20 MCQ questions related to Data science and 1 coding ML question.
Overfitting and underfitting are common problems in machine learning where a model performs too well on training data but poorly on unseen data, or performs poorly on both training and unseen data due to oversimplification.
Overfitting occurs when a model learns the noise in the training data rather than the underlying pattern, leading to poor generalization on unseen data.
Underfitting happens when a model is too simple...
K-fold CV is a technique used to evaluate the performance of a machine learning model by splitting the data into k subsets.
Data is divided into k subsets, with one subset used as the validation set and the rest as training sets.
The process is repeated k times, with each subset used once as the validation data.
The average of the k validation results is used as the final performance metric.
Helps in reducing bias and vari...

Basic coding questions related to data science
Imbalanced data in text analytics can be handled by techniques like oversampling, undersampling, and SMOTE.
Use oversampling to increase the number of instances in the minority class
Use undersampling to decrease the number of instances in the majority class
Use SMOTE to generate synthetic samples for the minority class
Use cost-sensitive learning algorithms to assign higher misclassification costs to the minority class
Use...
