IEEE/ICACT20250181 Question.19 Questioner: 1308374461@qq.com 2025-02-15 오후 3:59:29	IEEE/ICACT20250181 Answer.19 Answer by Auhor 3120220183@bit.edu.cn 2025-02-15 오후 3:59:29
This paper presents an improved soft threshold function to solve the limitation of traditional hard/soft threshold function. Can you explain specifically how the mathematical design of this improved function balances the advantages of hard thresholds (retaining local features) and soft thresholds (reducing oscillations)?	In the paper, there is an improved definition of the threshold function, λ is the threshold, α is the adjustment parameter, the function is close to the hard threshold when the wavelet coefficient is greater than λ (retain local characteristics, smooth transition when the wavelet coefficient is about equal to λ (reduce oscillation), so as to avoid the discontinuity of the hard threshold and the constant error of the soft threshold
