What would an FBI profiler conclude about LLMs? Part 4 of my LLM-profiling series: tbartzbe.substack.com/p/fbi-profil...

FBI Profiling for LLMs In 1941 Cleckley described patients who were charming, intelligent, rational, and untrustworthy to the core. Part 3 of my FBI-profiling series: his 16 items, from superficial charm to no life plan, as an instrument for LLMs. tbartzbe.substack.com/p/fbi-profil...

FBI Profiling for LLMs, Part 2 How do you analyze a black-box automaton that cannot be opened? tbartzbe.substack.com/p/fbi-profil...

Profiling LLMs In the 1970s, FBI special agents at Quantico developed a radically new investigative methodology. The paradigm shift was to treat behaviour itself as evidence. I will apply this to LLMs. Started as a fun project... results are frightening. tbartzbe.substack.com/p/fbi-profil...

Just realized BlueSky allows sharing valuable stuff cause it doesn't punish links. 🤩 Let's start with "What are embeddings" by @vickiboykis.com The book is a great summary of embeddings, from history to modern approaches. The best part: it's free. Link: vickiboykis.com/what_are_emb...
Book outlineOver the past decade, embeddings — numerical representations of
machine learning features used as input to deep learning models — have
become a foundational data structure in industrial machine learning
systems. TF-IDF, PCA, and one-hot encoding have always been key tools
in machine learning systems as ways to compress and make sense of
large amounts of textual data. However, traditional approaches were
limited in the amount of context they could reason about with increasing
amounts of data. As the volume, velocity, and variety of data captured
by modern applications has exploded, creating approaches specifically
tailored to scale has become increasingly important.
Google’s Word2Vec paper made an important step in moving from
simple statistical representations to semantic meaning of words. The
subsequent rise of the Transformer architecture and transfer learning, as
well as the latest surge in generative methods has enabled the growth
of embeddings as a foundational machine learning data structure. This
survey paper aims to provide a deep dive into what embeddings are,
their history, and usage patterns in industry.Cover image
