Machine Learning Cheat Sheet Bundle, Which Algorithm, Model Evaluation Metrics, Cross Validation, Data Science Study Guide

Seller's description

A machine learning cheat sheet bundle: which algorithm to try, how to evaluate it, and how to validate it without leakage, 12 pages.
THIS IS A DIGITAL DOWNLOAD. NO PHYSICAL ITEM WILL BE SHIPPED.
You will receive printable PDF files in one ZIP file. No printed or laminated sheets are included. The photos show how they look once printed.

THREE STUDY GUIDES, THREE QUESTIONS
Which model should I try? Does it work? Can I trust the score? Three of our visual machine learning study guides answer them in order, in one download and at a lower price than buying them separately. Each one is two sheets, printed on both sides (4 pages), with a Test Yourself version. Every chart, boundary and number is computed from real fitted models on small made-up data sets. No code on the sheets: pictures, a little maths and decision charts.

1. SUPERVISED MACHINE LEARNING: WHICH ALGORITHM SHOULD I USE? (4 pages)
- supervised learning in one picture, a starting loop (baseline, simple model, validate, diagnose), the three data roles
- linear and logistic regression, naive Bayes and k-nearest neighbours, each with its boundary on the same plants
- decision trees, random forest, gradient boosting and support vector machines
- eight algorithms side by side, too simple or too complex, and where to start

2. MODEL EVALUATION & METRICS (4 pages)
- the confusion matrix in the problem's own words, six metric tiles and a "Which metric?" decision chart
- moving the threshold: four thresholds, costs, F1 and F-beta
- ROC and PR curves, AUC and average precision, calibration, Brier score and log loss
- regression metrics (MAE, RMSE, R squared), more than two classes, and an honest report

3. TRAINING, VALIDATION & LEAKAGE (4 pages)
- "Which split matches the future?": random, grouped and forward splits; training, validation and test
- reading the gap: underfitting, overfitting, bias and variance, cross-validation and tuning
- six kinds of leakage, each with a flawed and a corrected score
- the safe order from the first split to the report, and "Too good to be true?" checks

TEST YOURSELF VERSIONS
Every sheet also comes with its Test Yourself version: the same pages with the answers left blank. Fill them in from memory, then check yourself against the cheat sheet.

WHAT YOU GET: 24 PDF FILES (in one ZIP, one folder per cheat sheet)
- 3 cheat sheets, each as Cheat Sheet and Test Yourself
- 2 styles: Color, and Gray (uses less coloured ink)
- 2 paper sizes: A4 and US Letter
- each file is two sheets: 4 pages, print double-sided ("flip on long edge")
- a short READ ME with printing tips

WHO IT IS FOR
Students in a first machine learning or data science course, bootcamp students, analysts moving into machine learning, and anyone preparing for data science interviews.

HOW IT IS MADE
Typeset in LaTeX; every chart and number is computed by code from real fitted models, no AI image generator was used. The data is invented for teaching. The content and the code were prepared with help from an AI assistant; every number was checked by a script, and the sheets were reviewed.

HOW IT WORKS
1. Purchase the listing.
2. Download the ZIP file instantly from Purchases & Reviews in your Etsy account (or from the link in your confirmation email) and unzip it.
3. Print at home or at a print shop at 100% / "actual size", double-sided, or open the PDF on a tablet.

PLEASE NOTE
- This is a digital product. Nothing will be shipped.
- These are the same files as our Supervised Machine Learning, Model Evaluation & Metrics and Training, Validation & Leakage cheat sheet listings: no need to buy those as well.
- Due to the nature of digital downloads, refunds are not accepted. Send us a message if you have any problem with your files and we'll gladly help.
- Colours may vary slightly between screens and printers.
- For personal use only. You may print as many copies as you need for yourself. Teachers: please message us about classroom use. Reselling or sharing the files is not allowed. (c) MIRAICO Academy, all rights reserved.

Also in the shop: the Math for Machine Learning bundle (linear algebra, derivatives, probability, statistics).

At MiraicoAcademy, we compute every chart from real models, so the ideas are easy to see.
