Detecting Bias with SHAP
StackOverflow's annual developer survey concluded earlier this year, and they have graciously published the (anonymized) 2019 results for analysis. They're a rich view into the experience of software developers around the world -- what's their favorite editor? how many years of experience? tabs or spaces? and crucially, salary. Software engineers' salaries are good, and sometimes...
Announcing the MLflow 1.0 Release
MLflow is an open source platform to help manage the complete machine learning lifecycle. With MLflow, data scientists can track and share experiments locally (on a laptop) or remotely (in the cloud), package and share models across frameworks, and deploy models virtually anywhere. Today we are excited to announce the release of MLflow 1.0. Since...
Hyperparameter Tuning with MLflow, Apache Spark MLlib and Hyperopt
Hyperparameter tuning is a common technique to optimize machine learning models based on hyperparameters, or configurations that are not learned during model training. Tuning these configurations can dramatically improve model performance. However, hyperparameter tuning can be computationally expensive, slow, and unintuitive even for experts. Databricks Runtime 5.4 and 5.4 ML (Azure | AWS) introduce new...
Advanced Analytics with HyperLogLog Functions in Apache Spark
This is a community guest blog from Sim Simeonov, the founder & CTO of Swoop and IPM.ai. Pre-aggregation is a common technique in the high-performance analytics toolbox. For example, 10 billion rows of website visitation data per hour may be reducible to 10 million rows of visit counts, aggregated by the superset of dimensions used...

Detecting Financial Fraud at Scale with Decision Trees and MLflow on Databricks
Detecting fraudulent patterns at scale is a challenge, no matter the use case. The massive amounts of data to sift through, the complexity of the constantly evolving techniques, and the very small number of actual examples of fraudulent behavior are comparable to finding a needle in a haystack while not knowing what the needle looks...
Understanding Dynamic Time Warping
This blog is part 1 of our two-part series Using Dynamic Time Warping and MLflow to Detect Sales Trends. To go to part 2, go to Using Dynamic Time Warping and MLflow to Detect Sales Trends. The phrase “dynamic time warping,” at first read, might evoke images of Marty McFly driving his DeLorean at 88...
Using Dynamic Time Warping and MLflow to Detect Sales Trends
This blog is part 2 of our two-part series Using Dynamic Time Warping and MLflow to Detect Sales Trends. The phrase “dynamic time warping,” at first read, might evoke images of Marty McFly driving his DeLorean at 88 MPH in the Back to the Future series. Alas, dynamic time warping does not involve time travel; instead, it’s...
A Guide to Healthcare and Life Sciences Talks at Spark + AI Summit 2019
Data and AI are ushering in a new era of precision medicine. The scale of the cloud, combined with advancements in machine learning, are enabling healthcare and life sciences organizations to use their mountains of data—such as electronic health records, genomics, real-world evidence, claims, and more—to drive innovation across the entire ecosystem, from accelerating drug...
