# 2. Integration of YOLOv8 Model with Natural Language Processing Technologies

### 2.1 Principles and Advantages of the YOLOv8 Model

#### 2.1.1 The Network Structure and Training Methods of YOLOv8

The YOLOv8 model employs a network structure known as Cross-Stage Partial Connections (CSP), which divides the feature maps into multiple stages and connects only the feature maps of adjacent stages, thereby reducing the amount of computation. Additionally, YOLOv8 utilizes the Path Aggregation Network (PAN) module, which fuses feature maps from different stages to enhance the model's feature extraction capabilities.

During training, YOLOv8 adopts a strategy called Bag of Freebies (BoF), which includes a series of data augmentation techniques and regularization methods to improve the model's generalization capabilities. The BoF strategy encompasses Mosaic data augmentation, MixUp data augmentation, CutMix data augmentation, adaptive batch normalization, and DropBlock regularization.
