Recently, due to some serendipitous events, I had a chance to modify the architecture of a model slightly. I took this opportunity to explore how to iterate and print the layers of neural networks in PyTorch.

Softmax is a commonly used activation function, and it is often employed as the last layer in multi-class classification.
Triton is an open-source GPU programming language compiler released by OpenAI in 2021. Over recent years, it has become increasingly popular among developers for writing and optimizing parallel programs on GPUs. Compared to traditional libraries such as CUDA or OpenCL, Triton offers a Python-like syntax, making it more readable and easier to learn.

My advisor used to tell me, “Don't just use other people's libraries; you have to write your own to truly understand.” Back then, I didn’t have much time to implement various technologies I was interested in since I was fully occupied with my dissertation. However, I often recall his earnest advice even now, and it prompted me to finally attempt the implementation of BERT, a classic encoder-only transformer model.

Recently, I integrated several applications of Outlines into my current workflow. Among them, the one I use most frequently is with vLLM. However, for some reason, its documentation has not been merged into the vLLM GitHub repository, so while designing the process, I had to constantly refer to the source code of a rejected PR for guidance XD

This is a simple Python implementation, used to test Finite-State Machine (FSM) constraints for a Large Language Model (LLM) to decode responses in a specific format. It also serves as an introduction to the concept behind the Outlines tool. Of course, my implementation is far simpler compared to the actual Outlines tool.

When applying Large Language Models (LLMs) in real-world scenarios, it's often not just about letting the model generate text freely. We might want the model to return specific structures, such as multiple-choice questions or providing a rating. In such cases, transformers-based models can directly use the outlines tool.

Generative models are becoming increasingly powerful, and independent researchers are deploying one open-source large language model (LLMs) after another. However, when using LLMs for inference or generating responses, waiting for a longer output can be quite time-consuming.

Variational AutoEncoder (VAE) is an advanced variant of the AutoEncoder (AE). The architecture is similar to the original AutoEncoder, consisting of an encoder and a decoder.

Currently, LLM services cover a wide range of fields, and Prompt Injection and Jailbreak threats to LLMs are growing by the day. A few months ago, a customer service LLM even provided incorrect information, leading to a loss of customer rights (although that wasn't caused by a prompt attack).
Microsoft's open-source BIPIA (Benchmarking and Defending Against Indirect Prompt Injection Attacks on Large Language Models) evaluation method, although tested six months ago without significant updates since, remains a simple and convenient testing method for the tasks I have at hand.
