Identify Keywords for Stack Exchange Questions
ثبت نشده
چکیده
We leveraged a wide range of knowledge in machine learning and information retrieval to develop a robust keywords identification system. In particular, we adapted the Tf-Idf heuristic for feature selection, investigated linear regression, logistic regression, and SVM for predicting number of keywords (tags), and also implemented NaiveBayes, Labeled Latent Dirichlet Allocation(L-LDA) algorithms for identifying keywords. After varies experiments, we analysed the results and derived conclusions.

متن کاملModeling and experimental study on the sealing gasket of proton exchange membrane fuel cells
In this study cross section geometry and material of gasket in proton exchange membrane (PEM) fuel cells have been investigated to achieve optimized fuel cell in terms of energy efficiency. The role of gaskets in fuel cells is sealing of gas flow channels and preventing from combination of them. In a PEM stack, gasket with approved geometry that suffers more stress has better sealing. For this ...
