CNN in x86 Assembly: Cat vs Dog Classifier
Read Full Article: CNN in x86 Assembly: Cat vs Dog Classifier
An ambitious project involved implementing a Convolutional Neural Network (CNN) from scratch in x86-64 assembly to classify images of cats and dogs, using a dataset of 25,000 RGB images. The project aimed to deeply understand CNNs by focusing on low-level operations such as memory layout, data movement, and SIMD arithmetic, without relying on any machine learning frameworks or libraries. Key components like Conv2D, MaxPool, Dense layers, activations, forward and backward propagation, and the data loader were developed in pure assembly, achieving a performance approximately 10 times faster than a NumPy version. Despite the challenges of debugging at this scale, the implementation successfully runs inside a lightweight Debian Slim Docker container, showcasing a unique blend of low-level programming and machine learning. This matters because it demonstrates the potential for significant performance improvements in neural networks through low-level optimizations.

Exploring Direct Preference Optimization (DPO)
Read Full Article: Exploring Direct Preference Optimization (DPO)
Direct Preference Optimization (DPO) offers a streamlined and efficient method for aligning large language models (LLMs) with human preferences, bypassing the complexities of traditional reinforcement learning approaches like PPO (Proximal Policy Optimization). Unlike PPO, which involves a multi-component objective and a complex loop of reward modeling and sampling, DPO simplifies the process by directly optimizing a supervised objective on preference pairs through gradient descent. This approach eliminates the need for separate reward model training and the intricate PPO clipping process, making it a more approachable and computationally lightweight alternative. Understanding DPO is crucial as it provides a more straightforward and efficient way to enhance AI models' alignment with human values and preferences.

Training AI Co-Scientists with Rubric Rewards
Read Full Article: Training AI Co-Scientists with Rubric Rewards
Meta has introduced a scalable method to train AI systems to aid scientists in reaching their research objectives by leveraging large language models (LLMs) to extract research goals and grading rubrics from scientific literature. These rubrics are then used in reinforcement learning (RL) training, where the AI self-grades its progress to bridge the generator-verifier gap. Fine-tuning the Qwen3-30B model with this self-grading approach has shown to enhance research plans for 70% of machine learning goals, achieving results comparable to Grok-4-Thinking, though GPT-5-Thinking remains superior. This approach also demonstrates significant cross-domain generalization, supporting the potential of AI as versatile co-scientists. This matters because it highlights the potential for AI to significantly enhance scientific research processes across various domains.

Read Full Article: Pagesource: CLI Tool for Web Dev with LLM Context
Pagesource is a command-line tool designed to capture and dump the runtime sources of a website, providing a more accurate representation of the site's structure for local language model (LLM) context. Unlike the traditional "Save As" feature in browsers that flattens the webpage into a single HTML file, Pagesource preserves the actual file structure, including separate JavaScript modules, CSS files, and lazy-loaded resources. Built on Playwright, it allows developers to access all dynamically loaded JS modules and maintain the original directory structure, making it particularly useful for web developers who need to replicate or analyze website components effectively. This matters because it enhances the ability to work with LLMs by providing them with a more detailed and accurate context of web resources.
