Which of the following is the operation performed by the code mox.file.exists (‘ obs :// bucket_name /test01’)?
- A . Create a folder
- B . Read a file on OBS
- C . List an OBS path
- D . Check if the folder exists
What types of phonetics are there? (Multiple choice)
- A . Articulation and Phonetics
- B . Auditory Phonetics
- C . Acoustic Phonetics
- D . Phonology and phonetics
Which of the following options is a method for training static word vectors?
- A . Fasttext
- B . ELMO
- C . BERT
- D . GPT
Which of the following types of operators does the CCE operator library contain? (Multiple choice)
- A . Matrix multiplication
- B . Control
- C . Vector class
- D . Convolution
In the field of deep learning, which of the following options are correct? (Multiple choice)
- A . Update all parameter values through learning rate and gradient value to increase the loss value of the network
- B . Gradient descent is actually to find the partial derivative (gradient) of the loss value with respect to all parameters. The meaning of the gradient is the direction of the fastest change.
- C . Update all parameter values through learning rate and gradient value to reduce the loss value of the network
- D . Learning Rate (LR) is an important hyperparameter in gradient descent
Forward propagation can complete the update of parameters.
- A . True
- B . False
Which of the following options are correct about the description of rectangular window and Hamming window? (Multiple choice)
- A . The rectangular window has better smoothness, but the waveform details are lost and leakage occurs (Yes, new version PPT page 253)
- B . The main lobe width of the Hamming window is larger than that of the rectangular window, and has a higher spectral resolution (the rectangular frame has a higher spectral resolution)
- C . The Hamming window can effectively overcome the leakage phenomenon and has the widest application range.
- D . The side lobe peak of the rectangular window is large, so its spectrum leakage is more serious
In the grayscale change experiment of image preprocessing, the gamma change function is defined as follows:
Xxxxxxxxxx
Def gamma_trans (img, gamma):
Gamma_list = [ np.power (x/255.0,gamma)*255.0 for x in range(256)]
Gamma_table = np.round ( np.array ( gamma_list )). astype (np.uint8)
Return cv2.LUT(img , gamma_table )
When the gamma value is 0.5, the bright part is stretched and the dark part is compressed.
- A . True
- B . False
