Can you help me about cell death?
I dont understand much about what is cell death in brain, and how spatial pooler can implement a cell death. as i understand, if all connections in receptive field of a column are connected, it means that this column is death.
please correct me if i am wrong.
No, I don’t think that this is true. It does mean that the cell will respond to any pattern that turns on the bits in it’s receptive field. This would be a highly unusual learned pattern and the “sparse activation” part of HTM theory should prevent this from happening.
One of the spatial pooler papers showed tolerance to simulated cell death. I this is what @Rodi is referring to. It is not a part of the Spatial Pooling process, it is just something that SP handles well.
