 - Performance Optimized:
 
   With the help of the underlying PaddlePaddle framework, faster training and
-reduced GPU memory footprint is achieved. Notably, Yolo V3 training is
+reduced GPU memory footprint is achieved. Notably, YOLOv3 training is
 much faster compared to other frameworks. Another example is Mask-RCNN
 (ResNet50), we managed to fit up to 4 images per GPU (Tesla V100 16GB) during
 multi-GPU training.

 # Transfer Learning
 
 Transfer learning aims at learning new knowledge from existing knowledge. For example, take pretrained model from ImageNet to initialize detection models, or take pretrained model from COCO dataset to initialize train detection models in PascalVOC dataset.
