Ghostbuster: Detecting Text Ghostwritten by Large Language Models

stp2y0 CommentsAIlarge language models, text generation

The structure of Ghostbuster, our new state-of-the-art method for detecting AI-generated text. Large language models like ChatGPT write impressively well—so well, in fact, that they’ve become a problem. Students have begun using these models to ghostwrite assignments, leading some schools to ban ChatGPT. In addition, these models are also prone to producing text with factual errors, so wary readers may want to know if generative AI tools have been used to ghostwrite news articles or other sources before trusting them. What can teachers and consumers do? Existing tools to detect AI-generated text sometimes do poorly on data that differs from…

Create a multimodal assistant with advanced RAG and Amazon Bedrock | Amazon Web Services

stp2y0 CommentsAI

Retrieval Augmented Generation (RAG) models have emerged as a promising approach to enhance the capabilities of language models by incorporating external knowledge from large text corpora. However, despite their impressive performance in various natural language processing tasks, RAG models still face several limitations that need to be addressed. Naive RAG models face limitations such as missing content, reasoning mismatch, and challenges in handling multimodal data. Although they can retrieve relevant information, they may struggle to generate complete and coherent responses when required information is absent, leading to incomplete or inaccurate outputs. Additionally, even with relevant information retrieved, the models may…

stp2y0 CommentsAI

This week has been filled with developments, including exciting new AI research that I’ll be discussing in my usual end-of-month write-ups.Additionally, I am excited to announce the release of my new book, Machine Learning Q and AI, published by No Starch Press.If you’ve been searching for a resource following an introductory machine learning course, this might be the one. I’m covering 30 concepts that were slightly out of scope for the previous books and courses I’ve taught, and I’ve compiled them here in a concise question-and-answer format (including exercises).I believe it will also serve as a useful companion for preparing…

One of the new ad formats Google announced today will allow brands to link short-form videos they made—or ones they hired creators to film—to their advertisements in Google’s search engine. AI-generated text summaries of the clips will be included below. “I’ve got three Gen Z-ers at home, and watching them shop, it’s very video-based,” said Madrigal.Google also launched a tool that allows companies to create entirely new, AI-generated product images based on photos from earlier marketing campaigns and pictures that represent their brand identity. For example, a home goods brand could upload a picture of one of its candles and…

The Shift from Models to Compound AI Systems

stp2y0 CommentsAIai routers, compound ai systems, dspy, frugalgpt

AI caught everyone’s attention in 2023 with Large Language Models (LLMs) that can be instructed to perform general tasks, such as translation or coding, just by prompting. This naturally led to an intense focus on models as the primary ingredient in AI application development, with everyone wondering what capabilities new LLMs will bring. As more developers begin to build using LLMs, however, we believe that this focus is rapidly changing: state-of-the-art AI results are increasingly obtained by compound systems with multiple components, not just monolithic models. For example, Google’s AlphaCode 2 set state-of-the-art results in programming through a carefully engineered…

Meta’s answer to GPT-4o? Meet Chameleon

stp2y0 CommentsAI

In the wake of OpenAI's recent announcement of GPT-4o, a new model that processes and generates text, audio, and images in real-time, it's clear that the race for multimodal AI is heating up. Not to be outdone, researchers at Meta AI (FAIR) have just released a fascinating new paper introducing Chameleon, a family of early-fusion foundation models that also seamlessly blend language and vision. In this post, we'll do a deep dive into the Chameleon paper, exploring how it pushes the boundaries of multimodal AI in different but equally exciting ways compared to GPT-4o. We’ll also speculate a bit on…
