I applied via Approached by Company and was interviewed in May 2023. There were 3 interview rounds.
Sigmoid is used for binary classification while softmax is used for multi-class classification.
Sigmoid function outputs values between 0 and 1, suitable for binary classification tasks.
Softmax function outputs a probability distribution over multiple classes, summing up to 1.
Sigmoid is used in the output layer for binary classification, while softmax is used for multi-class classification.
Softmax is the generalization
An activation function is a mathematical function that determines the output of a neural network.
Activation functions introduce non-linearity to the neural network, allowing it to learn complex patterns in the data.
Common activation functions include sigmoid, tanh, ReLU, and softmax.
The choice of activation function can impact the performance and training speed of the neural network.

I applied via Recruitment Consulltant and was interviewed before Aug 2021. There was 1 interview round.
CNN is used for image recognition while MLP is used for general classification tasks.
CNN uses convolutional layers to extract features from images while MLP uses fully connected layers.
CNN is better suited for tasks that require spatial understanding like object detection while MLP is better for tabular data.
CNN has fewer parameters than MLP due to weight sharing in convolutional layers.
CNN can handle input of varying

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 Referral and was interviewed before May 2023. There was 1 interview round.
Feature selection methods help in selecting the most relevant features for building predictive models.
Feature selection methods aim to reduce the number of input variables to only those that are most relevant.
Common methods include filter methods, wrapper methods, and embedded methods.
Examples include Recursive Feature Elimination (RFE), Principal Component Analysis (PCA), and Lasso regression.
Central Limit Theorem states that the sampling distribution of the sample mean approaches a normal distribution as the sample size increases.
The Central Limit Theorem is essential in statistics as it allows us to make inferences about a population based on a sample.
It states that regardless of the shape of the population distribution, the sampling distribution of the sample mean will be approximately normally distribut...
