1. Why symmetric key cryptography alone cannot resolve Internet security issue?
Symmetric-key algorithms are algorithms for cryptography that use the same cryptographic keys
for both encryption of plaintext and decryption of cipher text. The keys may be i

Chapter 3 Output: Knowledge Representation
It is important to know how structural patterns produced by machine learning techniques can be
expressed before learning how the techniques work. There are many different ways for
describing the patterns each one
Chapter 5 Credibility: Evaluating Whats Been Learned
Evaluation is critical in data mining and machine learning. In order to evaluate different
algorithms, we have to take systematic approaches to compare one method to others.
