What is the role of the bias in neural networks? [closed]
...g two dimensions to one dimension, as in reproducing the AND or the OR (or XOR) functions, you can think of a neuronal network as doing the following:
On the 2d plane mark all positions of input vectors. So, for boolean values, you’d want to mark (-1,-1), (1,1), (-1,1), (1,-1). What your ANN now ...
Bitwise operation and usage
...wise it's 0.
OR is 1 if one or both of its inputs are 1, otherwise it's 0.
XOR is 1 only if exactly one of its inputs are 1, otherwise it's 0.
NOT is 1 only if its input is 0, otherwise it's 0.
These can often be best shown as truth tables. Input possibilities are on the top and left, the resulta...
What is uintptr_t data type
...n that I just wrote to do bitwise exclusive or of 2 pointers to store in a XOR linked list so that we can traverse in both directions like a doubly linked list but without the penalty of storing 2 pointers in each node.

What integer hash function are good that accepts an integer hash key?
...r qualities, like
multiplication with an uneven integer
binary rotations
xorshift
To yield a hashing function with superior qualities, like demonstrated with PCG for random number generation.
This is in fact also the recipe rrxmrrxmsx_0 and murmur hash are using, knowingly or unknowingly.

For i = 0, why is (i += i++) equal to 0?
...
Disassembly of the running code:
int i = 0;
xor edx, edx
mov dword ptr i, edx // set i = 0
i += i++;
mov eax, dword ptr i // set eax = i (=0)
mov dword ptr tempVar1, eax // set tempVar1 = eax (=0)
mov eax...

Using the field of an object as a generic Dictionary key
...You might want to start with the Equals-Method and then (in GetHashCode()) xor the hash code of every member you compare in Equals.
