The Machine Learning “Advent Calendar” Day 18: Neural Network Classifier in ExcelTowards Data Science Neural networks are often presented as black boxes, hidden behind high-level libraries and abstract concepts.
In this article, we build a neural network classifier from scratch using Excel, with every computation written explicitly.
Starting from forward propagation and ending with backpropagation, we show how the model is defined as a simple mathematical function and how its parameters are learned using gradient descent. No shortcuts, no hidden steps, just the mechanics that make neural networks work.

Prompt Engineering for Data Quality and Validation ChecksKDnuggets Prompt engineering is not just about asking models the right questions — it is about structuring those questions to think like a data auditor. When used correctly, it can make quality assurance faster, smarter, and far more adaptable than traditional scripts.

Evaluating chain-of-thought monitorabilityOpenAI News OpenAI introduces a new framework and evaluation suite for chain-of-thought monitorability, covering 13 evaluations across 24 environments. Our findings show that monitoring a model’s internal reasoning is far more effective than monitoring outputs alone, offering a promising path toward scalable control as AI systems grow more capable.
