Witryna20 lip 2024 · The notion of an imbalanced dataset is a somewhat vague one. Generally, a dataset for binary classification with a 49–51 split between the two variables would not be considered imbalanced. However, if we have a dataset with a 90–10 split, it seems obvious to us that this is an imbalanced dataset. Clearly, the boundary for … Witryna30 lip 2024 · Hi, I am trying to use audio data from interviews for binary classification through converting my dataset into spectrograms before feeding into CNN for classification. Firstly, the audio data have different duration i.e., 7 min-30 min and the dataset is imbalanced.
