Search before asking I have searched the YOLOv5 issues and discussions and found no similar questions. Question When I trained only several epochs using the Adam optimizer, losses became "nan". And this is not the case with SGD. How to s...
Using model.evaluate(X_train,Y_train) at the end of training, the train loss is the same as the vaidation loss, and both are nan. This is my custom loss function. def custom_loss(y_true, y_pred): import tensorflow as tf bce = tf.keras.losses.BinaryCrosse...

Lettuce (Lactuca sativa) is an important vegetable crop worldwide. Cultivated lettuce is believed to be domesticated from L. serriola; however, its origins and domestication history remain to be elucidated. Here, we sequenced a total of 445 Lactuca acces
One of the parameters that is not correlated with the thermal and hydrological terms is the “ageing term” or irreversible displacement, which is considered an indicator of the potential consolidation rate of the LUC. It has a small value because consolidation can sometimes take several years. ...
Caution To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the switch are within the current ratings for the wiring and breakers. AC Power The system is designed for connection to TN power systems. A TN power system is a power distribution sys...

Educators are seriously concerned about the high rate of dropouts among the doctor of philosophy candidates and the consequent loss of talent to a nation in need of Ph. D. s. Some have placed the dropouts loss as high as 50 percent. The extent of the loss was, however, largely a matter...
