在logistic regression的优化过程中,目标loss最小(maximum likelihood),这样会倾向于让w变大,使得所有样本的概率尽可能接近1,但这样实际上是overconfident。 w变大,让样本概率接近1,如下图: 这两种overfitting的表现都是w较大。 而linear regression只有第一种overfitting,所以说ove
MFCC as studied by earlier researchers provide 75% efficiency results to get more efficient results is it required to use more features of the sound. This trained dataset is used to study the emotions of the users that can be further used in machine learning.RajniDr. Ajit Singh...

a Naive Bayes classifier will converge quicker than discriminative models like logistic regression, so you need less training data. And even if the NB assumption doesn’t hold, a NB classifier still often does a great job in practice. A good...
Current machine learning classifiers have successfully been applied to whole-genome sequencing data to identify genetic determinants of antimicrobial resistance (AMR), but they lack causal interpretation. Here we present a metabolic model-based machine l

I recommend Weka to beginners in machine learning because it lets them focus on learning theprocess of applied machine learningrather than getting bogged down by themathematicsand theprogramming— those can come later. In this post, I want to show you how easy it is to load a dataset, run ...
This is a simple, fast, for live audio in realtime, customizable machine learning sound classifier. MobileNetV2; light weight CNN model for mobile is used. (new) AlexNet based lighter/faster CNN model is also provided. Tensorflow graph for runtime faster prediction, and for portability. ...
Machine learning has created a drastic impact in every sector that has integrated it into their business processes. Sectors like education, healthcare, retail, manufacturing, banking services, and more have already started investing in their initiatives involving machine learning. So why not seize upon...
