RAG and Vector Database

대규모 언어모델(LLM)은 자연어 처리 분야에서 혁신적인 성과를 보여주고 있으며, 다양한 응용 서비스의 핵심 기술로 자리잡고 있다. 하지만 단독으로 사용할 경우 최신 지식 반영의 한계와 잘못된 정보를 생성하는 문제가 발생한다. 이를 해결하기 위한 방법으로 RAG(Retrieval-Augmented Generation)가 주목받고 있는데, 이는 사용자의 질문과 관련된 문서를 벡터 데이터베이스에서 검색하여 LLM의 입력에 결합함으로써 더 정확하고 신뢰성 있는 결과를 제공한다. 최근에는 단순 검색을 넘어, 스스로 도구를 활용하고 단계적으로 문제를 해결하는 Agentic RAG 개념도 등장하여 더욱 지능적인 시스템 구현이 가능해지고 있다. 이러한 기술들을 이해하기 위해서는 벡터 데이터베이스의 구조와 대량의 데이터를 효율적으로 다루는 인덱싱 기법이 핵심이다. 본 강의에서는 LLM의 기본 개념을 출발점으로 하여, RAG 및 Agentic RAG의 구조와 응용 사례를 살펴보고, 이를 뒷받침하는 벡터 데이터베이스와 인덱싱 기법의 원리를 설명한다.

Engineering for Intelligent Robotics

For robot manipulators to move out of industrial settings and into human environments, they will need physical intelligence for their interactions with the environment and humans and they will also need the dexterous capabilities of the human hand. This raises many unsolved problems, from designing the mechanisms and actuator technologies for such dexterous manipulators to their fine motor control with force and tactile sensing capabilities. These problems are interlinked: the mechanism for a manipulator is interdependent with its control which is interdependent with its sensing capabilities. This talk will present my past and recent work towards solving these problems.

Making Discoveries for Humanity and Society with Data Science

Data science is an interdisciplinary field of study that extracts knowledge and insight from diverse forms of data through the use of scientific methods, algorithms, and systems. In particular, data science based on mathematical modeling and artificial intelligence (AI) has become critical for effectively handling astronomically growing data in various fields.

In this talk, I will introduce two research themes—poverty mapping and fake news detection—that address global issues and have a social impact. These research themes are examples of computational social science.

I will also talk about life as a data scientist, based on my experiences collaborating with world-class scientists at Facebook, AT&T Research, and Max Planck Institute, as well as NGOs like the United Nations Pulse Lab and the World Customs Organization.

How to Manage Societies Better than Optimal?

Given the ongoing digital revolution and our present-day sustainability challenges, the ways cities and societies are operated are currently being reinvented. Societies are complex systems. This has important implications for how a society should be managed: Not like a company, and also not like a machine! I will illustrate our insights by means of pattern formation and self-organisation phenomena in social systems as well as applications to self-governance and self-control. Based on this, I will argue that the requirement of organizing societies in a more resilient way implies the need for more decentralized solutions based on digitally assisted self-organization – a concept, which is also compatible with sustainability requirements and greater participation. I will further discuss, how collective intelligence and co-creation can be supported in ways that promote favourable systemic outcomes – outcomes that are better than optimal, i.e. better than when optimization is applied. As an application example, I will present a field study on participatory budgeting, which has been recently carried out in Aarau, Switzerland. Specifically, I will show, how voting rules can be improved to promote individual and systemic benefits, such as inclusion and fairness.

Human Mobility Science

Human Mobility Modeling enables the understanding and characterization of time-variant movement and place visitation of individuals (or groups) in the real world. This knowledge is critical for domains like transportation planning, epidemic modeling, and energy use forecasting. Traditionally, simplistic statistical models such as a random walk or power law distribution were used to model these mobility patterns; however, it was determined that real-world mobility patterns are more complex and, therefore, require data-informed approaches for an accurate depiction. This talk will focus on the art and science of human mobility modeling with an emphasis on the use of Foundation Geoint data (demographics, points of interest, building footprint, etc.), behavior-driven movement-based patterns life generation, design and construction of data-informed human mobility model (HumoNet), spatio-temporal mobility interventions, and approaches to accurately benchmark mobility data to evaluate the presence of real-world mobility kinematics. The talk will conclude with the characterization of human mobility patterns from real-world scenarios, including disaster mitigation and cyber security attacks on critical infrastructure systems.

Frontiers of Collective Intelligence

In today’s world, complex systems capable of solving problems under significant pressure are omnipresent, including social networks, cities, and the Internet. The advent of Artificial Intelligence (AI) has added a new dimension to these systems, igniting debates about its deployment and long-term societal impacts. This seminar diverges from the conventional AI discourse, spotlighting an alternative form of experimental intelligence: Collective Intelligence. Collective Intelligence, which has evolved alongside the Internet, is distinguished by the collective capacity to address challenges and make decisions in ways that surpass the capabilities of individual members. In this seminar, I will share insights from several pivotal situations I have encountered, which illustrate the application of Collective Intelligence. In this seminar, we will explore the versatile applications of Collective Intelligence, including locating hidden entities across vast geographies, coordinating global searches for missing individuals, reassembling critically important shredded documents, and directing human actors in real-time via the Internet. By examining both the untapped potential and the inherent challenges of Collective Intelligence, the seminar aims to foster a dialogue on how the lessons learned from these experiences can inform the future development and strategic deployment of Artificial Intelligence.

Generative AI meets Vector databases and RAG techniques

In numerous industrial sectors, significant efforts are underway to enhance efficiency and automate operations utilizing generative AI models such as ChatGPT. Despite their potential, these technologies encounter three primary challenges: hallucination, data recency, and high cost. In response, the Retrieval-Augmented Generation (RAG) technique has emerged as a promising solution, receiving considerable attention for its potential to mitigate these challenges. RAG addresses hallucination and data recency problems by enabling generative AI models to access and retrieve relevant facts from databases, subsequently generating responses based on this retrieved data. Vector databases, which are extensively employed for this purpose, embed diverse data types, including documents, images, and videos, into multi-dimensional vectors. To effectively counter the curse of dimensionality, vector databases typically employ graph-based indexes. RAG has been enhanced with variations like iterative RAG and plan RAG to tackle more complex challenges. Iterative RAG repeatedly executes the retrieval and generation cycle, while plan RAG strategizes to solve intricate corporate decision-making problems prior to retrieval and generation. In this talk, I will introduce these innovative methodologies about vector databases and RAG techniques.

Under the Ground, Over the Oceans, and through the Space: Exploring the World with Imaging Beyond the Visible Spectrum.

Hyperspectral cameras are specialized devices that capture hundreds of images from across the electromagnetic spectrum. This comprehensive collection allows for the identification and labeling of each pixel based on its material composition, be it grass, water, gold, cotton, and more. The wealth of information provided by hyperspectral imaging has far-reaching applications in diverse fields such as agriculture, astronomy, medical imaging, and defense. In this presentation, I will introduce our research which ventures beyond the limitations of the visible spectrum using radar and hyperspectral images, seeing under the ground, over the oceans and through space. Additionally, I will outline our current research on deep denoising networks for hyperspectral imaging (HSI), introduce the current trends, discuss the future of HSI with the current paradigm shifts in the imaging pipeline, and touch upon the low-cost programmable cameras that put the HSI capability to our cell-phones.
