| Feedforward networks have powerful approximation capabilities without the "explosion of parameters" problem faced by Fourier and polynomial expansions. This paper first introduces feedforward networks and describes their approximation capabilities, then we address several practical issues faced by applications of feedforward networks. First, we demonstrate networks can provide a reasonable estimate of a Bermudagrass hay fertilizer response function with the relatively sparse data often available from experiments. Second, we demonstrate that the estimated network with a practical number of hidden units provides reasonable flexibility. Third, we show how one can constrain feedforward networks to satisfy a priori information without losing their flexible... |

| Based on the facts of the peasant household and its labors, this paper analyses rational behavior strategy of the peasants and studies the microeconomic impact factors on the peasant behavior of employment with a discrete choice model. According to Econometric analysis, conclusions has been derived as follows: Firstly, the peasants behavior of employment is consistent with their wills to raise their income; Secondly, the peasants allocate labor resource in their peasant household on comparative advantages; Thirdly, non-agricultural job opportunity is a vital channel to release recessive unemployment and achieve sufficient employment of rural labors; Finally, peasants in different areas show slightly different tendency on obtaining non-agricultural jobs. |

Firstly, consumers feel unfair in their minds in the process of negotiation; secondly, the purchase decision rule tends to be simplified in the “lemon market” of agricultural products; thirdly, the consumers tend to follow the masses in the “lemon market” of agricultural products. The economics significance of the impact of “lemon dilemma” of agricultural products on consumers is analyzed. The causes of the impact are analyzed from two aspects the uncertainty of collecting the information of agricultural information and the uncertainty of... |
