These notes are based on an excellent Intro to Neo4J crash course by Laith Academy these are notes created whilst following along feel free to read but I do highly recommend watching the course too as these notes are provided as is. You can find the sample data for the course here. What is a graph database? A Graph Database is a type of database similar to Relational DB (i.http://lnwatson.co.uk/posts/2d-spectrogram/Sun, 26 May 2024 00:00:00 +0000Authorhttp://lnwatson.co.uk/posts/2d-spectrogram/Understanding Spectrograms A spectrogram is a visual representation of the spectrum of frequencies in a signal as it varies over time. It provides a way to analyse how the frequency content of a signal changes, which is particularly useful in fields such as audio analysis, speech processing, and also seismology (the study of earthquakes). Source: Spectrogram Wikipedia How Spectrograms Work So how do spectrograms work? A spectrogram displays time on the x-axis and frequency on the y-axis.http://lnwatson.co.uk/posts/llm-training-poisoning/Sun, 26 May 2024 00:00:00 +0000Authorhttp://lnwatson.co.uk/posts/llm-training-poisoning/What is a Large Language Model? If you’d like to skip to the poisoned LLM challenge solution click here This is quite a big question and will be covered in detail in its own blog post. Put simply, Large Language Models (LLMs) are advanced AI systems designed to understand and generate human (or ’natural’) language. They are trained on vast amounts of text data, learning patterns, structures, and nuances of language to predict and produce coherent sentences.
