There are a lot of small noises in a photo during storage. Which operation is the best for noise reduction?
Through the image algorithm, the foreground and background of a person who takes a picture taken by an ordinary mobile phone are segmented, and then the () operation is performed on the () part, which can achieve the same effect as a SLR camera.
(Judgment) The background difference method is to use the current frame in the image sequence and the background reference model for subtraction, which can realize the detection of moving objects in the image.
Image feature library extraction is a kind of dimensionality reduction idea, can it effectively reduce the amount of image data?
The Gaussian filter of the same size has better denoising effect than the mean filter.
(Judgment) Image feature extraction is a dimensionality reduction idea, which can effectively reduce the amount of image data.
How many sources does the data set in ModelArts data management have? (Multiple Choices)
The bag-of-words model is the earliest text vectorization method with words as the basic processing unit. Which of the following options is not the bag of words model.
Overall, Huawei’s development strategy for artificial intelligence is based on continuous investment in basic research and AI training to create a full-stack, full-scenario AI solution and an open global ecosystem.
What is the correct description of probability and likelihood?
In Chinese, the part-of-speech of a word is often not fixed. Generally speaking, words with the same homonym and different shapes have different grammars in different scenes, which brings great difficulties to the part-of-speech tagging.
The fully connected layer acts as a classifier in the convolutional neural network.
Phonetics is a branch of the language coast and is a subject that studies human language.
When taking light, the face is relatively dark. Use gamma correction to enhance the image to achieve a clear light effect. Which of the Y limit can be selected. (Single choice)
(Judgment) The original value of the recording pixel is S, The pixel value after the change is D. The mapping function of gray scale change is d=ks. When k>1, gray scale stretching of the dark part of the image can be achieved.
Which of the following options is the API corresponding to the speech synthesis interface?
What are the main functions of MoXing? (Single choice)
The TF algorithm is a statistical word that appears in how many documents in the document set. The basic idea is that if a word appears in fewer documents, the stronger the ability to distinguish documents.
TF-IDF is a calculation method based on statistics, commonly used to evaluate the importance of a word in a document set to all documents.
Huawei Cloud Face Recognition Service is an intelligent service that uses computers to process and analyze face images based on human facial feature information. It is an intelligent service that performs identity recognition. What types of current Huawei Cloud Face Recognition provide Subservice?
Which of the following are hidden units.
(Judgment) TF-IDF is a calculation method based on statistics, which is often used to evaluate the importance of a word in a document set to all documents.
NNLM In the model, what is the activation function used by the network output layer?
The Gaussian model is to accurately quantify things with a Gaussian density function and decompose a thing into several models based on Bernoulli distribution.
What is the difficulty of speech recognition?
In natural language processing, the most commonly used deep learning algorithm is CNN, because of its memory function?
