Background The hypothesis that the LDA (low-dose-aspirin) could improve ovarian and uterine perfusion induced clinicians to administer it in women undergoing IVF. Unfortunately, no studies have shown significant differences in terms of pregnancy rate among patients treated or untreated with LDA. The absence of proven clinical benefits of LDA supplementation, led us to wonder whether aspirin, ad...

In machine learning, linear discriminant analysis (LDA) is a popular dimension reduction method. In this paper, we first provide a new perspective of LDA from an information theory perspective. From this new perspective, we propose a new formulation of LDA, which uses the pairwise averaged class covariance instead of the globally averaged class covariance used in standard LDA. This pairwise (av...

BACKGROUND Overt bleeding associated with low dose aspirin (LDA) is well-recognized, little attention is given to the possibility of association between LDA and occult bleeding, although this is known to occur in healthy volunteers. LDA is used increasingly in primary and secondary prevention of a number of medical conditions, many of which are common in older people, as is anemia. Anemia in ol...

Hyper-parameters play a major role in the learning and inference process of latent Dirichlet allocation (LDA). In order to begin the LDA latent variables learning process, these hyperparameters values need to be pre-determined. We propose an extension for LDA that we call ‘Latent Dirichlet allocation Gibbs Newton’ (LDA-GN), which places non-informative priors over these hyper-parameters and use...

OBJECTIVE To evaluate maternal and neonatal plasma concentrations of acetylsalicylic acid and salicylic acid and the neonatal endogenous prostanoid formation during low-dose aspirin prophylaxis (LDA; 100 mg daily) in pregnant women. METHODS Concentrations of acetylsalicylic acid and salicylic acid in maternal plasma after at least 4 weeks of LDA (n = 14) and in umbilical cord plasma of newbor...

The milk yield and survival of 91 Holstein-Friesian dairy cows that had had a left-displaced abomasum (LDA) corrected laparoscopically were compared with those of 193 control cows matched for herd, parity and calving date. Ninety per cent of the LDA treatments were performed within four weeks after calving. The risk of being culled during the whole observational period of at least three years w...

In this work, we investigate the well-known classification algorithm LDA as well as its close relative SPRT. SPRT affords many theoretical advantages over LDA. It allows specification of desired classification error rates α and β and is expected to be faster in predicting the class label of a new instance. However, SPRT is not as widely used as LDA in the pattern recognition and machine learnin...

Latent Dirichlet Allocation (LDA) is a popular topic modeling technique for hidden semantic discovery of text data and serves as fundamental tool analysis in various applications. However, the LDA model well training process may expose information data, thus bringing significant privacy concerns. To address issue LDA, we systematically investigate protection main-stream algorithm based on Colla...
