A VQ (vector quantization)-distortion-based speaker recognition method and discrete/continuous ergodic HMM (hidden Markov model)-based ones are compared, especially from the viewpoint of robustness against utterance variations. It is shown that a continuous far superior to discrete HMM. also information on transitions between different states ineffective for text-independent recognition. Therefore, identification rates using strongly correlated with total number mixtures irrespective states....
Recently, a series of studies demonstrated false belief understanding in young children through completely nonverbal measures. These have revealed that younger than 3 years age, who consistently fail the standard verbal test, can anticipate others' actions based on their attributed beliefs. The current study examined whether with autism spectrum disorder (ASD), are known to difficulties may also show such action anticipation test. We presented video stimuli an actor watching object being...
Methods that create models to specify both speaker and phonetic information accurately by using only a small amount of training data for each are investigated. For text-dependent recognition method, in which arbitrary key texts prompted from the recognizer, speaker-specific phoneme necessary identify text recognize speaker. Two methods making discussed: phoneme-adaptation phoneme-independent model speaker-adaptation universal models. The authors also investigate supplementing these adding...
Gaussian Processes (GPs) are Bayesian nonparametric models that becoming more and popular for their superior capabilities to capture highly nonlinear data relationships in various tasks, such as dimensionality reduction, time series analysis, novelty detection, well classical regression classification tasks. In this paper, we investigate the feasibility applicability of GP music genre emotion estimation. These two main tasks information retrieval (MIR) field. So far, support vector machine...
It has been repeatedly shown that when asked to identify a protagonist's false belief on the basis of his statement, English-speaking 3-year-olds dismiss statement and fail attribute him belief. In present studies, we tested 3-year-old Japanese children in similar task, using statements accompanied by grammaticalized particles speaker (un)certainty, as everyday utterances. The were directly compared with same-aged German children, whose native language does not have epistemic concepts....
A hearer's perception of an utterance as sarcastic depends on integration the heard statement, discourse context, and prosody utterance, well evaluation incongruity among these aspects. The effect in sarcasm comprehension is evident everyday conversation, but little known about its underlying mechanism or neural substrates. To elucidate underpinnings auditory modality, we conducted a functional MRI experiment with 21 adult participants. participants were provided short vignette which child...
Public transport, or mass transit, is believed to bring several benefits, including energy efficiency, air quality and an economy of scale with respect total public transport costs. An important factor in providing the cost-efficient timely service, ability do resource planning optimization based on up-to-date data passenger counts flows. In this work we give a novel approach counting number passengers bus WiFi signatures from any mobile devices carried onto vehicle. This provides traffic...
This paper compares a VQ (vector quantization)-distortion-based speaker recognition method and discrete/continuous ergodic HMM (hidden Markov model)-based ones, especially from the viewpoint of robustness against utterance variations. The authors show that continuous is as robust VQ-distortion when enough data available far superior to discrete HMM. They also information on transitions between different states ineffective for text-independent recognition. Therefore, rates using are strongly...
Real-time urban climate monitoring provides useful information that can be utilized to help management personnel monitor and adapt their precautionary measures extreme events, including heatwaves. Fortunately, recently created social media platforms, such as Twitter, furnish real-time high-resolution spatial may for condition estimation. The objective of this paper was utilize geotagged tweets (participatory sensing data) temperature analysis. We first detected related heat (heat-tweets)....
One significant problem for spoken language systems is how to cope with users' out-of-domain (OOD) utterances which cannot be handled by the back-end application system.In this paper, we propose a novel OOD detection framework, makes use of classification confidence scores multiple topics and applies linear discriminant model perform in-domain verification.The verification trained using combination deleted interpolation data minimum-classification-error training, does not require actual...
The authors describe a VQ (vector-quantization)-based text-independent speaker recognition method which is robust against utterance variations. Three techniques are introduced to cope with temporal and text-dependent spectral First, either an ergodic hidden Markov model or voiced/unvoiced decision used classify input speech into broad phonetic classes. Second, new distance measure, the distortion-intersection measure (DIM), for calculating distortion of compared speaker-independent...
We develop new algorithms for spatial field reconstruction, exceedance level estimation and classification in heterogeneous (mixed analog & digital sensors) Wireless Sensor Networks (WSNs). consider physical phenomena which are observed by a WSN, meaning that it consists partially of sparsely deployed high-quality sensors low-quality sensors. The transmit their (continuous) noisy observations to the Fusion Centre (FC), while first perform simple thresholding operation then binary values over...
Abstract Developmental research suggests that young children tend to value dominant individuals over subordinates. This research, however, has nearly exclusively been carried out in Western cultures, and cross-cultural among adults revealed cultural differences the valuing of dominance. In particular, it seems Japanese culture, relative many values dominance less. We conducted two experiments test whether this difference would be observed preschoolers. Experiment 1, preschoolers France Japan...
Significant improvement in progression-free survival (PFS; primary end point) was reported the phase 3 RELAY study with ramucirumab (RAM) plus erlotinib (ERL) versus placebo (PL) untreated EGFR-mutated NSCLC (hazard ratio [HR] = 0.59, 95% confidence interval [CI]: 0.46-0.76, p < 0.0001), including Japanese subset. We report updated PFS and final overall (OS) for Patients (no central nervous system metastases) were randomized 1:1 (stratification included EGFR leucine to arginine substitution...
