I am not sure if I do understand the result of g = mixture.GMM(n_components=1).fit(X) logProb, _ = g.score_samples(X) where the first one (logProb) should be Log probabilities of each data point in X so applying exponent I should get bac...

GmMYB176 is an R1 MYB transcription factor that regulates multiple genes in the isoflavonoid biosynthetic pathway, thereby affecting their levels in soybean roots. While GmMYB176 is important for isoflavonoid synthesis, it is not sufficient for the funct
MS Student at Health Tech4 人赞同了该文章 Guassian Model Gaussian Single Model Guassian probability model is widely used in machine learning. The density function of single Guassian is: f(x)=12πσexp(−(x−μ)22σ2) μ is the mean and σ is the variance. X∼N(μ,σ2) means ...
[32] combined VMF and Student’s t distributions to model the orientation and position of the point cloud. Min et al. [9] proposed a rigid HMM-based registration method for computer-assisted orthopedic surgery, where one point cloud was considered as an HMM composed of GMM and VMF ...

Statistically significant between two samples were determined by comparing means using Student's t test (one-tail, unpaired) with P < 0.01. All experiments were performed at least four times with similar results. Reporting summary. Further information on research design is available in the Nature ...
