Local minima is also a controversial issue. A theoretical proof (Hornik 1989) under strong assumptions with the conclusion that the neural network has no local minima is rejected by experimentation on the real model with finite sample set. In this article we will analyze the problem in a different direction with conclusive conclusion: The neural … Đọc tiếp Neural network: Local minima
Cybersecurity: Unpredictable Random Number Generator
Random Number Generator is an important factor of security activity to create cryptographic keys and passwords. We already know that the rand() function is a simple pseudo-random number generator. It returns a pseudo-random integer in the range 0 to RAND_MAX, ie, the mathematical range [0, RAND_MAX]. You can use rand() to define your own function … Đọc tiếp Cybersecurity: Unpredictable Random Number Generator
Building a fault-tolerant firewall system with virtual machines: Kernel patch due to loss of helper
The issue of a conntrack injection from user space lost helper that was mentioned in the expectation post. That's one way to fix it. A patch has been added to the Linux kernel as follows: [ Upstream commit d1ca60efc53d665cf89ed847a14a510a81770b81 ]When userspace, e.g. conntrackd, inserts an entry with a specified helper,its possible that the helper is … Đọc tiếp Building a fault-tolerant firewall system with virtual machines: Kernel patch due to loss of helper
