Deep Learning - Computer Vision for Beginners Using PyTorch - NumPy

The video tutorial provides a comprehensive guide to working with the Numpy library, focusing on array creation and manipulation. It covers the benefits of Numpy arrays over Python lists, explains 1D and 2D arrays, and demonstrates how to check their shape. The tutorial also delves into creating arrays using various Numpy functions, specifying data types, and generating multi-dimensional arrays. Advanced techniques such as creating random arrays and identity matrices are also discussed, emphasizing the importance of these methods in data analysis and deep learning.

What is one of the main advantages of using Numpy arrays over Python lists?

• They are more compact and efficient.

• They can store different data types.

• They are easier to read.

• They are more visually appealing.

How do you import the Numpy library with a shorthand alias?

• import numpy as n

• import numpy as nmp

• import numpy as num

• import numpy as np

Which function is used to convert a Python list into a Numpy array?

• np.convert()

• np.tolist()

• np.list()

• np.array()

What parameter is used to specify the data type of a Numpy array?

• dtype

• datatype

• type

• datakind

How can you create a multi-dimensional array in Numpy?

• By using np.multi()

• By passing a series of lists to np.array()

• By using np.dim()

• By using np.create()

Which function is used to create an array filled with ones?

• np.zeros()

• np.full()

• np.empty()

• np.ones()

What does the np.empty() function do?

• Creates an array filled with ones

• Creates an array with random values

• Creates an array filled with zeros

• Creates an array without initializing entries

Which function generates an array with random values between 0 and 1?

• np.rand()

• np.random()

• np.randomize()

• np.random.random()

What is the purpose of the np.linspace() function?

• To create an array of random numbers

• To create an array of zeros

• To create an identity matrix

• To create an array of equally spaced values

How do you create an identity matrix using Numpy?

• np.identity()

• np.eye()

• np.id()

• np.I()
