I applied via LinkedIn and was interviewed before Feb 2023. There were 2 interview rounds.
Supervised models include linear regression, logistic regression, decision trees, random forests, support vector machines, and neural networks.
Linear regression: used for predicting continuous outcomes
Logistic regression: used for binary classification
Decision trees: used for classification and regression tasks
Random forests: ensemble method using multiple decision trees
Support vector machines: used for classification ...
It was an half hour test 20 questions purely based on ML and statistical knowledge.
Precision and recall are evaluation metrics used in machine learning to measure the performance of a classification model.
Precision is the ratio of correctly predicted positive observations to the total predicted positive observations.
Recall is the ratio of correctly predicted positive observations to the all observations in actual class.
Precision is important when the cost of false positives is high, while recall is i...

OOPs (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPs focuses on creating objects that interact with each other to solve complex problems.
Key principles of OOPs include encapsulation, inheritance, polymorphism, and abstraction.
Encapsulation involves bundling data and methods that operate on the data into a single unit (object).
Inheritance allo...
SOLID principles are a set of five design principles in object-oriented programming to make software more maintainable, flexible, and scalable.
Single Responsibility Principle (SRP) - A class should have only one reason to change.
Open/Closed Principle (OCP) - Software entities should be open for extension but closed for modification.
Liskov Substitution Principle (LSP) - Objects of a superclass should be replaceable with...

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, yes or no).
It estimates the probability that a given input belongs to a certain category.
It uses the logistic function to model the relationship between the dependent variable and independent variables.

Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables.
Linear regression is used to predict the value of a dependent variable based on the value of one or more independent variables.
It assumes a linear relationship between the independent and dependent variables.
The goal of linear regression is to find the best-fitting line that repres...

Transformers are models used in natural language processing (NLP) that learn contextual relationships between words.
Transformers use self-attention mechanisms to weigh the importance of different words in a sentence.
They have revolutionized NLP tasks such as language translation, sentiment analysis, and text generation.
Examples of transformer models include BERT, GPT-3, and RoBERTa.
Hyperparameter tuning is the process of selecting the best set of hyperparameters for a machine learning model.
Hyperparameters are parameters that are set before the learning process begins, such as learning rate, number of hidden layers, etc.
Hyperparameter tuning involves trying out different combinations of hyperparameters to find the ones that result in the best model performance.
Techniques for hyperparameter tuning...

Use SELECT statement with DATE_FORMAT function in SQL to print date in desired format.
Use SELECT DATE_FORMAT(date_column, 'desired_format') FROM table_name;
Replace 'date_column' with the column containing the date data and 'desired_format' with the format you want to print the date in.
Example: SELECT DATE_FORMAT(date_column, '%Y-%m-%d') FROM table_name;

Machine learning is a branch of artificial intelligence that focuses on developing algorithms and models that can learn from and make predictions or decisions based on data.
Machine learning involves training algorithms to learn patterns from data and make predictions or decisions.
It can be supervised, unsupervised, or semi-supervised learning.
Examples include recommendation systems, image recognition, and natural langu
A cloud platform is a service that allows users to store, manage, and process data remotely.
Cloud platforms provide scalable and flexible storage solutions
They offer various services such as computing power, databases, and analytics tools
Examples include Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform
A pointer is a variable that stores the memory address of another variable.
Pointers are used to access and manipulate memory directly.
They are commonly used in programming languages like C and C++.
Example: int *ptr; // declaring a pointer variable
