The Machine Learning “Advent Calendar” Day 19: Bagging in Excel

For 18 days, we've got explored many of the core machine learning models, organized into three major families: distance- and density-based models, tree- or rule-based models, and weight-based models. Up so far, each article focused...

The Machine Learning “Advent Calendar” Day 18: Neural Network Classifier in Excel

Neural Network Regressor, we now move to the classifier version. From a mathematical viewpoint, the 2 models are very similar. In truth, they differ mainly by the interpretation of the output and the selection...

A Practical Toolkit for Time Series Anomaly Detection, Using Python

fascinating points of time series is the intrinsic complexity of such an apparently easy kind of information. At the tip of the day, in time series, you've an x axis that typically represents time...

The Machine Learning “Advent Calendar” Day 14: Softmax Regression in Excel

With Logistic Regression, we learned classify into two classes. Now, what happens if there are greater than two classes. n is just the multiclass extension of this concept. And we are going to discuss this...

The Skills That Bridge Technical Work and Business Impact

In “What ‘Pondering’ and ‘Reasoning’ Really Mean in AI and LLMs,” you address the semantic gap between human and machine reasoning. How does understanding this distinction impact the way in which you approach model...

The Machine Learning “Advent Calendar” Day 13: LASSO and Ridge Regression in Excel

Someday, a knowledge scientist told that Ridge Regression was an advanced model. Because he saw that the training formula is more complicated. Well, this is precisely the target of my Machine Learning “Advent Calendar”, to...
