Using VLMs to Navigate the Sea of Data

At SEA.AI, we aim to make ocean navigation safer by enhancing situational awareness with AI. To develop our technology, we process huge amounts of maritime video from onboard cameras. In this talk, we’ll show how we use Vision-Language Models (VLMs) to streamline our data workflows; from semantic search using embeddings to automatically surfacing rare or high-interest events like whale spouts or drifting containers. The goal: smarter data curation with minimal manual effort.

SAMWISE: Infusing Wisdom in SAM2 for Text-Driven Video Segmentation

Referring Video Object Segmentation (RVOS) involves segmenting objects in video based on natural language descriptions. SAMWISE builds on Segment Anything 2 (SAM2) to support RVOS in streaming settings, without fine-tuning and without relying on external large Vision-Language Models. We introduce a novel adapter that injects temporal cues and multi-modal reasoning directly into the feature extraction process, enabling both language understanding and motion modeling. We also unveil a phenomenon we denote tracking bias, where SAM2 may persistently follow an object that only loosely matches the query, and propose a learnable module to mitigate it. SAMWISE achieves state-of-the-art performance across multiple benchmarks with less than 5M additional parameters.

Your Data Is Lying to You: How Semantic Search Helps You Find the Truth in Visual Datasets

High-performing models start with high-quality data—but finding noisy, mislabeled, or edge-case samples across massive datasets remains a significant bottleneck. In this session, we’ll explore a scalable approach to curating and refining large-scale visual datasets using semantic search powered by transformer-based embeddings. By leveraging similarity search and multimodal representation learning, you’ll learn to surface hidden patterns, detect inconsistencies, and uncover edge cases. We’ll also discuss how these techniques can be integrated into data lakes and large-scale pipelines to streamline model debugging, dataset optimization, and the development of more robust foundation models in computer vision. Join us to discover how semantic search reshapes how we build and refine AI systems.

About the Workshop

Visual AI is revolutionizing healthcare by enabling more accurate diagnoses, streamlining medical workflows, and uncovering valuable insights across various imaging modalities. Yet, building trustworthy AI in healthcare demands more than powerful models — it requires clean, curated data, strong visualizations, and human-in-the-loop understanding.

Join us for a free, 90-minute, hands-on workshop built for healthcare researchers, medical data scientists, and AI engineers working with real-world imaging data. Whether you're analyzing CT scans, radiology images, or multi-modal patient datasets, this session will equip you with the tools to design robust, transparent, and insight-driven computer vision pipelines — powered by FiftyOne, the open-source platform for Visual AI.

By the end of the workshop, you'll be able to:

• Load and organize complex medical datasets (e.g., ARCADE, DeepLesion) with FiftyOne.
• Explore medical imaging data using embeddings, patches, and metadata filters.
• Curate balanced datasets and fine-tune models using Ultralytics YOLOv8 for tasks like stenosis detection.
• Analyze segment CT scans using MedSAM2.
• Analyze results from VLMs and foundation models like MedGEMMA, NVIDIA VISTA, and NVIDIA CRADIO.
• Evaluate model predictions and uncover failure cases using real-world clinical examples.

Why Attend?

This healthcare edition of our "Getting Started with FiftyOne" workshop connects foundational tools with real-world impact. Through curated datasets and clinical use cases, you'll see how to harness Visual AI responsibly, building data-centric pipelines that promote accuracy, interpretability, and trust in medical AI systems.

Prerequisites

Basic knowledge of Python and computer vision is recommended. No prior experience in healthcare is required — just curiosity and a commitment to building meaningful AI.

All participants will receive access to workshop notebooks, code examples, and extended resources to continue their journey in healthcare AI.

Foundational capabilities and models for generalist agents for computers

As we move toward a future where language agents can operate software, browse the web, and automate tasks across digital environments, a pressing challenge emerges: how do we build foundational models that can act as generalist agents for computers? In this talk, we explore the design of such agents—ones that combine vision, language, and action to understand complex interfaces and carry out user-intent accurately.

We present OmniACT as a case study, a benchmark that grounds this vision by pairing natural language prompts with UI screenshots and executable scripts for both desktop and web environments. Through OmniACT, we examine the performance of today’s top language and multimodal models, highlight the limitations in current agent behavior, and discuss research directions needed to close the gap toward truly capable, general-purpose digital agents.

Implementing a Practical Vision-Based Android AI Agent

In this talk I will share with you practical details of designing and implementing Android AI agents, using deki.

From theory we will move to practice and the usage of these agents in
industry/production.

For end users - remote usage of Android phones or for automation of standard tasks. Such as:

• "Write my friend 'some_name' in WhatsApp that I'll be 15 minutes late"
• "Open Twitter in the browser and write a post about 'something'"
• "Read my latest notifications and say if there are any important ones"
• "Write a linkedin post about 'something'"

And for professionals - to enable agentic testing, a new type of test that only became possible because of the popularization of LLMs and AI agents that use them as a reasoning core.
