It was well designed
Cache is used for temporary storage of data in memory, while persist is used for saving data to disk for long-term storage.
Cache is typically faster as it stores data in memory for quick access.
Persist saves data to disk for durability and long-term storage.
Cache is often used for temporary data that can be recomputed if lost, while persist is used for important data that needs to be retained.
Examples: Using cache for ...
Reverse a sentence using Python
Split the sentence into words using split() method
Reverse the list of words using list slicing
Join the reversed list of words back into a sentence using join() method
I applied via LinkedIn and was interviewed in Jun 2024. There were 3 interview rounds.
Entropy measures randomness in data, while information gain measures the reduction in uncertainty after splitting data.
Entropy is used in decision trees to measure impurity in a dataset before splitting it.
Information gain is used in decision trees to measure the effectiveness of a split in reducing uncertainty.
Entropy ranges from 0 (pure dataset) to 1 (completely impure dataset).
Information gain is calculated as the d...
LSTM for longer sequences, GRU for faster training and less complex models.
Use LSTM for tasks requiring long-term dependencies and memory retention.
Use GRU for faster training and simpler models with fewer parameters.
Consider using LSTM for tasks like language translation or speech recognition.
Consider using GRU for tasks like sentiment analysis or text generation.
Time Series data were given, we have to provide some insights

It contain both Aptitude and Coding about base models and Deep learning too
Different models techniques include linear regression, decision trees, random forests, support vector machines, and neural networks.
Linear regression is used for predicting continuous values.
Decision trees are used for classification and regression tasks.
Random forests are an ensemble method based on decision trees.
Support vector machines are used for classification tasks.
Neural networks are used for complex pattern re
Different performance metrics are used for different types of machine learning models to evaluate their effectiveness.
For classification models, metrics like accuracy, precision, recall, F1 score, and ROC-AUC are commonly used.
For regression models, metrics like mean squared error (MSE), mean absolute error (MAE), and R-squared are commonly used.
For clustering models, metrics like silhouette score and Davies-Bouldin in...
