1. Why add pooling (pooling) to the convolutional networkIf you only use convolutional operations to reduce the size of the feature map, you will lose a lot of information. So think of a way to reduce the volume of stride, leaving most of the information, through pooling to reduce the size of feature map.Advantages of pooling:1. Pooled operation does not increase parameters2. Experimental results show that the model with pooling is more accurateDisadvantages of pooling:1. Because the stride of t

Kafka in versions prior to 0.8, the high availablity mechanism was not provided, and once one or more broker outages, all partition on the outage were unable to continue serving. If the broker can never recover, or a disk fails, the data on it will be lost.
