Huber loss is a loss function that is used to solve regression problems. This function is a combination of the mean squared error (MSE) and mean absolute error (MAE). Huber...
Most countries use the 24 hour clock, but there are countries that use the 12 hour clock. Programming languages provides various methods to convert 24 hour time to 12 hour...
Working with dates sometimes we need to perform various arithmetic operations. Programming languages provides methods to calculate number of days between two dates. A table includes a links to posts...
SHA3-256 is a cryptographic hash function that accepts a string of any length and returns a 256-bit fixed-length digest value, commonly represented as a sequence of 64 hexadecimal digits. SHA3-256...
Log-cosh loss is a loss function that is used to solve regression problems. Log-cosh is calculated as the average logarithm of the hyperbolic cosine of the differences between the predicted...
Binary cross-entropy (BCE) is a loss function that is used to solve binary classification problems (when there are only two classes). BCE is the measure of how far away from...
TensorBoard is a tool which allows visualizing training metrics (e.g. loss and accuracy), model graph, activation histograms, profiling results, etc.
This tutorial demonstrates how to visualize training metrics using TensorBoard...
When working with ESP8266 we may need to be able to discover surrounding Wi-Fi networks.
This tutorial provides example how to scan the available Wi-Fi networks using ESP8266 NodeMCU development...
TensorFlow 2 provides the RemoteMonitor callback which allows to send epochs results during training to a server. A server can save results to a file, database table or perform other...
