3.2. Logistic Regression Classifier: When we’re talking about classifying things, one common go-to is the Logistic Regression Classifier. Inside its workings, there’s a special knob calledC, and it’s connected to something called the‘regularization parameter,’let’s call itλ(that’s a Gr...
To further improve the design efficiency, the secondary optimization level called hyperparameter tuning will be further investigated. DA, SVM, k-NN, decision tree (Tree), logistic regression (LR), random forest tree (RF) and neural network (NN) are evaluated. The k-NN provided 96.47% of ...
This tutorial shows how SynapseML can be used to identify the best combination of hyperparameters for your chosen classifiers, ultimately resulting in more accurate and reliable models. In order to demonstrate this, we'll show how to perform distributed randomized grid search hyperparameter tuning ...
At the same time, optimal hyperparameter tuning process plays a vital role to enhance overall results. This study introduces a Teacher Learning Genetic Optimization with Deep Learning Enabled Cyberbullying Classification (TLGODL-CBC) model in Social Media. The proposed TLGODL-CBC model intends to ...

You have created the Logistic Regression model with some random hyperparameter values. The hyperparameters that you used are: penalty : Used to specify the norm used in the penalization (regularization). dual : Dual or primal formulation. The dual formulation is only implemented for l2 penalty wi...
In the context of hyperparameter tuning in the app, a point is a set of hyperparameter values, and the objective function is the loss function, or the classification error. For more information on the basics of Bayesian optimization, see Bayesian Optimization Workflow. You can specify how the...
For example, a logistic regression model has different solvers that are used to find coefficients that can give us the best possible output. Each solver uses a different algorithm to find an optimal result, and none of these algorithms are strictly better than the other. It is difficult to te...
