Although artiicial neural networks are employed in an ever growing variety of applications , their inner workings are still viewed as a black box, which is due to the complexity of the non-linear dynamics that govern neural network learning. The key parameters in this learning process are the so called interconnection strengths or weights of the connections… (More)
Phytochemical study of the aerial parts of INULA VISCOSA resulted in the isolation of sixteen flavonoids. One of them, 3- O-acetylpadmatin [(2 R,3 R)-3-acetoxy-5,3',4'-trihydroxy-7-methoxyflavanone], was isolated for the first time as a natural compound. Ferulic aldehyde, 2-methylphloroacetophenone, inuviscolide and 2-deacetoxyxanthinin were also isolated.
