Ceteris Paribus v0.3 is on CRAN

Ceteris Paribus package is a part of DALEX family of model explainers. Version 0.3 just gets to CRAN. It’s equipped with new functions for very elastic visual exploration of black box models. Its grammar generalizes Partial Dependency Plots, Individual Conditional Expectations, Wangkardu Plots and gives a lot of flexibility in model comparisons, groups comparisons and … Czytaj dalej Ceteris...

No worries! Afterthoughts from UseR 2018

This year the UseR conference took place in Brisbane, Australia. UseR is my favorite conference and this one was mine 11th (counting from Dortmund 2008).  Every UseR is unique. Every UseR is great. But my feelings are that European UseRs are (on average) more about math, statistics and methodology while US UseRs are more about … Czytaj dalej No...

Local Goodness-of-Fit Plots / Wangkardu Explanations – a new DALEX companion

The next DALEX workshop will take place in 4 days at UseR. In the meantime I am working on a new explainer for a single observation. Something like a diagnostic plot for a single observation. Something that extends Ceteris Paribus Plots. Something similar to Individual Conditional Expectation (ICE) Plots. An experimental version is implemented in ceterisParibus … Czytaj dalej Local...

modelDown: a website generator for your predictive models

I love the pkgdown package. With a single line of code you can create a complete website with examples, vignettes and documentation for your package. Brilliant! So what about a website generator for predictive models? Imagine that you can take a set of predictive models (generated with caret, mlr, glm, xgboost or randomForest, anything) and … Czytaj dalej modelDown:...

Not only LIME

I’ve heard about a number of consulting companies, that decided to use simple linear model instead of a black box model with higher performance, because ,,client wants to understand factors that drive the prediction’’. And usually the discussion goes as following: ,,We have tried LIME for our black-box model, it is great, but it is … Czytaj dalej Not...

Ceteris Paribus Plots – a new DALEX companion

If you like magical incantations in Data Science, please welcome the Ceteris Paribus Plots. Otherwise feel free to call them What-If Plots. Ceteris Paribus (latin for all else unchanged) Plots explain complex Machine Learning models around a single observation. They supplement tools like breakDown, Shapley values, LIME or LIVE. In addition to feature importance/feature attribution, … Czytaj dalej Ceteris...

ML models: What they can’t learn?

What I love in conferences are the people, that come after your talk and say: It would be cool to add XYZ to your package/method/theorem. After the eRum (great conference by the way) I was lucky to hear from Tal Galili: It would be cool to use DALEX for teaching, to show how different ML … Czytaj dalej ML...

DALEX Stories – Warsaw apartments

This Monday we had a machine learning oriented meeting of Warsaw R Users. Prof Bernd Bischl from LMU gave an excellent overview of mlr package (machine learning in R), then I introduced DALEX (Descriptive mAchine Learning EXplanations) and Mateusz Staniak introduced live and breakDown packages. The meeting pushed me to write down a gentle introduction … Czytaj dalej DALEX...

DALEX: which variables are really important? Ask your black box model!

Third post from the short series about black-box explainers implemented in the DALEX package. Learn more about DALEX at SER (Warsaw, April 2018), eRum (Budapest, May 2018), WhyR (Wroclaw, June 2018) or UseR (Brisbane, July 2018). Two weeks ago I wrote about single variable conditional responses and last week I wrote about decompositions of a … Czytaj dalej DALEX:...
