca-Blinder decomposition and decomposition based on conditional quantiles(non-linear), performed on individual-level data from Statistic Denmark. Principal component analysis (PCA) will also be briefly discussed at the end of the presentation.</p> <p>SECOND TALK:<br/>Our second speaker is Peer Christensen, who has a backround in linguistics and cognitive science. While working towards a PhD, he became interested in pursuing a career as a data scientist and spent much time learning R and Python. Peer recently started working at Saxo.com where he finds new ways of leveraging customer and product data to create insights.</p> <p>Predicting customer churn is a special case of binary classification, where standard measures of predictive accuracy are misleading when true positive predictions (churn = yes) are more important than true negatives (churn = no).</p> <p>Peer will show some of his ongoing work using R and the H2O autoML framework to train and evaluate multiple models in terms of their usefulness in a real-world use case.</p> <p>SAVE THE DATE!:<br/>When: December 5<br/>Time: 17:30 - 19:30<br/>Where: Niels Brock<br/>Bispetorvet 3<br/>1167 Copenhagen</p> <p>See you all soon!</p> <p>Regards,<br/>RLadies CPH<br/>Ivana, Shihan, Peer, Sharon</p>
