Abstract:    Learning in neural networks suffers from the fixed structure of the network with a given number of layers and neurons when gather information for training. In this talk, a dynamic neural network structure via Stacked Broad Learning Systems (BLS) will be discussed. The BLS has been proved to be effective and efficient lately. The proposed dynamic model is a novel incremental stacking of BLS. This invariant inherits the efficiency and effectiveness of BLS that the structure and weights of lower layers of BLS are fixed when the new blocks are added. The modified incremental stacking algorithm only computes the connection weights within the BLS block while the connecting weights of the lower stacks remains fixed, making the learning process very efficient. In addition, taking the advantages of BLS that can accumulate and reuse the learned knowledge, applications of BLS, Federated Broad Learning, in an open environment will be discussed. Federated Broad Learning supports learning from streaming data continuously, so it can adapt to the environment changes and provide better real-time performance.
