LLMs: Lossy Encyclopedias

2025-09-02

Large language models (LLMs) are like lossy encyclopedias; they contain a vast amount of information, but this information is compressed, leading to data loss. The key is discerning which questions LLMs can answer effectively versus those where the lossiness significantly impacts accuracy. For example, asking an LLM to create a Zephyr project skeleton with specific configurations is a 'lossless' question requiring precise details, which LLMs struggle with. The solution is to provide a correct example, allowing the LLM to operate on existing facts rather than relying on potentially missing details within its knowledge base.

New Benchmark Exposes the Automation Bottleneck in OCR: Achieving 98% Precision

2025-03-14

The influx of new OCR players like Mistral and Andrew Ng's offerings makes it hard for enterprises to distinguish genuine advancements from hype. Existing benchmarks focus on OCR accuracy and information extraction, neglecting automation levels. Nanonets introduces a new benchmark emphasizing automation at 98% precision. Using a dataset of 1000 images and 16,639 annotated data points, they measure model performance based on confidence scores – the proportion of data accurately processed without human intervention. While LLMs excel in overall accuracy, reliable confidence scores remain elusive. Gemini 2.0 Flash achieved 98% precision but automated only 8% of the data. This benchmark aims to help enterprises find solutions that truly reduce manual effort in document processing.

Why You Should Leave 100nF Decoupling Capacitors Behind

2025-01-30
Why You Should Leave 100nF Decoupling Capacitors Behind

This article debunks the long-standing practice of using 100nF decoupling capacitors as a default. The author argues that this practice is outdated due to advancements in IC technology (faster switching speeds) and the availability of low-cost, high-capacitance MLCCs. The article dives deep into the physics of decoupling, explaining impedance, parasitic inductance and capacitance, and their impact on power delivery network (PDN) integrity. It advocates for using larger capacitors (1uF or 2.2uF) for better decoupling, reduced EMI, and improved PDN stability. The importance of capacitor package size and its influence on parasitic inductance are highlighted. The author suggests that the persistence of outdated practices stems from cognitive load reduction and historical cost considerations.

Brian Eno's Art Theory and a Dynamic Model of Democracy

This article explores how Brian Eno's art theory illuminates a new understanding of democracy's workings. Drawing on Adam Przeworski's theory of democracy, the author argues that its game-theoretic stability model struggles to explain the current decline of democracy. Eno's concept of 'generating variety' in artistic creation provides inspiration for a more dynamic model of democracy. This model emphasizes adaptability and responsiveness to endogenous change, rather than a rigid equilibrium. The article uses Eno's analysis of music composition as an example to illustrate this dynamic model and calls for a greater emphasis on diversity and adaptability within democratic systems to meet the challenges of complex environments.
