Data Poisoning in Machine Learning: Why and How People Manipulate Training Data

missed but hugely vital a part of enabling machine learning and subsequently AI to operate. Generative AI corporations are scouring the world for more data continuously because this raw material is required in...

Drift Detection in Robust Machine Learning Systems

was co-authored by Sebastian Humberg and Morris Stallmann. Introduction      Machine learning (ML) models are designed to make accurate predictions based on patterns in historical data. But what if these patterns change overnight? For...

The Machine Learning “Advent Calendar” Bonus 2: Gradient Descent Variants in Excel

use gradient descent to seek out the optimal values of their weights. Linear regression, logistic regression, neural networks, and enormous language models all depend on this principle. Within the previous articles, we used...

The Machine Learning “Advent Calendar” Bonus 1: AUC in Excel

, we'll implement AUC in Excel. AUC is normally used for classification tasks as a performance metric. But we start with a confusion matrix, because that's where everyone begins in practice. Then we'll see why a...

Machine Learning vs AI Engineer: What Are the Differences?

confusing questions in tech straight away is: Each are six-figure jobs, but when you select the flawed one, you can waste months of your profession learning the flawed skills and miss out on quality...

The Machine Learning “Advent Calendar” Day 24: Transformers for Text in Excel

of my Machine Learning Advent Calendar. Before closing this series, I would really like to sincerely thank everyone who followed it, shared feedback, and supported it, specifically the Towards Data Science team. Ending this calendar...

The Machine Learning “Advent Calendar” Day 23: CNN in Excel

were first introduced for images, and for images they are sometimes easy to know. A filter slides over pixels and detects edges, shapes, or textures. You possibly can read this text I wrote earlier...

The Machine Learning “Advent Calendar” Day 20: Gradient Boosted Linear Regression in Excel

, we ensemble learning with voting, bagging and Random Forest. Voting itself is simply an aggregation mechanism. It doesn't create diversity, but combines predictions from already different models.Bagging, however, explicitly creates diversity by training...
