- Q2. What is LDA and represent the LDA using diagram ?
- Ans.
LDA stands for Latent Dirichlet Allocation, a topic modeling technique used in natural language processing.
LDA is a generative statistical model that allows sets of observations to be explained by unobserved groups that explain why some parts of the data are similar.
It is commonly used in text mining to extract topics from a collection of documents.
LDA assumes that each document is a mixture of a small number of topics...
- Q3. How do you implement a machine learning algorithm based on a given case study, and which algorithm do you choose and why?
- Ans.
To implement a machine learning algorithm based on a case study, choose an algorithm based on the type of data and problem to be solved.
Understand the problem statement and the type of data available.
Preprocess the data by handling missing values, encoding categorical variables, and scaling features.
Split the data into training and testing sets.
Choose an appropriate algorithm based on the problem type (classification, ...

- Q1. Sorting algorithm
- Ans.
A sorting algorithm is a method of arranging elements in a specific order.
Sorting algorithms can be categorized as comparison-based or non-comparison-based.
Common sorting algorithms include bubble sort, insertion sort, selection sort, merge sort, quicksort, and heapsort.
Efficiency of sorting algorithms is measured by their time complexity, space complexity, and stability.
Example: Sorting an array of strings in alphabet

- Q1. Design fan.What is bm? What is nozzle?
- Ans.
BM stands for Blade Material. Nozzle is a device that directs or controls the flow of a fluid.
BM refers to the material used to make the blades of a fan. It can be plastic, metal, or wood.
Nozzle is a component that is used to control the flow of a fluid, such as air or water. It can be found in various devices, such as a garden hose or a spray bottle.
In a fan, the nozzle is the part that directs the air flow in a speci...

- Q1. 1. how is motor connected to PLC 2.use of PID controller 3. which motor is used in fans 4. Inrush current 5. Is starting current more or running current
- Ans.
Motor is connected to PLC using motor starters or variable frequency drives. PID controller is used for precise control. Fans typically use induction motors. Inrush current is the initial surge of current when a motor starts. Starting current is usually higher than running current.

- Q1. What is polymorphism in C++?
- Ans.
Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.
Polymorphism is achieved through virtual functions and function overriding.
It allows for more flexibility and extensibility in code.
Example: A base class 'Shape' with virtual function 'draw', and derived classes 'Circle' and 'Square' that override 'draw'.
- Q2. Explain how different kind of motions are achieved in a Drone
- Ans.
Different motions in a drone are achieved through varying the speed and direction of the propellers.
Changing the speed of the propellers controls the altitude of the drone.
Varying the speed of propellers on different sides of the drone allows it to move forward, backward, left, or right.
Adjusting the speed of the propellers diagonally creates rotational motion for turning.
Combining these motions enables the drone to pe
- Q3. Linux Commands?
- Q4. Explain PID controller and its tunning.
- Ans.
PID controller is a control loop feedback mechanism used in systems to control process variables.
PID stands for Proportional, Integral, Derivative.
Proportional term responds to the current error.
Integral term corrects the accumulated error over time.
Derivative term predicts future error based on current rate of change.
Tuning involves adjusting the three parameters (P, I, D) to achieve desired system response.
Example: I...
