    • Evaluated model performance using metrics like accuracy, precision, and recall

  • Answered by AI
  • Q2. What is Linnear regression ?
  • Ans. 

    Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables.

    • Linear regression aims to find the best-fitting straight line that describes the relationship between variables.

    • It is commonly used for prediction and forecasting in various fields such as finance, economics, and social sciences.

    • The equation for linear regression is typically repre...

  • Answered by AI
  • Q3. Diff betn linnear and logistic regression?
  • Ans. 

    Linear regression is used for continuous variables while logistic regression is used for binary classification.

    • Linear regression predicts continuous values while logistic regression predicts probabilities.

    • Linear regression uses a linear equation to model the relationship between the independent and dependent variables.

    • Logistic regression uses the logistic function to model the probability of a binary outcome.

    • Linear reg...

  • Q4. Diff betn random forest vs decision tree algorithm?
  • Ans. 

    Random forest is an ensemble learning method that uses multiple decision trees to make predictions.

    • Random forest is a collection of decision trees that are trained on different subsets of the data.

    • Decision tree is a single tree-like structure that makes decisions based on features of the data.

    • Random forest reduces overfitting by averaging the predictions of multiple trees.

    • Decision tree can be prone to overfitting if no...

  • Answered by AI
  • Q5. Formula for precision?
  • Ans. 

    Precision is the ratio of correctly predicted positive observations to the total predicted positive observations.

    • Precision = True Positives / (True Positives + False Positives)

    • It is a measure of the accuracy of the positive predictions made by the model.

    • A high precision indicates that the model is good at predicting positive cases without many false positives.

  • Answered by AI
  • Q6. Common metrics to find accuracy of linnear regression model and Logistic regression model?
  • Ans. 

    Common metrics for linear and logistic regression models are R-squared and confusion matrix respectively.

    • For linear regression model, common metric is R-squared which measures the proportion of the variance in the dependent variable that is predictable from the independent variables.

    • For logistic regression model, common metric is confusion matrix which includes metrics like accuracy, precision, recall, and F1 score to ...

  • Answered by AI
  • Q7. What is recall and F1?
  • Ans. 

    Recall is the ratio of correctly predicted positive observations to the all observations in actual class. F1 is the harmonic mean of precision and recall.

    • Recall is calculated as TP / (TP + FN)

    • F1 score is calculated as 2 * (precision * recall) / (precision + recall)

    • Recall is important in scenarios where false negatives are costly, like in medical diagnosis

  • Answered by AI
  • Q8. Tell me example of ensemble technique?
  • Ans. 

    Ensemble technique combines multiple models to improve prediction accuracy.

    • Ensemble methods include bagging, boosting, and stacking

    • Random Forest is an example of ensemble technique using bagging

    • Gradient Boosting Machine (GBM) is an example of ensemble technique using boosting
