Question: Which Machine Learning Algorithm Is Best?

Which algorithms are used to predict continuous values?

Basically, predicting a continuous variable is termed as regression.

There are a no of regression algorithms like ridge and lasso regression you may want to check out….Linear Regression.Logistic Regression.Polynomial Regression.Stepwise Regression.Ridge Regression.Lasso Regression.ElasticNet Regression,.

What is Overfitting machine learning?

Overfitting in Machine Learning Overfitting refers to a model that models the training data too well. Overfitting happens when a model learns the detail and noise in the training data to the extent that it negatively impacts the performance of the model on new data.

How many algorithms are there in machine learning?

four typesThere are four types of machine learning algorithms: supervised, semi-supervised, unsupervised and reinforcement.

Which algorithm is used for classification?

When most dependent variables are numeric, logistic regression and SVM should be the first try for classification. These models are easy to implement, their parameters easy to tune, and the performances are also pretty good. So these models are appropriate for beginners.
