The BiTeM group participated in the first TREC Medical Records Track in 2011 relying on a strong background in medical records processing and medical terminologies. For this campaign, we submitted a baseline run, computed with a simple free-text index in the Terrier platform, which achieved fair results (0.468 for P10). We also performed automatic text categorization on medical records and buil...

In this paper, the ARIMA(2,1,2) model and LSTM are used to predict Shanghai Composite Index, then IOWGA operator is establish a combined forecast further improve accuracy. The empirical results show that errors of forecasting lower than those individual models, average precision better models. addition, Index will fluctuate slightly in next five trading days.

We present a parameter free and monotonic alternative to the parametric variable precision model of rough set data analysis. The proposed model is based on the well known PRE index λ of Goodman and Kruskal. Using a weighted λ model it is possible to define a two dimensional space based on (Rough) sensitivity and (Rough) specificity, for which the monotonicity of sensitivity in a chain of sets i...

Unmanned Aerial Vehicles (UAV)-based remote sensing offers great possibilities to acquire in a fast and easy way field data for precision agriculture applications. This field of study is rapidly increasing due to the benefits and advantages for farm resources management, particularly for studying crop health. This paper reports some experiences related to the analysis of cultivations (vineyards...

With the increase in the amount of video that is broadcast daily, there is an increasing need for storage of video in a systematic way for future reuse and retrieval. In particular, from the viewpoint of importance and usability, it is desirable to index news videos. For adequate automatic indexing based on the text information in the video, it is not sufficient to apply the simple index extrac...

Body Mass Index is associated with endurance performance in athletes. Reported and measured values of body mass and body height in 1,618 endurance athletes (1,358 men, 260 women) showed that men and women both underestimated their body mass and overestimated their body height, leading to an underestimation of Body Mass Index. There were age and sex differences in estimates of height and weight;...

Background: A precision health care approach is needed in the context of the healthcare system, especially as an effort to improve the self-management activities of diabetes patients. Thus, the purpose of this study was to explore the perception of the possibility of implementing a precision health care program in hospitals through interviews with policymakers and health professionals. Methods...

PURPOSE To determine which version of the Visual Function Index-14 (VF-14) most precisely measured cataract surgery outcomes, rescale the VF-14 using Rasch analysis, and create a short-form version for comparison. SETTING Flinders Medical Centre, Adelaide, South Australia, Australia. METHODS In this cohort study incorporating questionnaire development, participants were drawn from the catar...

As one of the key methods to extract content semantics and structure from audio, automatic audio classification, especially for a speech and a music, is valuable for content-based audio retrieval, video summary and retrieval, and spoken document retrieval, etc. Because hidden Markov model (HMM) can well model audio signal’s time statistical properties, a left-right discrete HMM is proposed to c...
