The TAO of data: How Databricks is optimizing AI LLM fine-tuning without data labels

Labeled data is crucial for training AI models but collecting and curating it can be time-consuming and costly for enterprises.
Databricks introduced Test-time Adaptive Optimization (TAO) to fine-tune AI models without the need for labeled data, outperforming traditional methods.
TAO uses reinforcement learning and exploration to optimize models with only example queries, eliminating the need for paired input-output examples.
The approach includes mechanisms like response generation, reward modeling, and continuous data improvement to enhance model performance.
TAO utilizes test-time compute during training without increasing the model's inference cost, making it cost-effective for production deployments.
Databricks' research shows that TAO surpasses traditional fine-tuning methods in terms of performance while requiring less human effort.
TAO has demonstrated significant performance improvements on enterprise benchmarks, approaching the capabilities of more expensive models like GPT-4.
By enabling the deployment of more efficient models with comparable performance and reducing labeling costs, TAO offers a compelling value proposition.
The time-saving element of TAO accelerates AI initiatives by eliminating the lengthy process of collecting and labeling data, thus expediting time-to-market.
Organizations with limited resources for manual labeling but a wealth of unstructured data stand to benefit the most from TAO's capabilities.

9 Database Optimization Tricks SQL Experts Are Hiding From You

In my years of database consultation work, I’ve encountered countless applications buckling under slow queries that could have been fixed with a few targeted optimizations.
Here are nine powerful SQL optimization tricks that can transform your database performance, sometimes by orders of magnitude.
Most developers know about indexes, but few use partial indexes — one of the most powerful ways to speed up specific queries while minimizing index overhead.
A covering index includes all columns needed by a query, allowing the database to satisfy the query using only the index without touching the table at all.

What is a Database? An Introduction

A database is a system that stores information so you can easily find, add, or change it later.
SQL (Structured Query Language) is used to work with databases and manage data.
RDBMS (Relational Database Management System) is the software that manages databases and organizes data in tables.
DDL (Data Definition Language) and DML (Data Manipulation Language) are important components of working with databases.

PL/SQL List to Struct

This post shows you how to take a list of strings and convert them into a struct(ure) of a date, number, and string.
Oracle implements IDL (Interface Description Language), which means the solution requires creating an attribute data type (ADT), a user defined type (UDT), and a collection of the UDT object type.
The code example provides the data definition language (DDL) for the required structures, as well as a function named cast_strings that performs the conversion.
By applying the cast_strings function to a list of strings, you can obtain a struct(ure) object type containing the parsed values of date, number, and string.
