Q1. What is linear regression
Ans. 
Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables.
• Linear regression aims to find the best-fitting straight line that describes the relationship between variables.

• It is commonly used for predicting numerical values based on input features.

• The equation for a simple linear regression model is y = mx + b, where y is the dependent vari...read more

Q2. What is support vector machine
Ans. 
Support Vector Machine (SVM) is a supervised machine learning algorithm used for classification and regression tasks.
• SVM finds the hyperplane that best separates different classes in the feature space

• It works by maximizing the margin between the closest data points from different classes

• SVM can handle non-linear data by using kernel functions to map data into higher-dimensional space

• Examples: classifying emails as spam...read more

Q1. What is difference between object detection and segmentation in image
Ans. 
Object detection identifies objects in an image, while segmentation assigns a label to each pixel in the image.
• Object detection involves identifying and locating objects within an image, often using bounding boxes.

• Segmentation assigns a class label to each pixel in the image, creating a pixel-wise mask for each object.

• Object detection is typically used when the goal is to identify and locate multiple objects in an imag...read more

Q2. Technology used in camera sensor
Ans. 
Camera sensors use various technologies such as CMOS and CCD to capture images.
• CMOS (Complementary Metal-Oxide-Semiconductor) sensors are commonly used in modern digital cameras for their low power consumption and high image quality.

• CCD (Charge-Coupled Device) sensors are another type of sensor used in some cameras, known for their high-quality images but higher power consumption.

• Other technologies used in camera senso...read more
