Openttd signals explained5/24/2023 ![]() □♂️ The hard and expensive part of the above one-sentence explanation - the part that we’ve only recently hit on how to do using massive amounts of electricity and leading-edge computer chips - is hidden deep inside the word related. Or, you can write a computer program that uses rules and lookup tables, like a certain famous chatbot from the 60s that I’m sick of hearing about. Now, there are plenty of ways to turn one collection of symbols into another, related collection of symbols - you don’t even need computers to do this. Here are some examples of structured collections of symbols: ⭐️ But if you don’t have time to read all that, here’s a one-sentence explanation of a generative AI model: a generative model is a function that can take a structured collection of symbols as input and produce a related structured collection of symbols as output. The Hall Monitors Are Winning the AI Wars, Part 1: ChatGPT What Does It Mean to “Create” Something With Generative AI? If you want to know more about how generative ML models work and you have some time, read the following pieces:ĪI content generation series: Part 1, Part 2, Part 4 This family also includes Stable Diffusion and all the other prompt-driven, text-to-whatever models that are daily doing fresh miracles on everyone’s feeds right now. So what follows is my effort to help others get closer to the target in their thinking and writing about this new category of technology.Īt the heart of ChatGPT is a large language model (LLM) that belongs to the family of generative machine learning models. That said, I’m certainly far enough along that I can help others who are a few steps behind. (Speaking of, if you run a shop that sells dedicated ML workstations and would like to publicly sponsor this newsletter by sending me one, do get in touch.) Like everyone else, including active researchers in machine learning, I’m still on my own journey with getting my head around it at multiple levels. To be clear, I do not know everything I’d like to know about this topic. To put it another way, there are some can-opener problems manifesting in the ChatGPT conversation, and lowering the quality of The Discourse. Rather, what I mean is that they’re not working with a practical, productive understanding of what the bot’s main parts are and how they fit together. And by “unhelpful ways,” I don’t just mean that they’re anthropomorphizing (though they are doing that). In articles and podcasts, people are talking about this chatbot in unhelpful ways. Trains should now use all platforms, as the path signal will now allow trains to pass.The story so far: Most of the discussion of ChatGPT I’m seeing from even very smart, tech-savvy people is just not good. Then build a regular signal behind each platform. Try lengthening the area occupied by one tile, and extending each rail platform by adding a single tile of rail at the back. Your station design cannot guarantee that trains will not share a path after they leave, so the game will only allow a single train in at a time. As such, only one train will ever enter this block at the same time. We can thus say that your station is signalled as a single block, and has a single point of entry as well as exit within this block. Both trains will start at the same time, and crash into eachother! Now a rush of passengers suddenly appears, fully loading both trains. Imagine what happens if there are few passengers waiting, and two trains are let into the station. If the path a train is trying to take within its block is currently fully unoccupied, the signal will let the train through. Path signals will thus take into account where trains currently are. ![]() Path signals (the type in front of your station) have an exception: they will allow more trains in as long as the incoming train does not share a path with any trains currently within its block. Signals divide your rail into what's commonly known as signal blocks.Īll signals will forbid a train from entering a block if it is already occupied. In order to make your trains use your empty platforms on this station, it may be instructive to you to read more about how signals work in depth.
