Data.table for R and Python - Matt Dowle - H2O AI World London
This talk was recorded in London on October 30th, 2018.
Matt created the data.table package for R 10 years ago. It provides a high-performance version of R's data.frame with syntax and feature enhancements for ease of use, convenience and programming speed. It now has 8,000 questions on Stack Overflow, peaks at 400k downloads per month, and has 650 CRAN and Bioconductor packages using it.
H2O employs Matt full time and supports his continued work on data.table. H2O has rewritten datatable for Python which is now available open-source. The Python package datatable is used by Driverless AI. Matt will present recent advances in data.table for R and datatable for Python.
Matt is the main author of the data.table package in R. He has worked for some of the world’s largest financial organizations: Lehman Brothers, Salomon Brothers, Citigroup, Concordia Advisors and Winton Capital. He is particularly pleased that data.table is also used outside Finance, for example Genomics where large and ordered datasets are also researched.
Matt has been programming in S/R for 15 years, knows C pretty well and holds a first class BSc in Applied Maths and Computing from Warwick University, U.K.
