Boosting is a machine learning ensemble technique that combines multiple weak learners to create a strong learner.
Boosting iteratively trains a series of weak learners, where each subsequent learner focuses on the mistakes made by the previous ones.
Popular boosting algorithms include AdaBoost, Gradient Boosting, and XGBoost.
Boosting is often used in classification and regression problems to improve predictive performan
Bagging is a machine learning ensemble technique where multiple models are trained on different subsets of the training data and their predictions are combined.
Bagging stands for Bootstrap Aggregating
It helps reduce overfitting by combining the predictions of multiple models
Random Forest is a popular algorithm that uses bagging
Deep learning is called 'deep' because it involves multiple layers of neural networks.
Deep learning uses multiple layers of neural networks to learn and make decisions.
Each layer in a deep learning model extracts different features from the input data.
The depth of the neural network refers to the number of layers it has.
Deep learning models are able to learn complex patterns and relationships in data.
Examples of deep l...
Logistic regression is a statistical model used to predict the probability of a binary outcome based on one or more predictor variables.
Logistic regression is used when the dependent variable is binary (e.g. 0 or 1).
To remove multicollinearity in logistic regression, you can use techniques like dropping one of the correlated variables or using regularization methods like Lasso or Ridge regression.

There are three types of confusion matrices: binary, multi-class, and multi-label.
Binary confusion matrix is used for classification problems with two classes.
Multi-class confusion matrix is used for classification problems with more than two classes.
Multi-label confusion matrix is used for problems where each instance can belong to multiple classes.
Example: In a binary classification problem, the confusion matrix woul...
Types of errors in software development
Syntax errors: Mistakes in the code structure that prevent it from running
Logic errors: Flaws in the algorithm that lead to incorrect results
Runtime errors: Issues that occur while the program is running, such as division by zero
Semantic errors: Errors in the meaning of the code that may not be caught by the compiler
Dependency Injection is a design pattern where components are given their dependencies rather than creating them internally.
Dependency Injection helps in achieving loose coupling between classes.
It allows for easier testing by providing mock dependencies.
There are three types of Dependency Injection: Constructor Injection, Setter Injection, and Interface Injection.

Join in SQL is used to combine rows from two or more tables based on a related column between them.
Join is used to retrieve data from multiple tables based on a related column
Types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.column = table2.column
Not so tough and you will learn a lot of things that are new to you
The duration is about 90 minute
I applied via Referral and was interviewed in Apr 2023. There were 3 interview rounds.
The apptitude test is very easy.
First 20 questions are realated to image
Means select the image to make puzzle 🧩
Then 5 questions apptitude of related train &speed
Then 5 logical reasoning means series of number, interest,etc.
Then 15 psuedo code question
And you must have to want 60%marks of psuedo code
All psuedo code have from c language you can practice from google
They are provide 3 month unpaid training
And then next three month they giving you 15k
And they want to be 3 lakh check from you as a community of company means if you are want to leave and break the bond of company which have 4 year then you will be....pay
It is not mandatory that your account having money you can give this company check any of your bank.
Thankyou
Odometer can be measured by counting the number of rotations of the wheel and multiplying it by the circumference of the wheel.
Measure the circumference of the wheel
Count the number of rotations of the wheel
Multiply the circumference by the number of rotations to get the distance traveled
Use sensors to automate the process

An int is typically 4 bytes in size.
The size of an int can vary depending on the programming language and platform.
In C and C++, an int is typically 4 bytes on most platforms.
In Java, an int is always 4 bytes.
In Python, an int can be any size depending on the value it represents.
