Linear discriminant analysis (Linear?) Discriminant? Analysis,? LDA), sometimes also called Fisher linear discriminant (Fisher?) Linear? DISCRIMINANT?,FLD),? Is this algorithm Ronald? Fisher, invented in the 1936, is a classic algorithm for pattern recognition. In the 1996, the field of pattern recognition and artificial intelligence was introduced by Belhumeur.The basic idea is to project the high-dimensional pattern sample to the best discriminant vector space, in order to achieve the effect o

Valueerror:negative dimension size caused by subtracting 3 from 1 The reason for this error is the problem with the picture channel.That is, "channels_last" and "Channels_first" data format problems.Input_shape= (3,150, 150) is the Theano, and TensorFlow needs to write: (150,150,3). You can also set different back ends to adjust: From Keras Import backend as K k.set_image_dim_ordering (' th ') from Keras Import backend as K

Array Design idea: In VB, the number of elder sister is 60, so we deal with the problem by error capture, where we use the UBound function Public Function Arrayrange (Marray as Variant) as Integer Dim I as Integer Dim Ret as Integer Dim ERRF as Boolean ERRF = False On Error GoTo Errhandle ' To determine whether an incoming argument is an array If not IsArray (Marray) Then Arrayrange =-1 Exit Function End If ' VB in the largest array of 60 For i = 1 to 60 ' Using the UBound function to determin

ObjectiveI often see a lot of programmers, The_silver_searcher in code Search using ACK, and even AG (a), and I work 95% are using grep, the rest is AG. I think it's necessary to have a chat about this topic. I used to be an operational dimension, and I also wanted to find the best and quickest tool to use in every aspect of my work. But I'm curious as to why AG and ACK are not built into Linux distributions. The built-in is always grep. My original u

Method One: Use the array map () method, which runs the given function for each item in an array, and returns a list of the results of each function call.Let arr = [1, [2, [[3,4],5],6]];function Onedimensionalarray (arr) { "). Split (','// Convert the array to a string and then comma-delimited to array let arr2 = Arr1.map (function (x ) {return number (x); }); return arr2;} Console.log (Onedimensionalarray (arr));Law two: Using apply combined with concat,
