Text Classification in NLP using Cross Validation and BERT

Mlearning.ai

Figure 4 Data Cleaning Conventional algorithms are often biased towards the dominant class, ignoring the data distribution. Figure 11 Model Architecture The algorithms and models used for the first three classifiers are essentially the same. In addition, each tree in the forest is made up of a random selection of the best attributes.
