Training a model that accurately predicts outcomes is great, but most of the time you don't just need predictions, you want to be able to interpret your model. The problem is that the scikit-learn Random Forest feature importance and R's default Random Forest feature importance strategies are biased. To get reliable results in Python, use permutation importance, provided here and in our rfpimp package (via pip). For R, use importance=T in the Random Forest constructor then type=1 in R's importance() function.

Ch 1 Business Forecasting - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. Business forecasting requires skills in economics, statistics, computer applications, and communication. The goal of forecasting is to provide information to reduce uncertainty for decision makers. The forecasting process involves determining the objective, selecting a theoretical model, collecting and analyzing data, estimating models, evaluating models and revising forecasts, presenting forecasts to decision makers, and monitoring forecasts. Understanding business cycles, recession dating procedures, and recent economic performance provides important context for forecasting. Effective forecasting relies on consensus forecasts, monitoring a range rather than single point, understanding forecasting methods, and remaining humble about limitations.

In Joseph Sirosh's keynote presentation at the Data Science Summit on Monday, Wee Hyong Took demonstrated using R in SQL Server 2016 to detect fraud in real-time credit card transactions at a rate of 1 million transactions per second. The demo (which starts at the 17:00 minute mark) used a gradient-boosted tree model to predict the probability of a credit card transaction being fraudulent, based on attributes like the charge amount and the country of origin. Then, a stored procedure in SQL Server 2016 was used to score transactions streaming into the database at a rate of 3.6 billion per...
