Summary

This article looks back at a year of tremendous advances in AI in 2022, including the emergence of generative AI, language models, vision transformers, and AI-powered coding tools. These advances have enabled the creation of synthetic images, text, and code and raised questions about the future of creativity. The article also looks ahead to the potential of general-purpose models and the regulatory implications of their development.

Q&As

What is generative AI and how is it different to supervised learning?
Generative AI is a tool built on top of supervised learning that enables AI to generate complex and compelling outputs such as images or paragraphs of text. Supervised learning is trained to generate short labels (such as spam/not-spam) or a sequence of labels (such as a transcript of audio).

How did image-generation models become a popular feature in software applications?
Image-generation models became a popular feature in software applications because they are user-friendly, produce highly entertaining output, and have open APIs and models. Companies such as Adobe, Getty Images, and Shutterstock integrated image-generation models into their own products and services.

What is the purpose of language models and how have researchers worked to make their output more trustworthy?
The purpose of language models is to generate plausible text. Researchers have worked to make their output more trustworthy and less inflammatory by introducing models that retrieve passages from the MassiveText dataset and integrate them into its output, introducing a suite of modules to fact-check a language model’s answers, and fine-tuning models to minimize untruthful, biased, or harmful output.

What is the potential of multi-task models to perform a variety of tasks?
Multi-task models have the potential to learn over 600 diverse tasks, such as playing Atari games, stacking blocks using a robot arm, generating image captions, and so on. They can also learn from a wide variety of datasets simultaneously, from text and images to actions generated by reinforcement learning agents.

What is the European Union's proposed AI Act and why has it been criticized?
The European Union's proposed AI Act would require users of general-purpose AI systems to register with the authorities, assess their systems for potential misuse, and conduct regular audits. It defines general-purpose systems as those that “perform generally applicable functions such as image/speech recognition, audio/video generation, pattern-detection, question-answering, translation, etc.,” and are able to “have multiple intended and unintended purposes.” It has been criticized as being too broad.

AI Comments

👍 This article provides a comprehensive overview of the advances and breakthroughs that AI has made in the past year. It is informative and provides a great insight into the exciting developments that are taking place in the AI field.

👎 There is a lack of detail in the article about the potential downsides and ethical implications of AI, such as its potential to perpetuate biases and its lack of trustworthiness.

AI Discussion

Me: It's an overview of the top AI stories of 2022. It discusses the advances in AI this year, such as generative AI, vision transformers, language models, and multi-task models.

Friend: Wow, that's amazing! What implications does this have?

Me: Well, AI has the potential to revolutionize computer-aided creativity, open up new possibilities for software development, and make language models more trustworthy and less biased. On the other hand, it's still early days for many of these applications and there are still legal and ethical issues to be worked through. It's also important to note that AI-generated outputs can be easily misinterpreted or misused, so there needs to be more regulation in this area.
