[UFLDL] Python implementation of multilayer neural networks

Last week finished writing the code, but because did not notice the implementation of the Softmax related to the result is not correct, correct results can be corrected, with 200 pictures to iterate 200 times can be more than 90% of the correct rate, parameter settings have yet to be optimized, in addition to consider using multi-threaded acceleration, There is still a problem here (need to be modified, use caution).Please refer to the previous article http://blog.csdn.net/xuanyuansen/article/de

) { NSLog (@ "langarray=%@", object); }Here we can see there is no subscript, through the Nextobject method to traverse. The advantage of this method is to traverse the Nsdictionary and Nsset code is similar, inconvenient is the processing of the subscript will be inconvenient, in addition, the reverse traversal needs to use the Reverseobjectenumerator method.Objective-c developed to 2.0 with the Quick Traverse function, the code is as follows: For (ID object in Langarray) {

MongoDB Aggregation Operations

In MongoDB, there are two ways to calculate aggregations: Pipeline and MapReduce. Pipeline queries are faster than MapReduce, but the power of MapReduce is the ability to execute complex aggregation logic on multiple servers in parallel. MongoDB does not allow pipeline to consume too much system memory for a single aggregation operation, and if an aggregation operation consumes more than 20% of the memory, MongoDB stops the operation directly and outputs an error message to the client.One, the a
