The Measurement Minute #40 with Gary Angel : Small Data Sets are the Real Plague of an Analyst’s Existence

 

We hear a lot about having too much data. But not from analysts – and particularly when it comes to machine learning. Yes, small data sets are still with us.

 

The Measurement Minute #38 with Gary Angel : ML is Changing the Role of the Analyst   Most data analytics folks aren’t ML experts. And like just about everyone else, they’re worried about whether ML and AI will make their jobs redundant.

Gary Angel"

The Measurement Minute #39 with Gary Angel : ML is Deceptively Powerful and Powerfully Deceptive   The most important thing to understand about ML isn’t so much how powerful it is but how limited it is.

The Measurement Minute #37 with Gary Angel : A Brief Thanksgiving Interlude   Ahh snap! The Measurement Minute goes all sappy and philosophical on Thanksgiving. But don’t worry, it will be back to data next time.

The Measurement Minute #36 with Gary Angel : Information is Beautiful…Is Insight?   The 2018 Information is Beautiful Awards have their nominating class – and there are some real knock-outs. But is beauty positively or negatively correlated with insight. The Measurement Minute tackles a question that’s a heckuva lot older than analytics.   Check out … Continue reading "Information is Beautiful…Is Insight? : The Measurement Minute #36 w. Gary Angel"

The Measurement Minute #33 with Gary Angel : Catastrophic Prediction – It’s Not as Bad as it Sounds   It’s nearly impossible to predict the timing and nature of anomalous events – whether they be public health crisis, operational disasters, or insanely viral videos. But by flipping the paradigm from the macro to the micro, … Continue reading "Catastrophic Prediction – It’s Not as Bad as it Sounds : The Measurement Minute #33 w. Gary Angel"

The Measurement Minute #32 with Gary Angel : Predicting Outliers   Outliers are inherently anomalous. So predicting them is pretty much impossible. But you can build a model to help you understand what happens when those outliers occur and how to take advantage of the opportunities they create or mitigate the harm the cause.

The Measurement Minute #31 with Gary Angel : Outliers and Predictive Modeling   My favorite session at the Digital Analytics Hub turned out be a conversation around Predictive Modeling that I got Shanghaied into leading. One of the big topics of discussion turned out be – who would have guessed  – outliers.
