Kalman Filter Explained Through Examples

0 CommentsEntertainment

🔥 Read this insightful post from Hacker News 📖 📂 **Category**: 📌 **What You’ll Learn**: Kalman Filter example Let us begin with a simple example: a one-dimensional radar that measures range and velocity by transmitting a pulse toward an aircraft and receiving the reflected echo. The time delay between pulse transmission and echo reception provides information about the aircraft range \(r\), and the frequency shift of the reflected echo provides information about the aircraft velocity \(v\) (Doppler effect). In this example, the system state is described by both the aircraft range \(r\) and velocity \(v\).…

Introducing Muse Spark: Scaling Towards Personal Superintelligence

0 CommentsEntertainment

✨ Discover this must-read post from Hacker News 📖 📂 **Category**: 💡 **What You’ll Learn**: To build personal superintelligence, our model’s capabilities should scale predictably and efficiently. Below, we share how we study and track Muse Spark's scaling properties along three axes: pretraining, reinforcement learning, and test-time reasoning.Pretraining. The pretraining phase is where Muse Spark acquires its core multimodal understanding, reasoning, and coding abilities — the foundation that reinforcement learning and test-time compute build upon.Over the last nine months, we rebuilt our pretraining stack with improvements to model architecture, optimization, and data curation. Together, these advancements increase the capability we…

rvitorper/go-bt: Minimalist BT implementation in Go · GitHub

0 CommentsEntertainment

🔥 Explore this awesome post from Hacker News 📖 📂 **Category**: ✅ **What You’ll Learn**: go-bt is a Behavior Tree library for Go. Designed for background workers, game AI, mundane task automation, and asynchronous logic. Instead of time.Sleep or infinite while loops, go-bt uses a cooperative multitasking model. Nodes return state instantly, yielding control back to the supervisor. Stateless Nodes: Nodes (Sequence, Selector, etc.) do not hold runtime state. All temporal memory and execution states live entirely within the generic BTContext[T]. The Magic Numbers: Every node's Run method returns exactly one of three integers: 1 (Success): The task is done…

The only traces left of the original are a few drawings and handwritten notes. Back then, writing for an 8-bit platform, it took every bit of memory and CPU to eke out 4 frames/s with the simplest of animations and backgrounds. Alas, by the time I finished it, the 1990 recession had begun, affecting many industries,…
