5 docs tagged with "initialization"

Initialize arrays and simple structs using brace-enclosed lists without constructors. Concise syntax for multiple members.

Object created without explicit initializer. Behavior depends on type and storage duration. Dangerous for fundamental types in local scope.

C++11 brace initialization {} - one syntax for all types. Consistent, safe (prevents narrowing), solves gotchas.

Explicitly request zero-initialization for fundamentals, default construction for classes. Safer than default initialization.

Before the first gradient is ever computed, a choice has already been made that decides whether training has any chance of working: how the weights start. Get it wrong and the signal either dies (shrinks to zero within a few layers) or explodes (grows without bound) before a single useful gradient update happens.
