In this paper, we investigate the problem of sparse online linear classification in changing environments. We first analyze tracking performance standard classifiers, which use gradient descent for minimizing regularized hinge loss. The derived shifting bounds highlight importance choosing appropriate step sizes presence concept drifts. Notably, show that a better adaptability to drifts can be achieved using constant rather than state-of-the-art decreasing sizes. Based on these observations,...
In the RECO study, we investigated impact of operator's choice stent retriever size on patients with internal carotid artery (ICA) occlusion.
To determine whether items of the Chinese version Montreal Cognitive Assessment Basic (MoCA-BC) could discriminate among cognitively normal controls (NC), and those with mild cognitive impairment (MCI), Alzheimer's disease (AD), moderate-severe as well their sensitivity specificity.MCI (n = 456), AD 502) 102) patients were recruited from memory clinic, Huashan Hospital, Shanghai, China. NC 329) health checkup outpatients. Five MoCA-BC item scores collected in interviews.The orientation test...
Abstract Background: The clinical use of tirofiban remains controversial for patients with acute ischemic stroke (AIS), we aimed to conduct a meta- analysis cohort studies assess the efficacy and safety AIS patients. Methods: All apparently unconfounded randomized controlled trials (RCTs) case-controlled studies, or without blinding, in individuals will be included this review. We literature search 2 databases Pubmed Embase, using indexing terms related cerebral infarctions include articles...
Most existing multilabel classification methods are batch learning methods, which may suffer from expensive retraining costs when dealing with new incoming data. In order to overcome the drawbacks of learning, we develop a family online algorithms, can update model instantly and efficiently, make timely prediction data arrive. Our algorithms all take closed-form update, is obtained by solving constrained optimization problem in each round learning. Label correlation explicitly modeled our...
Abstract The RECO is a novel endovascular treatment (EVT) device that adjusts the distance between two mesh segments to axially hold thrombus. We organized this postmarket study assess safety and performance of in acute ischaemic stroke (AIS) patients with large vessel occlusion (LVO). This was single-arm prospective multicentre enrolled as first-line treated at 9 centres. primary outcome measures included functional independence 90 days (mRS 0–2), symptomatic intracranial haemorrhage...
To evaluate the effect of dl-3-N-butylphthalide (NBP) on new cerebral microbleeds (CMBs) in patients with acute ischemic stroke (AIS).We will prospectively enroll AIS admitted to center Jingjiang People's Hospital. Qualified participants be randomly assigned either NBP group (NBP injection) or control injection placebo) a ratio 1:1. Patients complete brain magnetic resonance imaging within 48 hours and 14 days after onset observe CMBs through susceptibility weighted imaging, whether use...
Background: There may be a delay in or poor outcome of endovascular treatment (EVT) among acute ischemic stroke (AIS) patients with large-vessel occlusion (LVO) during off-hours. By using prospective, nationwide registry, we compared the workflow intervals and radiological/clinical outcomes between LVO treated EVT presenting off- on-hours. Methods: We analyzed prospectively collected Endovascular Treatment Key Technique Emergency Work Flow Improvement Acute Ischemic Stroke (ANGEL-ACT) data....
Existing online multi-label classification works cannot well handle the label thresholding problem and lack regret analysis for their algorithms. This paper proposes a novel framework of adaptive algorithms classification, with aim to overcome drawbacks existing methods. The key feature our is that both scoring models are included as important components classifier incorporated into one optimization problem. Further, in order establish relationship between models, loss function derived,...
Online active learning can both effectively reduce the labeling cost and process large-scale or streaming data, thus it has become an important research area in machine learning. However, there are few online studies regarding multi-label classification tasks. And existing algorithms either ignore label correlation cardinality inconsistency, only be applied to a particular application field. In this paper, we propose novel algorithm, termed MSGDA overcome drawbacks of algorithms. Our hybrid...
Objective To evaluate the effects of renin-angiotensin system (RAS) blockades [angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II type 1 receptor blockers (ARB)]on contrast-induced nephropathy (CIN) in patients undergoing angiography. Methods Pubmed, Embase, Cochrane library, Wanfang database CNKI were searched. The literature limited range was from their start year to July 2015. Randomized controlled trials (RCTs) non-randomized influencing CIN assessed. Two...
