Cross validation is a technique used to assess the performance of a predictive model by splitting the data into training and testing sets multiple times.
Cross validation helps to evaluate how well a model generalizes to new data.
It involves splitting the data into k subsets, training the model on k-1 subsets, and testing it on the remaining subset.
Common types of cross validation include k-fold cross validation and lea...
I applied via Naukri.com and was interviewed in May 2023. There were 2 interview rounds.
Use a regression algorithm like linear regression or decision tree regression.
Consider using linear regression if the relationship between variables is linear.
Decision tree regression can handle non-linear relationships between variables.
Evaluate the performance of different algorithms using cross-validation.
Consider the interpretability of the model when choosing an algorithm.
I was interviewed in May 2022.

The interview happened in the evening. It was an online video call.
The interviewer was very cooperative. I would say it was rather a discussion session between us.
Given a linked list where each node contains two pointers: one pointing to the next node and another random pointer that can point to any node within the list (or ...

Tip 1 : Start your preparation early. Start from the very basics before directly moving onto DSA. Get a grasp of the basics in each topic. Practice different varieties of questions from each topic. I would recommend at least 200 questions of DSA.
Tip 2 : Revise your projects before you attend any interview. This is extremely important. You must be able to clearly explain your project along with your role in the project in layman terms to the interviewer.
Tip 3 : Grind hard to achieve your goals but don't take much stress. There's a long way to go.
Tip 1 : Never, I say never put false things or your friends project in your resume
Tip 2 : Make a 1 page resume. Make your resume in such a way that the interviewer must be able to see the things you want him to see in the very first scan.

Model Gini is a measure of statistical dispersion used to evaluate the performance of classification models.
Model Gini is calculated as twice the area between the ROC curve and the diagonal line (random model).
It ranges from 0 (worst model) to 1 (best model), with higher values indicating better model performance.
A Gini coefficient of 0.5 indicates a model that is no better than random guessing.

XGBoost model is trained by specifying parameters, splitting data into training and validation sets, fitting the model, and tuning hyperparameters.
Specify parameters for XGBoost model such as learning rate, max depth, and number of trees
Split data into training and validation sets using train_test_split function
Fit the XGBoost model on training data using fit method
Tune hyperparameters using techniques like grid search

Gradient descent is an optimization algorithm used to minimize a function by iteratively moving in the direction of steepest descent.
Gradient descent is used to find the minimum of a function by taking steps proportional to the negative of the gradient at the current point.
It is commonly used in machine learning to optimize the parameters of a model by minimizing the loss function.
There are different variants of gradie...
LSTM (Long Short-Term Memory) is a type of recurrent neural network designed to handle long-term dependencies.
LSTM has three gates: input gate, forget gate, and output gate.
Input gate controls the flow of information into the cell state.
Forget gate decides what information to discard from the cell state.
Output gate determines the output based on the cell state.
T-test is a statistical test used to determine if there is a significant difference between the means of two groups.
Mean is the average of a set of numbers, median is the middle value when the numbers are ordered, and mode is the most frequently occurring value.
Mean is sensitive to outliers, median is robust to outliers, and mode is useful for categorical data.
T-test is used to compare means of two groups, mean is used...
Random Forest is an ensemble learning method used for classification and regression tasks.
Random Forest is a collection of decision trees that are trained on random subsets of the data.
Each tree in the forest makes a prediction, and the final prediction is the average (regression) or majority vote (classification) of all trees.
Random Forest helps reduce overfitting and improve accuracy compared to a single decision tre...
