SCM Garments Data Analyst Interview Questions and Answers

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.

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...read more

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...read more

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...read more
