Question

Question 1) You load an image file into a numpy array and look at its shape, which is (433, 650, 3). What does this indicate?

A) The image is 433 pixels high by 650 pixels wide and 3 Mb in size.

B) The image is a color (RGB) image that is 433 pixels high by 650 pixels wide.

C) The image is a grayscale image that is 433 pixels high by 650 pixels wide.

D) The image has 433 red pixels, 650 blue pixels, and 3 green pixels.

Question 2)

You evaluate an image classification model and produce the confusion matrix above. What does this tell you about the model when tested with your validation data? (choose two)

A) The model predicted perfectly with 100% accuracy.

B) The model correctly identified planes more accurately than it did automobiles or trains.

C) The model performed worse than random guess.

D) The model sometimes identifies automobiles as trains.

Note: I need an explanation, please!!!!

Answer 1

Solution Correct answer is B... Numpy is nuncerical python, when an image file is waded into a numpy array, and the print the image using certain instalttausit is alapec observed that à cot choi data is stored in an n-dimensional array as image is Gothing but a set of numbers , In array of datel; 'set of three numbers is known as tuple. Suppose a typce has [125 137 226] toes there Oure every tuple is called pixel it is equal to Red Green Blue every image is com b'ination of pixels arranged in erorisonteel and vertical manner. Ha every pixel hicas data zestawiotch & every pixel has data as [di d2 d3 ] here di represents intensity of red, de represents color intensity of green and d3 represents colors intensity of Blue, e If atype of imape is printed it's uinte , it means unsigned integer of 8 bits, it means every data of pixel ie du de and d3 would be represented using 8 bit 00000000 - 0 II!!!!!! - 255 values so here every pixel has three pixets and all its values can be in range from o-255 No If shape chi image is borse printed then it is (433, 650.21 it means is image is 433 pixels high and 650 pixels widé and 3 represents the channel color le Red,Green Blue
