Feature Visualization

There is a growing sense that neural networks need to be interpretable to humans. The field of neural network interpretability has formed in response to these concerns. As it matures, two major threads of research have begun to coalesce: feature visualization and attribution. Feature visualization answers questions about what a network — or parts of a network — are […]

#9 – “Institutions Can’t Beat A Basic Buy and Hold Allocation” – Meb Faber Research

Pension funds’ annualized aggregate returns since 2000 have been virtually identical to a simple 60-40 index portfolio.  That feels somewhat expected it seems, but what about the true crème de la crème, the top institutions. Surely they could beat a simple buy and hold allocation? Turns out, they really can’t. Below we recall an article […]

Sequence Modeling with CTC

Introduction Consider speech recognition. We have a dataset of audio clips and corresponding transcripts. Unfortunately, we don’t know how the characters in the transcript align to the audio. This makes training a speech recognizer harder than it might at first seem. Without this alignment, the simple approaches aren’t available to us. We could devise a […]

Safeguarding VS Code against prompt injections

The Copilot Chat extension for VS Code has been evolving rapidly over the past few months, adding a wide range of new features. Its new agent mode lets you use multiple large language models (LLMs), built-in tools, and MCP servers to write code, make commit requests, and integrate with external systems. It’s highly customizable, allowing […]

Using Artificial Intelligence to Augment Human Intelligence

What are computers for? Historically, different answers to this question – that is, different visions of computing – have helped inspire and determine the computing systems humanity has ultimately built. Consider the early electronic computers. ENIAC, the world’s first general-purpose electronic computer, was commissioned to compute artillery firing tables for the United States Army. Other […]
