Question

After the success of CNNs in IVSRC 2012 (Krizhevsky et al. (2012)), initialization with Gaussian noise with mean equal to zero and standard deviation set to 0.01 and adding bias equal to one for some layers become very popular.

Why it is not possible to train very deep networks from scratch with this initialization?

GENERALIDADES DEL DERECHO ECONÓMICO El Derecho Económico emerge al final del siglo pasado como un producto de la crisis y de la globalización. El Estado como único centro irradiador de Normas Jurídicas, tanto Públicas como Privadas, así como la discriminación entre Nacionales y Extranjeros; Inversión Nacional vs. Inversión Extranjera, son algunas de las problemáticas a las que se enfrentó, no fáciles de resolver, bajo el derecho tradicional. Así, el Derecho Económico cambia de un perfil Público-Social a un derecho de la promoción y des-regulación, en donde las leyes reemplazan a acuerdos y decretos. Se intenta pasar de un Derecho Económico Discrecional a un Derecho Económico Mandatario, al cual se le adicionan obligaciones internacionales no susceptibles de regateo y negociación.

^^^^ local variables are declared and defined within "locals" blocks in the *.tf files, and is just a map of values, e.g.
