Under the background of "1 + X" policy of big data, this paper improves the BP neural network evaluation model, designs the local undergraduate innovation and entrepreneurship education quality evaluation platform, and selects four undergraduate universities as samples for data collection and analysis. According to this principle, the evaluation range of the standard platform designed in this paper is Y1 = (0.845, 0.158, 0.032, 0.007), the maximum element is 0.845, and the corresponding rating level is "very good". Therefore, it can be seen that the quality evaluation platform designed in this paper is similar to the standard platform the real results are similar.
