Why Randomization is Key When Splitting Data for Machine Learning

Post:
Essentially, Machine Learning is about learning from data. Having "good" data leads to better models, and more importantly, the quality of the information being used plays a crucial role in improving prediction accuracy.

Hey Developers,

Hi Everyone, I'm Prakash Hinduja, a financial advisor and consultant. My roots in India now living in Geneva, Switzerland (Swiss). I'm looking for some suggestions on how to get the best performance from Adaptive Analytics 2023.2. I know it uses Adaptive Parallel Execution and automatic aggregates, but I'm curious if you've found any other tips or tricks. For example, are there any specific data modeling choices or system configurations that have worked well for you? I'm trying to make our cubes as responsive as possible. Thanks in advance for any insights!

Regards

In this final part of our introduction to Window Functions, we will explore the remaining functions that have not been covered yet. You will also discover performance tips and a practical guide to help you decide when (and when not) to use window functions effectively.

1. Offset and Positional Value Functions

Overview

These functions reference values are calculated from other rows relative to the current row, or they are extracted from the first, last, or nth values within a window.

Hello!

I'm trying to create some foreign tables to a PostgreSQL database. In some cases, columns with certain datatypes cannot be consumed by IRIS and the following error is thrown:

[SQLCODE: <-237>:<Schema import for foreign table did not return column metadata>]

[%msg: <Unkown data type returned by external database>]

For example: serial4 typed ID columns are typical examples. Is it possible, what's the best way of resolving these datatypes, which- seemingly- don't have proper JDBC metadata mappings?

I want to build an event store using raw globals and replay events for rebuilding state. Can I hook into IRIS journaling or write my own event log and replay engine?
