The Machine Learning “Advent Calendar” Day 11: Linear Regression in ExcelTowards Data Science Linear Regression looks simple, but it introduces the core ideas of modern machine learning: loss functions, optimization, gradients, scaling, and interpretation.
In this article, we rebuild Linear Regression in Excel, compare the closed-form solution with Gradient Descent, and see how the coefficients evolve step by step.
This foundation naturally leads to regularization, kernels, classification, and the dual view.
Linear Regression is not just a straight line, but the starting point for many models we will explore next in the Advent Calendar.

Microsoft ‘Promptions’ fix AI prompts failing to deliverAI News Microsoft believes it has a fix for AI prompts being given, the response missing the mark, and the cycle repeating. This inefficiency is a drain on resources. The “trial-and-error loop can feel unpredictable and discouraging,” turning what should be a productivity booster into a time sink. Knowledge workers often spend more time managing the interaction

AI-driven attacks now automate reconnaissance, generate malware variants, and evade detection at a speed that overwhelms traditional defenses. Corelight explains how network detection and response (NDR) provides the visibility and behavioral insights SOC teams need to spot and stop these fast-moving threats. […] Read More
Notepad++ version 8.8.9 was released to fix a security weakness in its WinGUp update tool after researchers and users reported incidents in which the updater retrieved malicious executables instead of legitimate update packages. […] Read More
Hackers are exploiting a new, undocumented vulnerability in the implementation of the cryptographic algorithm present in Gladinet’s CentreStack and Triofox products for secure remote file access and sharing. […] Read More
An unpatched zero-day vulnerability in Gogs, a popular self-hosted Git service, has enabled attackers to gain remote code execution on Internet-facing instances and compromise hundreds of servers. […] Read More
Cybersecurity researchers have disclosed details of a new fully-featured Windows backdoor called NANOREMOTE that uses the Google Drive API for command-and-control (C2) purposes. According to a report from Elastic Security Labs, the malware shares code similarities with another implant codenamed FINALDRAFT (aka Squidoor) that employs Microsoft Graph API for C2. FINALDRAFT is attributed to a Read […]
