Evolution of AI Capabilities
Over the past decade, the field of AI has witnessed substantial advancements due to the success of deep learning methods. The progress in AI capabilities has outpaced expectations, with AIs now excelling in various tasks, making it challenging to find tasks they can't master. This progress has largely been driven by scaling up simple algorithms rather than through a principled understanding of deep learning.
Revolution in Image Recognition
Image recognition, a longstanding focus in AI, has seen remarkable advancements. AI models now surpass human performance in tasks like handwriting and image recognition. Graphs illustrate the rapid improvement in AI capabilities, with image recognition reaching human levels in under five years.
Advancements in AI Image Generation
Starting from simple and blurry images, AI's image generation capabilities have dramatically enhanced, particularly with the introduction of GANs in 2014. Progress accelerated in recent years, with AI systems generating complex and creative visuals, responding to language prompts and producing increasingly detailed and realistic images.
Impact of Scaling Compute in AI Development
The accelerated progress in AI is attributed to scaling compute and data used during training. Larger compute models outperform smaller ones in tasks such as image portrayal, evident in the evolution of AI-generated images, from initial nonsensical outputs to detailed and lifelike representations.
The field of AI has undergone a revolution over the last decade, driven by the success of deep learning techniques. This post aims to convey three ideas using a series of illustrative examples:
There have been huge jumps in the capabilities of AIs over the last decade, to the point where it’s becoming hard to specify tasks that AIs can’t do.
This progress has been primarily driven by scaling up a handful of relatively simple algorithms (rather than by developing a more principled or scientific understanding of deep learning).
Very few people predicted that progress would be anywhere near this fast; but many of those who did also predict that we might face existential risk from AGI in the coming decades.
I’ll focus on four domains: vision, games, language-based tasks, and science. The first two have more limited real-world applications, but provide particularly graphic and intuitive examples of the pace of progress.
