i want allow checkbox-filtering, such when particular checkbox 'checked', page show items corresponding checkbox property. example) want products 'new', check box new products. how can create kind of filter in bigcommerce? have tried url-api filter, granted didnt expect much, have @ least tried it. i hoping way 'hide' other products if dont fall under checkbox's property. you can write javascript you, main thing you'd need here somehow differentiate between product types. example: designates product 'new' vs 'old'? i happy write script react users interaction checkboxes, need html here products in order have our javascript recognize them. can update question html examples of products or items want hide/show based on user interaction checkbox selector?

i have problem concept of validation nn. suppose have 100 set of input variables (for example 8 input, x1,...,x8) , want predict 1 target(y). have 2 ways use nn: 1- use 70 set of data training nn , use trained nn predict other 30 sets of target validation , plot output vs target 30 sets validation plot. 2- use 100 sets of data training nn , divide outputs 2 part (70% , 30%). plot 70% of outputs vs corresponding targets training plot. plot other 30% outputs vs corresponding targets validation plot which 1 correct?? also, difference between checking nn new data set , validation data set?? thanks you cannot use data validation, if has been used training, because trained nn "know" validation examples. result of such validation biased. sure use first way.

is more efficient use: if ( a+b+c > 0) or if ( a>0 || b>0|| c>0) or there better way either of these? these 2 expressions not equivalent: first expression false a=1, b=0, c=-1 , while second true . the first expression require 2 additions, comparison zero, , branch, while second expression require 3 comparisons 0 , 3 branches, because || operator short-circuiting. in end, difference going undetectably small. the case when second expression win when a , b , c represent expensive computations: if (expensivecomputationa() > 0 || expensivecomputationb() > 0 || expensivecomputationc() > 0) { ... } since computation above stop after first success, resultant code faster result of short-circuiting expensive branches.
