Division. Python 3 does floating point division between two integers if you specify the division with two slashes (//). However, if we want Python 2 to do floating point division by default , we can use the handy function: >> from__future__ import division >>> 3/2 1.5 2. Printing. In Python 3, you have to […]

The target variables can be converted from the string labels to one-hot encoded vectors. A one-hot vector is filled with 1 at the index of the target class but with 0 everywhere else. For example, if the target classes are cat […]

It works on RS-485 serial communications and due to its differential signaling it reduces errors in communication. There are several versions of the MODBUS protocol. From MODBUS RTU to MODBUS ASCII and MODBUS TCP, they […]

Agents that must operate robustly in rapidly changing, unpredictable, or open environments, where there is a significant possibility that actions can fail are known as intelligent agents, or sometimes autonomous agents .Figure 4.1 […]

The Levenberg-Marquardt Back Propagation (LMBP) method is selected for training the ANN network to increase convergence speed, and to avoid long training times. The LMBP algorithm is based on numerical optimization techniques […]
