Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Semantic Virtual Environments with Adaptive Multimodal Interfaces

Daniel Thalmann, Frédéric Vexo

We present a system for real-time configuration of multimodal interfaces to Virtual Environments (VE). The flexibility of our tool is supported by a semantics-based representation of VEs. Semantic descriptors are used to define interaction devices and virt ...

Browsing the environment with the SNAP&TELL wearable computer system

Ali H. Sayed

This paper provides an overview of a multi-modal wearable computer system, SNAP&TELL. The system performs real-time gesture tracking, combined with audio-based control commands, in order to recognize objects in an environment, including outdoor landmarks. ...

Tracking and User Interface for Mixed Reality

Touradj Ebrahimi, Yousri Abdeljaoued

This chapter introduces the field of Mixed Reality that merges the real and virtual worlds seamlessly. To develop a Mixed Reality system, two fundamental problems should be addressed: tracking and user interface. Tracking in Mixed Reality is defined as the ...

Performance Driven Reliable Link Design for Networks on Chips

Giovanni De Micheli, Srinivasan Murali

With decreasing feature size of transistors, the interconnect wire delay is becoming a major bottleneck in current Systems on Chips (SoCs). Another effect of shrinking feature size is that the wires are becoming unrealable as they are increasingly suscepti ...

Agile preference models based on soft constraints

Boi Faltings, Pearl Pu Faltings, Jiyong Zhang

An accurate model of the user's preferences is a crucial element of most decision support systems. It is often assumed that users have a well-defined and stable set of preferences that can be elicited through a set of questions. However, recent research ha ...

Enforcing email addresses privacy using tokens

Serge Vaudenay, Roman Schlegel

We propose a system which allows users to monitor how their email addresses are used and how they spread over the Internet. This protects the privacy of the user and can reduce the spam phenomenon. Our solution does not require changes to the email infrast ...

Designing Example-critiquing Interaction

Boi Faltings, Pearl Pu Faltings, Paolo Viappiani

In many practical scenarios, users are faced with the problem of choosing the most preferred outcome from a large set of possibilities. As people are unable to sift through them manually, decisions support systems are often used to automatically find the o ...

Towards an intelligent mobile travel assistant

Boi Faltings, Pearl Pu Faltings

Travel has many situations where context-aware computing can bring important benefits. In this paper, we describe an approach for integrating context-aware computing to a mobile travel assistant. Travel plans, generated using reality [2], are enriched with ...

Bayesian Networks Based Signal Fusion for User Goal Identification in Human-Robot Dialogues

In this paper, we introduce probabilistic framework for robust identification of the user goals in human-robot speech-based interaction. The concept of Bayesian networks is used for interpreting multimodal signals in the spoken dialogue between a tour-guid ...

A Dialogue-based Grounding mechanism and new Service Description Features for adapting Semantic (Web) Services to Personal Assistants

Martin Rajman, David Portabella Clotet

We delegate increasingly sophisticated and complex tasks to computer programs, and we require them to act autonomously on our behalf in distributed environments (eg the web, the grid). Personal Assistants (PA) are computer programs that can be thought as a ...
