Introducing ShipAI | Towards Data Science
Towards Data Science - Mediumby TDS Editors·8 Sept 2026
How do you know an AI project is real? You know it's real when you watch it run. That's the idea behind ShipAI, which is live on TDS today.
Context Windows Don’t Know What’s Still True — I Built a Validity Layer That Does | Towards Data Science
Towards Data Science - Mediumby Emmimal P Alexander·8 Sept 2026
TL;DR I built a working benchmark for this in pure Python. No APIs, no LLMs, just a deterministic setup with real numbers and a runnable repo. The basic problem is simple.
I Vibe-Coded an App in Just Two Hours (And Regretted It the Next Day) | Towards Data Science
Towards Data Science - Mediumby Thuwarakesh Murallie·7 Sept 2026
My daughter is three years old. She broke her toy guitar and wants a new one. Instead of another toy guitar, I bought her a real Ukulele. It's small, lightweight, and perfect for a small girl.
Text Watermarking in Python: Catch Whoever Copies Your Writing | Towards Data Science
Towards Data Science - Mediumby Chien Vu Minh·6 Sept 2026
On August 2, 2026, Anthropic began watermarking every piece of text Claude produces. Since 2024, Gemini (Google) has used SynthID-Text, a method they published in Nature and later open-sourced.
Linear Discriminant Analysis (LDA) in Real-Life: Dimensionality Reduction in a Real-Estate Dataset | Towards Data Science
Towards Data Science - Mediumby Carolina Bento·6 Sept 2026
Linear Discriminant Analysis (LDA) is a supervised learning technique used to surface the core components, or patterns, in the data.
Why Transformers Need Positional Encoding For Time Series: A Visual Guide | Towards Data Science
Towards Data Science - Mediumby Gurjinder Kaur·5 Sept 2026
While digging into foundation models for time series, I realized that I could not really understand them without first understanding transformers.
Dynamical System Transfer Learning with Reduced Order Models | Towards Data Science
Towards Data Science - Mediumby Robert Etter·5 Sept 2026
I have discussed previously the potential utility of applying Reinforcement Learning (RL) to analysis and control of complex physical systems.
Optimal Traffic Allocation Under Heterogeneous Variant Cost | Towards Data Science
Towards Data Science - Mediumby Alejandro Alvarez Perez·4 Sept 2026
What would you do if putting a user in the treatment group cost you twice what it costs to put one in control?
Disaggregation Is a Thousand-GPU Problem | Towards Data Science
Towards Data Science - Mediumby Mostafa Ibrahim·4 Sept 2026
Every major inference framework shipped prefill-decode disaggregation this year. NVIDIA built it into Dynamo. SGLang made it the default for large-scale deployments.
The Power BI Developer's Survival Guide to Microsoft Fabric | Towards Data Science
Towards Data Science - Mediumby Nikola Ilic·4 Sept 2026
I’ve been talking to a lot of Power BI developers in the last 12 months who are truly anxious about Fabric.
How to Run 10+ Claude Code Sessions Without a Powerful Computer | Towards Data Science
Towards Data Science - Mediumby Eivind Kjosbakken·4 Sept 2026
Running coding agents requires a lot of hardware. Of course, running the actual LLM is incredibly expensive and requires extremely powerful GPUs.
My Model Worked Perfectly. Then I Tried to Make It Useful. | Towards Data Science
Towards Data Science - Mediumby Ibrahim Salami·3 Sept 2026
A few months ago, I tried to challenge myself to undertake a journey to transition from a data analytics background to data engineering.
Tables in PDFs for RAG: Don’t Flatten the Grid | Towards Data Science
Towards Data Science - Mediumby Kezhan Shi·3 Sept 2026
The number you need sits in a table, at the intersection of a row and a column. Flatten the PDF to text and that intersection is gone: the label lands in one place, the value in another, and the...
Changing One Prompt Can Affect 50 Others — I Built a Prompt Dependency Graph to Find What Needs Retesting | Towards Data Science
Towards Data Science - Mediumby Emmimal P Alexander·3 Sept 2026
TL;DR If you build with composable prompts, changing one shared component can leave you with a difficult question: what actually needs to be re-evaluated?
How to Solve the Right Problem in the Age of Agentic AI | Towards Data Science
Towards Data Science - Mediumby Mike Huls·3 Sept 2026
Before AI, implementation capacity was scarce. A bad requirement might waste a few engineers' time. With AI, that capacity expands dramatically.
Avoiding Entity Key Drift in a Data Lake: Step 2, When Fuzzy Matching Stops Working | Towards Data Science
Towards Data Science - Mediumby Rahul Saha·2 Sept 2026
Most people who reconcile messy identifiers reach for the same approach: take an edit-distance metric, pick a threshold, and merge anything close enough.
A RAG That Says “Not in This Document” Has to Show Four Kinds of Evidence | Towards Data Science
Towards Data Science - Mediumby Kezhan Shi·2 Sept 2026
The most useful answer a RAG system can give is sometimes “that is not in this document.” But when asked a question, a model tends to answer anyway, so the honest “not found” has to be built in...
Graph Neural Networks: GCN, MPNN, and GAT, Explained Simply | Towards Data Science
Towards Data Science - Mediumby Vyacheslav Efimov·2 Sept 2026
Introduction Neural networks are an incredible innovation. Since a long period of time and up until now, they have been used as a key component in solving complex AI problems.
