A Coding Implementation on MONAI for End-to-End 3D Spleen Segmentation Using UNet on Medical CT Volumes
In this tutorial, we build an end-to-end 3D medical image segmentation pipeline using MONAI to segment the spleen on the Medical Segmentation Decathlon Task09 dataset. We work with volumetric CT scans, apply medical imaging transformations such as orientation alignment, voxel-spacing normalization, intensity windowing, foreground cropping, and patch-based sampling, and then train a 3D UNet model […]
Perplexity Moves Deep Research Into Computer, Routing Research Subtasks Across 20+ Frontier Models For Reports, Decks, And Dashboards
Perplexity has moved Deep Research into Computer, its multi-model orchestration system. The upgrade improves accuracy, depth of analysis, and citation quality. Deep Research now breaks hard questions into subtasks and routes them across 20+ frontier models. It returns work-ready reports, decks, and dashboards, all inside Computer. Deep Research in Computer Deep Research is a mode […]
xAI Ships Grok Build Plugin Marketplace With MongoDB, Vercel, Sentry, Chrome DevTools, Cloudflare, and Superpowers Plugins at Launch
Today, xAI shipped the Grok Build Plugin Marketplace. It is a built-in catalog of plugins for Grok Build, the company’s terminal coding agent. A plugin bundles skills, slash commands, agents, hooks, MCP servers, and LSPs into one package. You browse, install, and update these packages without leaving the terminal. Plugin Marketplace Grok Build is xAI’s […]
BI Is Dead, Long Live BI
The true bottleneck was never the analysis. The post BI Is Dead, Long Live BI appeared first on Towards Data Science. Source link
Stop Returning Flat Text from a PDF: The Relational Shape RAG Needs
brick of Enterprise Document Intelligence, a series that builds an enterprise RAG system from four bricks: parsing, question parsing, retrieval, and generation. Parsing comes first, and this is the second of its two parts. The previous part turned a PDF into line_df, one row per line of text on the page. This one covers the […]
PySpark for Beginners: Beyond the Basics
in this series, PySpark for Beginners: Mastering the Basics then you already understand the heart of Spark: distributed data, DataFrames, and lazy execution. You’ve installed PySpark, stood up a SparkSession, read a CSV and performed simple manipulations of the data in a Dataframe. I’ll leave a link to that story at the end of this […]
When GPU Utilization Lies: The Hidden Systems Problem Slowing Modern AI
team gets pinged because inference latency has suddenly jumped by 60%. The dashboards are confusing. GPU utilization still looks healthy: Nothing appears catastrophically wrong. Autoscaling kicks in. More nodes are added. The cloud bill climbs. Latency barely improves. An hour later, the real problem turns out to be surprisingly mundane: three nodes quietly entered degraded […]
Multi-Label Text Classification with Scikit-LLM
In this article, you will learn how to perform multi-label text classification using large language models and the scikit-LLM library, without the need for labeled training data or complex model training. Topics we will cover include: What multi-label classification is and why it matters for nuanced text analysis. How to set up and configure scikit-LLM […]
NuCS vs Choco: A Pure-Python Constraint Solver Meets a JVM Veteran
NuCS is a constraint solver written 100% in Python, developed by me, accelerated by NumPy and Numba. Choco is one of the reference open-source constraint solvers, written in Java and developed for more than two decades. Comparing them looks lopsided: an interpreted language against a heavily optimized JVM solver with a rich catalog of arc-consistent global constraints. The reality is more interesting. When both solvers run the same model they […]
Visa ChatGPT integration enables AI agent retail purchasing
Visa has linked its payment infrastructure to ChatGPT, enabling AI agents to recommend retail products and execute financial transactions. The deployment removes human intervention from the final stages of the retail funnel. Autonomous agents will now process user prompts, evaluate merchant catalogues, and complete the checkout process using Visa’s payment rails at any supporting merchant. […]
