In the last tutorial, we introduced the concept of linear regression with Keras and how to build a Linear Regression problem usingTensorflow’sestimator API. In that tutorial, we neglected a step which for real-life problems is very vital. Building any machine learning model whatsoever would requ...
In a neural network, the activation function is responsible for transforming the summed weighted input from the node into the activation of the node or output for that input. The rectified linear activation function or ReLU for short is a piecewise linear function that will output the input dir...
The models are implemented with Keras [71] in Python 3. The inputs for the ARMAX model directly follow from the physical structure described in Section 3. They comprise autoregressive terms for the room temperature,7 moving average terms for neighbouring zones, the ambient temperature, the one-...
