YOLACT++ used in the current research was implemented on Python3, Pytorch 10.0.1 and TorchVision. TorchVision is an open library for computer vision used with PyTorch. The model based on CNN is rarely trained from scratch because it requires a relatively large dataset. Therefore, the transfer learning technique was applied to the model trained with a batch size of eight on one GUP using ImageNet pretrained weights [37 (link)]. The model was trained with the stochastic gradient descent method [38 ,39 (link),40 ] for 800,000 iterations starting at an initial learning rate of 0.001, with a momentum of 0.9 and weight decay of 0.0005, and all data augmentations used in the single-shot detector (SSD) [32 (link)] except up-side down and left/right flip were applied. The training process was conducted using a 3.0 GHz Intel Core i9-9980XE CPU, 62.5 GB RAM DDR4, GPU NVIDIA TITAN RTX 24 GB on an Ubuntu 20.04 operating system.

Deep Neural Network Classifier Protocol
We chose tf.contrib.learn.DNNClassifier for model construction. For the hyperparameters of our model, we set the dropout rate at 0.15, we chose the Adam optimizer, and we fixed the learning rate at 1e-5. The activation function was leaky_relu and the number of layers was 4. The numbers of neurons of the layers were 512, 256, 128, and 16, respectively (
In order to obtain measurements for the performance of our model, accuracy was calculated using the predicted values from the training set and the test set; then, receiver operating characteristic curves and the area under the curve (AUC) were obtained by the roc-curve function in the scikit-learn package.

All proposed approaches were implemented using the Python 3.7 library, such as PyTorch 1.5, Scikit-learn, and SHAP, on an NVIDIA TITAN RTX 24 GB × 2. The source code is available on GitHub [27 ].
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
