Using AI to drop hats outside my window onto New Yorkers

An enthusiastic dev has implemented an AI-driven "Drop of a Hat" service in midtown NYC, using a Raspberry Pi, an Adafruit stepper motor, and object detection via Roboflow. The system, activated by detecting a person standing in a designated spot for 3 seconds, drops propeller hats onto pedestrians’ heads from their apartment window.

Llama.ttf: A font which is also an LLM

llama.ttf is a unique font file that doubles as a LLM and its inference engine, leveraging the HarfBuzz font shaping engine with Wasm support. This setup allows the font to run inside any Wasm-enabled, HarfBuzz-based application like text editors or email clients, making AI text generation features accessible locally without vendor integration. The implementation hinges on using arbitrary code to handle text shaping, turning symbols into LLM triggers for generating content.

Are LLMs Naturally Good at Synthetic Tabular Data Generation?

LLMs have shown great performance in generating text and images but fall short as synthetic table generators, even with fine-tuning. Their autoregressive nature and random order permutation hinder their ability to model functional dependencies and capture conditional mixtures of distributions. However, by making them permutation-aware, these shortcomings can be mitigated.

Assessing the Emergent Symbolic Reasoning Abilities of LLMs

Open-source LLMs from the Llama 2 family were evaluated on symbolic reasoning tasks involving mathematical formulas. Assessments included a generalist model (Llama 2 Chat) and two fine-tuned versions (MAmmoTH and MetaMath). Results showed that both larger models and task-specific fine-tuning significantly improved performance, especially on simpler formulas. However, even the largest fine-tuned models faced difficulties with these supposedly easier problems.
