Can YouTube (e.g.) and the result of concatenation that I want is :merged.png. It is a nonsequential neural network, it connects all or part of the inputs directly to the output layer: This architecture makes it possible for the neural network to learn both deep patterns using the deep path and simple rules through the short path. Is it unusual for a host country to inform a foreign politician about sensitive topics to be avoid in their speech? Ensemble modeling is the process by which a machine learning model combines distinct base models to generate generalized predictions using a combination of the predictive power of each of its components. It's exactly the same procedure, just make sure that your model's output has the same shape as the other model's input. If you merge them, say by concatenating penultimate layer, then you'll have to retrain the last layer to output predictions for 1st + 2nd kind of objects and this may or may not work as good as it was before.
