Complex objects are usually with multiple modal features. In multi-modal learning, modalities closely related to the target tasks are known as strong modalities. While collecting strong modalities of all instances is often expensive, and current multi-modal learning techniques hardly take the strong modal feature extraction expenses into consideration. On the other hand, active learning is prop...

In environments with information symmetry, uncertain or ambiguous data associations can lead to a multi-modal hypothesis on the robot’s state. Thus, a planner cannot simply base actions on the most-likely state. We propose an algorithm that uses a Receding Horizon Planning approach to plan actions that sequentially disambiguate a multi-modal belief to a uni-modal Gaussian and achieve tight loca...

high speed trains are an indispensable part of rapid transportation systems in many countries. as the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Despite half a century of fuzzy sets and fuzzy logic progress, as fuzzy sets address complex and uncertain information through the lens of human knowledge and subjectivity, more progress is needed in the semantics of fuzzy sets and in exploring the multi-modal aspect of fuzzy logic due to the different cognitive, emotional and behavioral angles of assessing truth. We lay here the foundations of...

In this paper we present a multi-modal web interface for autonomous mobile robots. The purpose of this interface is twofold. It serves as a tool for task supervision for the researcher and task specification for the end-user. The applications envisaged are typical service scenarios like remote inspection, transportation tasks or tour guiding. Instead of post-processing a huge amount of data gat...

This paper presents an overview of the spoken and multimodal dialog Portuguese corpora collected in the context of the FASiL (Flexible and Adaptive Spoken Language and Multi-Modal Interfaces) project. The project developed a Virtual Personal Assistant application in the Personal Information Management domain, exploiting the state-of-theart of speech and multi-modal technology. The FASiL corpora...

This study proposes a bi-level optimization model for the transit frequency setting problem in bi-modal networks. The objective of upper-level is to obtain solution set bus line frequencies that provide minimum total travel cost car and users. Differential Evolution (DE) algorithm employed determine optimal headways given route structure. lower-level congested multi-modal user equilibrium assig...

Multi-modal virtual environments succeed better, than single-channel technologies, in creating the 'sense of presence'. We hypothesize that the underlying cognitive mechanism is related to a faster mental processing of multimodal events. Comparing reaction time in uni-modal, bimodal and tri-modal events, we show that the processing speed is: uni-modal > bi-modal > tri-modal. Given this advantag...
