Wednesday is karaoke day. Every Wednesday we gather to sing. Come with a friend or alone, with or without a voice. The format is simple: show up, grab a microphone, and sing whatever you want. Or don't sing, just support others. As usual, the meeting place is Top Club. If you haven't been before, you can get to know the space at the same time. We're looking forward to seeing you this Wednesday. See you there! Trešdiena ir karaoke diena. Katru trešdienu mēs pulcējamies dziedāt. Nāc ar draugu vai viens, ar balsi vai bez. Formāts ir vienkāršs: nāc, paņem mikrofonu un dziedi, ko vien vēlies. Vai arī nedzied, vienkārši atbalsti citus. Kā parasti, tikšanās vieta ir Top klubs. Ja iepriekš neesi tur bijis, vari vienlaikus iepazīties ar vietu. Gaidīsim ciemos šajā trešdienā. Tiekamies tur!

## Riga Philosophy Discussion Meetup #4 Welcome to an open philosophy discussion for curious minds, thoughtful conversation, and respectful debate. This event is where people from different backgrounds gather to exchange ideas, challenge assumptions, and explore life’s bigger questions together. The purpose of this meetup is not to “win” arguments or prove others wrong, but to think deeply, listen carefully, and enjoy meaningful conversation. Whether you are new to philosophy or have studied it for years, everyone is welcome. **Topics may include:** * *Ethics and morality* * *Consciousness and free will* * *Meaning and purpose* * *Technology and society* * *Politics and human nature* * *Happiness and suffering* * *Logic, reason, and belief* * *Artificial intelligence and the future* * *Classic philosophical ideas and modern dilemmas* For our fourth meetup, we will begin by proposing several discussion topics. The group can then vote, and by majority we will explore whichever topic generates the most interest. Possible discussion topics: * *Are humans naturally good or selfish?* * *Can happiness be the highest goal?* * *Ethics of artificial intelligence* * *Is ignorance bliss?* * *Should emotions guide decisions?* The format will be informal, open, and conversational. Everyone is encouraged to participate, ask questions, and share perspectives respectfully. **Simply look for the table with the small Latvian flag on it outside.** (or inside if the weather is not so nice) *Note: The conversation and all discussion will solely be in English.*

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
