• Added the img_rand_resize_lower and img_rand_resize_upper parameters which specify that the variable-sized input image should be randomly resized.
• Added the global_grad_scale parameter which defines the constant C used to improve precision of back-propagation for float16 data storage.
• Added the default_cudnn_math_override parameter which sets the default cudnn_math_override value for every layer, if applicable.
• Added the store_blobs_in_old_format parameter which stores blobs in an old, less efficient BVLC-compatible format.
• Added the cudnn_math_override parameter which sets the default cudnnMathType_t value for all cuDNN-based computations in the current layer, if applicable, otherwise, it is ignored.
• Added the ELUParameter parameter stores parameters used by ELULayer.
• Added the lambda parameter which is used for Scaled Exponential Linear Unit (SELU™).
