I'm speaking at #SubsurfaceLIVE next week on May 2-3, 2024! Dive into data lakehouse innovations with me at Subsurface LIVE 2024, and join 7,000+ global data experts and speakers from Apple, AWS, and more. YouTube Recording: https://lnkd.in/gdK2AeVc #Dremio #Data #SubusrfaceLive As part of my talk, I'll be doing a few technical demos around: - Algebraic matching of reflections into queries - User query rewrites: Aggregate Join Alternative - Viewing refection compute and storage costs through the Reflection Summary UI

If you want to get a peek at some of the secret sauce behind reflections bookmark this talk by Benny Chow #SubsurfaceLIVE Dremio

What is the use of #decisiontree classifiers in the world of #machinelearning? Let us learn it using the following practical approach.  Let us use the following #dataset to build the decision tree and compute Information gain as an attribute selection measure, Gini impurity as an attribute selection measure, and finally results from two different attribute selection measures.

Hey, tech fans! It's Neo here, your favorite digital guide to all things tech! Today, we're diving into the world of databases. Ever wondered how databases keep your data safe and sound? It's all about the ACID properties! Let’s break it down!" A is for Atomicity! C is for Consistency! I is for Isolation! D is for Durability! So, there you have it, folks! The ACID properties ensure your data stays reliable and safe in the digital world. Next time you save a file or complete an online purchase, remember the magic of ACID working behind the scenes! Until next time, stay tech-savvy! #TechTalk #ACIDProperties #Databases #Cybernauts #TechEducation #DatabaseManagement #IT #TechTips #DataIntegrity #DigitalLearning #TechSavvy #Innovation #Technology

The Polytomic release train waits for no one 😄 For those on Databricks, we're announcing support for Delta UniForm ('Universal Format'). Polytomic can now both write to and read from Delta UniForm tables. Delta UniForm is a lakehouse format from our comrades at Databricks designed for automatic compatibility with Delta Lake, Iceberg, and Hudi. This way, rather than having to commit to a single format, you can use Delta UniForm and ensure your lakehouse is compatible with all three (while still having a single copy of your data).

A reminder that users can fetch vector datasets from a multitude of industry leading open source libraries, and in just a couple lines of code. Using the overture(), osm(), and microsoft_ml() method within the Fetch class, users can query against data from OpenStreetMap, @OvertureMaps, and Microsoft ML respectively. Here is a Overture footprint overlayed onto Google's satellite basemap 😍 #Pittsburgh xyzeus #geospatialpy
