A blog about computer vision, robotics, and artificial intelligence.
(by Li Yang Ku) In this post I will start from the policy equation used in reinforcement learning (RL) to logically show that the most reasonable outcome is to believe that humans have souls. This conclusion may seem to be a bit out of the blue, but I have yet to find logical flaws. The [ ]
(by Li Yang Ku) Recently I ve been on leave to take care of my little one born earlier this year, which leaves me with some time to listen to quite a few audiobooks. This post is about some of the thoughts I gathered after all the listening while trying to grasp the meaning of my [ ]
(By Li Yang Ku) In my last post I talked about how generative diffusion models (such as DALLE, Imagen, and Stable Diffusion) work. I also mentioned that I would talk about specific models and tools like Stable Diffusion and ControlNet. I admit that this second post took a bit longer than I expected, mostly due to my laziness [ ]
(By Li Yang Ku) It s interesting times to be in the field of Computer Vision. In the past I judge the quality of a Computer Vision publication based on it s accuracy on benchmarks and the number of citations. Now I also consider how popular it is on Reddit and Youtube. With all the Computer Vision [ ]
(By Li Yang Ku) I worked at Vicarious, a robotics AI startup, from mid 2018 till it was acquired by Alphabet in 2022. Vicarious was a startup founded before the deep learning boom and it had been approaching AI through a more neuroscience based graphical model path. Nowadays it is definitely rare for AI startups [ ]
(By Li Yang Ku) In the past I ve always avoided to make comments about consciousness. My view was that due to consciousness being internal to ourselves it is extremely difficult if not impossible to evaluate scientifically. Also, why talk about consciousness when we couldn t even understand intelligence? However, some recent readings have changed my view [ ]
(By Li Yang Ku) 2023 August Update: Install file for Mac now available on my personal site. Visual Loop Machine is my new side project since the Rap Machine I made that completes rap sentences. It is a tool that plays visual loops generated by StyleGAN2 along music in real-time. One of the reasons I [ ]
(By Li Yang Ku) For many researchers in the field of Computer Vision, coming up with the object representation is a lifetime goal. An object representation is the result of mapping an Image to a feature space such that an agent can recognize or interact with these object. The field came a long way from [ ]
(By Li Yang Ku) I was at the Bay Area Robotics Symposium (BARS) at Stanford in person last week. It s nice to see real person even though there is a mask mandate (which could be a good thing since the audience won t be biased by the speaker s look.) Faculty talks can be found in the [ ]
(By Li Yang Ku) In my previous post I talked about this web app I made that can generate rap lyrics using the transformer network. Transformer is currently the most popular approach for natural language related tasks (I am counting OpenAI s GPT-3 as a transformer extension.) In this post I am going to talk about [ ]
