Use dropout regularization (classify train only) Mask downsample ratio (segment train only) Masks should overlap during training (segment train only) (int or list, optional) freeze first n layers, or freeze list of layer indices during training Profile ONNX and TensorRT speeds during training for loggers (int) disable mosaic augmentation for final epochs (0 to disable)Īutomatic Mixed Precision (AMP) training, choices=ĭataset fraction to train on (default is 1.0, all images in train set) Rectangular training with each batch collated for minimum padding (bool or str) whether to use a pretrained model (bool) or a model to load weights from (str) Number of worker threads for data loading (per RANK if DDP) cuda device=0 or device=0,1,2,3 or device=cpu Use cache for data loadingĭevice to run on, i.e. Save checkpoint every x epochs (disabled if < 1) Save train checkpoints and predict results Number of images per batch (-1 for AutoBatch) Number of hours to train for, overrides epochs if suppliedĮpochs to wait for no observable improvement for early stopping of training Careful tuning and experimentation with these settings are crucial for optimizing performance. Additionally, the choice of optimizer, loss function, and training dataset composition can impact the training process. Key training settings include batch size, learning rate, momentum, and weight decay. These settings influence the model's performance, speed, and accuracy. The training settings for YOLO models encompass various hyperparameters and configurations used during the training process. train, val, predict, export, track, benchmark Track: For tracking objects in real-time using a YOLOv8 model.īenchmark: For benchmarking YOLOv8 exports (ONNX, TensorRT, etc.) speed and accuracy. Predict: For making predictions using a trained YOLOv8 model on new images or videos.Įxport: For exporting a YOLOv8 model to a format that can be used for deployment. Val: For validating a YOLOv8 model after it has been trained. Train: For training a YOLOv8 model on a custom dataset. YOLO models can be used in different modes depending on the specific problem you are trying to solve. Pose: For identifying objects and estimating their keypoints in an image or video. Segment: For dividing an image or video into regions or pixels that correspond to different objects or classes.Ĭlassify: For predicting the class label of an input image. These tasks differ in the type of output they produce and the specific problem they are designed to solve.ĭetect: For identifying and localizing objects or regions of interest in an image or video. YOLO models can be used for a variety of tasks, including detection, segmentation, classification and pose. ARGS (optional) are arg=value pairs like imgsz=640 that override defaults.ĭefault ARG values are defined on this page from the cfg/defaults.yaml file.MODE (required) is one of ( train, val, predict, export, track).TASK (optional) is one of ( detect, segment, classify, pose).Teacher: That’s right, to find half of a number, we divide by 2.From ultralytics import YOLO # Load a YOLOv8 model from a pre-trained weights file model = YOLO ( 'yolov8n.pt' ) # Run MODE mode using the custom arguments ARGS (guess TASK) model.Let’s look at how we might teach estimating a sum with benchmarks, using the same fractions we compared: 5/8 + 2/5ġ) Before adding, ask students to estimate the answer by changing each fraction to a benchmark of 0, ½, or 1.Ģ) Estimating 5/8 prompts the question ‘how many 8ths would be in exactly half?’ (bulleted items are a sample discussion between teacher and student) Fraction Benchmarks to Estimate Fraction Addition When it comes to using fraction benchmarks in 5th and 6th grades and beyond, we might not be using them as much to teach comparing fractions but we can teach using benchmarks (and finding half) in the context of estimating answers for adding and subtracting fractions (and eventually for multiplying and dividing). Have you found this too? That may be something for another post! Using Fraction Benchmarks in 5th & 6th Grades I have found, however, that some students don’t know how to find half of a number and even if they do know, they have trouble with half of an odd number. So, if 5/8 is more than half and 2/5 is less than half, that means 5/8 must be greater than 2/5.2.5/5 would be exactly half, and 2/5 is less than that.Hmm, 4/8 is half (benchmark) and 5/8 is more than that.When students are asked to compare fractions like 5/8 and 2/5, for example, the standard would like them to be able to look at 5/8 and think: Let’s look at the 4th grade concept of using benchmarks to compare fractions. 4th Grade: Using Fraction Benchmarks to Compare
