What is the difference between feed-forward and feedback systems in data mining?
Feed-forward network
Feed-forward neural networks enable signals to travel one method only, from input to output. There is no feedback (loops) i.e., the output of any layer does not affect that same layer. Feed-forward networks influence to be easy networks that relate inputs with outputs. They are extensively used in pattern recognition. This type of organization is also defined as bottom-up or top-down.

This type of organization is also defined as bottom-up or top-down.
The weighted outputs of these units are fed simultaneously to the second layer of neurons like units known as the hidden layer. The hidden layer is weighted output which can be input to another hidden layer and so on. The number of hidden layers is arbitrary and usually, one is used.
The weighted outputs of the last hidden layer are inputs to units making up the output layer, which emits the network's prediction for given samples. The units in the hidden layers and output layer are defined as neurodes, because of their symbolic biological basis or as output units. Multilayer feed-forward networks of linear threshold functions given through hidden units can closely approximate any function.
Feedback Networks
Feedback networks can have signals traveling in both areas by learning loops on the web. Feedback networks are very dynamic and can get extremely complex. Feedback networks are dynamic, their states are changing continuously until they reach an equilibrium point.
The remains at the equilibrium point until the input changes and a new equilibrium needs to be found. Feedback architectures are also defined as interactive or recurrent, although the term can indicate feedback connections in individual-layer organizations.
When a large database is involved in increasing the accuracy of deep neural network algorithms, a model of data production and artificial intelligence learning for behavioral research is essential. In general, clinical data are used when the user's disease information is included. At this time, if the clinical data are inaccurate, the results of the predictions are incorrect.

Moreover, if the information about the user's behavior and activity, other than the clinical data is not reflected, time-series data according to the user’s situation which changes over time, must be used as an input value to accurately predict the results.
The feedback model for the deep neural network algorithm includes an original feedback model and a secondary feedback model that restate the result.
