Data Science with Kotlin: Leveraging Deep Analysis with DataFrame

Talkat AndroidMakers by droidcon 2025 · on Friday, 2025-04-11· at 11:15· [kotlin]

Concrete claim: Kotlin DataFrame plus the CSV Gradle library loads and manipulates 1 million rows (reportedly 54 columns) inside an IntelliJ/Jupyter kernel, uses Kotlin data classes interoperability, and runs groupBy/dropNA/aggregation and plotting with lets-plot. Demo shows reading the CSV, dropping nulls from payment_method, counting distinct owners, and drawing a chart; presenter contrasts Kotlin numeric routines as faster than equivalent Python snippets. Some live-build glitches occur but the cleaning, aggregation and plots execute.
