(4 Questions)

  • Q1. Difference between Tuple and Dictionary
  • Ans. 

    Tuple is an ordered collection of elements, while a dictionary is an unordered collection of key-value pairs.

    • Tuples are immutable, while dictionaries are mutable.

    • Tuples are accessed using indexing, while dictionaries are accessed using keys.

    • Tuples are typically used to store related pieces of data, while dictionaries are used for mapping and lookups.

  • Q2. What is Adjusted R square
  • Ans. 

    Adjusted R square is a statistical measure that represents the proportion of variance in the dependent variable accounted for by the independent variables.

    • Adjusted R square is an extension of R square, which measures the goodness of fit of a regression model.

    • It takes into account the number of predictors in the model and adjusts for the degrees of freedom.

    • Adjusted R square ranges from 0 to 1, where a higher value indic...

  • Q3. Which is better Random forest or XG Boost
  • Ans. 

    Both Random Forest and XG Boost are powerful machine learning algorithms, but their performance depends on the specific problem and data.

    • Random Forest is an ensemble learning method that combines multiple decision trees to make predictions.

    • It is known for its ability to handle high-dimensional data and maintain good performance even with noisy or missing data.

    • XG Boost, on the other hand, is a gradient boosting algorith...

  • Answered by AI
  • Q4. What is Max pooling
  • Ans. 

    Max pooling is a pooling operation that selects the maximum value from a region of the input data.

    • Max pooling is commonly used in convolutional neural networks (CNNs) for feature extraction.

    • It reduces the spatial dimensions of the input data while retaining the most important features.

    • Max pooling helps in achieving translation invariance, making the model more robust to variations in input position.

    • For example, in a 2x...

(2 Questions)

  • Q1. What is supervised learning
  • Ans. 

    Supervised learning is a type of machine learning where the model is trained on labeled data to make predictions or decisions.

    • Uses labeled training data to learn the mapping between input and output variables

    • The model is trained on a dataset where the correct output is known

    • Examples include classification and regression tasks

  • Answered by AI
  • Q2. What is overfitting
  • Ans. 

    Overfitting occurs when a model learns the noise in the training data rather than the underlying pattern.

    • Overfitting happens when a model is too complex and captures noise in the training data.

    • It leads to poor generalization on new, unseen data.

    • Techniques to prevent overfitting include cross-validation, regularization, and early stopping.

    • Example: A decision tree with too many branches that perfectly fits the training d
