Model Tuning and the Bias-Variance Tradeoff | A VISUAL INTRODUCTION TO MACHINE LEARNING PART II
A visual introduction to machine learning—Part II Model Tuning and the Bias-Variance Tradeoff The goal of modeling is to approximate real-life situations by identifying and encoding patterns in data. Models make mistakes if those patterns are overly simple or overly complex. In Part 1, we created a model that distinguishes homes in San Francisco from those in New York. Now, we'll talk about tuning

Utilization Heat Maps
Device utilization is a key metric for performance analysis and capacity planning. On this page I'll illustrate different ways to visualize device utilization across multiple devices, and how that utilization is changing over time. As a system to study, I'll examine a production cloud environment that contains over 5,000 virtual CPUs (over 600 physical processors). I'll show how well different vis
Postgres Query Plan Visualization - tatiyants.com
After a recent stint in query optimization, I once again found myself wanting a better way to view query plans produced by EXPLAIN. So, I finally decided to do something about it and the result is Postgres EXPLAIN Visualizer (or Pev): Why Pev I wanted a tool that can make plans simple to understand and be visually pleasing. More specifically, I wanted: minimal visual noise insights high degree of

Explain Git with D3
We are going to skip instructing you on how to add your files for commit in this explanation. Let's assume you already know how to do that. If you don't, go read some other tutorials. Pretend that you already have your files staged for commit and enter git commit as many times as you like in the terminal box. git branch name will create a new branch named "name". Creating branches just creates a n
