Error correction tolerant quantum computing

The Lindahl Letter ·

2024/12/28

Quantum computing has long been hailed as a transformative technology with the potential to revolutionize fields such as cryptography, optimization, material science, and beyond [1]. However, quantum computing faces a fundamental challenge: the fragility of quantum states. Quantum bits, or qubits, are extraordinarily sensitive to errors caused by environmental noise, decoherence, and operational inaccuracies. Without robust error correction, this fragility undermines the reliability of quantum

We are going to spend some time digging into quantum computing over the next few weeks. Things are starting to move forward in that space which is exciting [1]. Let’s not waste a second and just go ahead and jump right into the deep end of this magical quantum puzzle. Here we go!Nondeterministic gates present a fascinating challenge within the evolving landscape of quantum computing. At their core, these gates function probabilistically, meaning their outcomes are not guaranteed in the deterministic

Transfer Learning for Features

The Lindahl Letter ·

2024/12/14

Transfer learning has proven to be an invaluable tool in machine learning, enabling us to take advantage of pre-trained models to boost performance on new tasks, even with limited data. Instead of training a model from scratch, we can repurpose one trained on a large, diverse dataset to extract features—essential characteristics of the data—that are often applicable across various problems. For instance, in image recognition, these features might be edges, textures, or patterns that the model has

Graph-Based Feature Engineering

The Lindahl Letter ·

2024/12/07

As machine learning evolves, traditional approaches to feature engineering are being transformed by the power of graph data structures. Graphs—representing entities as nodes and relationships as edges—provide a rich framework to model complex, non-linear connections that go beyond what’s possible with tabular data. It’s an area of focus I keep going back to better represent knowledge. By embracing graph-based feature engineering, we can uncover deeper insights and create more effective predictive

Enabling automated agent actions

The Lindahl Letter ·

2024/11/16

We all thought you would be able to easily ask the house to turn on all the lights or command your television by voice to do things by walking into the room. Some of us thought the entire wall would be a television screen by now and that has not happened either. However, some of the new 100 inch TVs on the market are really large. Enabling automated actions is what is happening within the latest development kits related to the companies making and contributing to LLMs. We have seen Google teams

Where does AI fit within Archeology?

The Lindahl Letter ·

2024/11/09

This post is all Dr. Flint Dibble’s fault. That fault is wholesale based on all the #realarchaeology posts that have been flying around the internet [1]. If you missed all that online content about archaeology, then consider diving into all that informationally rich real archeology content. This week Flint got me thinking about how artificial intelligence and machine learning fit within the broader academic domain of archaeology. Technology is always approaching the intersection with modernity. Our
