Compute dense vector representations for sentences and paragraphs using a Python framework that optimizes transformer models for semantic similarity.

Sentence Transformers (SBERT) maps variable-length text into fixed-size, high-dimensional vectors to enable high-speed semantic analysis. The framework fine-tunes architectures like BERT using Siamese and Triplet network structures: this ensures semantically similar inputs cluster together in vector space. This methodology powers critical NLP tasks: semantic search, clustering, and paraphrase detection. Standard models (like all-MiniLM-L6-v2) provide a 384-dimensional baseline for real-time applications, while larger variants (such as all-mpnet-base-v2) offer superior accuracy for complex information retrieval.

### [Teaching an LLM to Play Riftbound](https://ottawa.aitinkerers.org/talks/rsvp_CPcwK2QKRgg)

Samuel demonstrates a framework he built to teach AI agents to play Riftbound, the League of Legends-based trading card game. The system translates English card text and the current board state into legal actions, uses Gemma to choose moves in player-versus-bot or bot-versus-bot simulations, and is designed to generate training experience so a faster machine-learning policy can eventually select optimal plays without relying on slower LLM inference at the final decision stage.

### [Building an AI-Powered Learning Navigator: The Blueprint for Hyper-Personalized Education](https://ee.dream.page/talks/rsvp_PWHkDcFRZ8M)

AceRocket is an AI-powered learning navigator designed to help high school students master math with clarity, confidence, and consistency. Unlike traditional test prep which relies on static worksheets, long videos, or expensive tutoring — AceRocket provides a dynamic, personalized practice system driven by AI and real performance data. In my presentation, I will introduce: * What problem AceRocket solves: students feel lost, parents lack visibility, and traditional prep tools do not adapt to individual gaps. * How our Triple-A Learning Cycle (Active, Adaptive, AI-powered) guides students through daily personalized practice that adjusts in real time. * Early traction from local Eastside students, parents, and educators. * Our business model and our plan to scale from math exams into broader AI-driven learning guidance and workforce training. The talk will give the audience a clear understanding of AceRocket’s value, technology, and our roadmap toward becoming the "AI learning GPS" for millions of learners.

### [Differentiable Physics with Keep It Cool](https://chicago.aitinkerers.org/talks/rsvp_Vh_870bwof4)

Physics-based simulation is used to provide insight into many practical problems. At Keep it Cool, we use conservation of energy to model heat flow across the delivery cycle of temperature-sensitive packaging. However, uncertainties add considerable fog to the computational modeling process. Questions like "How exactly is this box packed?" or "Is this insulation really performing as well as advertised?" can cause issues. Luckily, a wealth of sensor data has been collected during transit of these temperature-sensitive packages, allowing us to connect the computational physics to real-world data. We can then use machine learning techniques to tune the physics model to match the sensor, and thus the real-world, behavior.

### [Processing lidar into datasets used in machine learning](https://fort-wayne.aitinkerers.org/talks/rsvp_UVcx_eG1pnw)

Lidar is a pulsed laser scan of the surface of the Earth. Billions of points contain accurate X,Y and Z coordinates. This dense dataset can be used to build digital elevation models, hill shaded images, slope angles and flow accumulation models. This talk will describe and show how the lidar point cloud is downloaded, processed and interpreted into a digital format that can be used in machine learning algorithms. The ultimate goal will be to combine the results of many machine learning models in LLM's to predict the nature and fabric of the sub surface.

### [Leveraging AI for Structural Safety in Mining Operations](https://bogota.aitinkerers.org/talks/rsvp_xwxTWYagvts)

The project "Anomalies Detection in Tunnels" focuses on detecting deformations and anomalies in mining tunnels to prevent structural collapses. It employs anomaly detection models applied to point clouds to analyze three-dimensional data captured during mining operations. The primary goal is to identify and assess deformations or irregularities in tunnel structures that could jeopardize the safety and stability of excavation operations. By utilizing advanced data analysis techniques and machine learning models, the project aims to provide accurate tools for monitoring and early intervention, thus preventing potential collapses and ensuring the integrity of mining operations.

### [MoodWeb - Connect with Others based on Emotions](https://sf.aitinkerers.org/talks/rsvp_ZuvgfAmwti4)

MoodWeb's slogan is 'see who likes you'. Originally an app against loneliness, MoodWeb now pivoted into the online dating industry. Log in and let the app pick up on how you are currently feeling - based on the way you hold your phone while typing (the exciting ML part). Get a corresponding colour (or gradient) bubble assigned to you. Filter based on radius (or location aka San Francisco or Berlin) who else is currently online and what they are currently feeling and send them anonymous chat requests for 15 minutes. Or join group chats with prompts and answer in realtime with strangers who are currently going through the same emotion as you are. Add your friends and family to see how they felt the last time they logged in and reach out to them - text messages get colour bubbles that indicate how you were feeling when you typed your message - based on the way you hold your phone while typing, not on the contents of your message.

### [How and why we use AI for creating serialized apparel](https://portland.aitinkerers.org/talks/rsvp_UfkXRFqKpd8)

Spot Vision uses machine learning to encode a digital record into graphic designs by introducing slight variations to the designs. These variations allows us to serialize the millions of items so that each is slightly different but still fitting a shared design intent. Designs can be read or authenticated by visually scanning. We will be demonstrating examples of serialized apparel covering a broad artistic range and talk about how AI drives optimization of encoding schemes and robust decoding from curved, obscured, and wrinkled surfaces.

### [Automating building, deployment and maintenance of AI with AI agents](https://london.aitinkerers.org/talks/rsvp_pfh4cKzrGok)

Nowadays, everyone wants to integrate AI into their products or workflows, but building and maintaining AI models remains challenging, especially for non-experts. Weco uses AI agents to help developers implement AI features without dealing with low-level details like prompt engineering, model selection, output structuring, or writing machine learning code. Users submit task descriptions in natural language, and our system provides an API endpoint for the requested AI feature.

### [Local LLM Social Media Filter](https://chicago.aitinkerers.org/talks/rsvp_ZKE5CrbzojE)

AI Filter is a Chrome extension that uses a local language model to filter your social media feeds (currently, only Twitter / X) according to your instructions. For instance, you can say: Hide all tweets, except for tweets about machine learning (ML), artificial intelligence (AI) and large language models (LLMs). or: By default, show all tweets Do not show any tweets related to cryptocurrencies, blockchain, Bitcoin, Ethereum or related projects. AI Filter will follow your instructions, hiding the appropriate tweets in the background as you browse Twitter.
