The speed with which intelligent systems can react to an action depends on how soon it can be recognized. The ability to recognize ongoing actions is critical in many applications, for example, spotting criminal activity. It is challenging, since decisions have to be made based on partial videos of temporally incomplete action executions. In this paper, we propose a novel discriminative multi-s...

A classic PCFG is a generative parsing model, a model of the joint probability P (x, y) of input and output. In this lecture, I will first review the distinction between generative and discriminative models (§1) and introduce the widely used log-linear models (§2). I will then discuss three different ways in which these models are used in current parsing systems: local discriminative models (§3...

Training discriminative classifiers for a large number of classes is a challenging problem due to increased ambiguities between classes. In order to better handle the ambiguities and to improve the scalability of classifiers to larger number of categories, we learn pairwise dissimilarity profiles (functions of spatial location) between categories and adapt them into nearest neighbor classificat...

This study addressed the neural mediation of discriminative avoidance learning, wherein rabbits step in a wheel apparatus in response to an acoustic conditional stimulus, the CS+, to avoid a foot shock, and they learn to ignore a different stimulus, the CS-, not followed by foot shock. Previously, muscimol-induced inactivation of the amygdala in the first session of training prevented learning ...

OBJECTIVE To evaluate whether patients suffering from whiplash-associated disorders have impaired shoulder proprioception and whether the acuity of shoulder proprioception is reflected in the patients' symptoms and self-rated function. DESIGN A comparative group design, including a correlation design for the patient group. SUBJECTS Patients with chronic whiplash-associated disorders (n=37) ...

INTRODUCTION The objective of this study was to determine the ability of various parameters commonly used for the diagnosis of acute meningitis to differentiate between bacterial and viral meningitis, in adult patients with a negative direct cerebrospinal fluid (CSF) examination. METHODS This was a prospective study, started in 1997, including all patients admitted to the emergency unit with ...

abstract the effect of weight and force is one of the most important factors to organize and perform reaction time (rt) tasks. the elderly are involved in this variable when they gain weight. the present study was designed to examine the effect of limb weight gain on premotor and motor components of simple and discriminative reaction time in young and elderly men. subjects (16 young and 16 elde...

The purpose of this study was to determine the relevance of standardized uptake value (SUV) on [F]fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT), focusing on tumor and bone marrow, to disease outcomes based on progression-free survival (PFS) and overall survival (OS) in patients with diffuse large B-cell lymphoma (DLBCL) receiving rituximab-containing chemoth...

We present a discriminative model for Japanese zero anaphora resolution that simultaneously determines an appropriate case frame for a given predicate and its predicate-argument structure. Our model is based on a log linear framework, and exploits lexical features obtained from a large raw corpus, as well as non-lexical features obtained from a relatively small annotated corpus. We report the r...
