When creating document representations, it ignores word order and uses a linear softmax classifier. FastText is very efficient to train while achieving state-of-the-art results on a variety of multi-class classification benchmarks, and it is often several orders of magnitude faster than competing ...
It really depends on our “goal” and our dataset. Classification Accuracy (or misclassification error) makes sense if our class labels are uniformly distributed. Even better, we can compute the ROC area under the curve (even for multi-class sytems), e.g., have a look at the niceICML’04...
Both the house price model and the text classification model arelinearmodels. Depending on the nature of your data and the problem you are solving, you can also usedecision treemodels,generalized additivemodels, and others. You can find out more about the models inTasks. ...
machine learning continues to evolve rapidly. Breakthroughs in AI and ML occur frequently, rendering accepted practices obsolete almost as soon as they're established. One certainty about thefuture of machine learningis its continued central role in the 21st century, transforming how work is done...

Classification Regression 2) Unsupervised Learning Unsupervised learning is a learning method in which a machine learns without any supervision. The training is provided to the machine with the set of data that has not been labeled, classified, or categorized, and the algorithm needs to act on tha...

LDA is mainly used in classification problems where you have a categorical output variable. It allows both binary classification and multi-class classification. The standard LDA model makes use of the Gaussian Distribution of the input variables. You should check the univariate distributions of each ...
