Abstract

In this paper, we predicts the estimated price using the DNBP (Deep learning Network to predict Budget Price) model with bidding data obtained from the bidding websites, ElecNet and OK EMS. We use the DNBP model to predict four lottery preliminary price, calculate their arithmetic mean, and then estimate the expected budget price ratio. We evaluate the model's performance by comparing it with the actual expected budget price ratio. We train the DNBP model by removing some of the 15 input nodes. The prediction results showed the lowest RMSE of 0.75788% when the model had 6 input nodes (a, g, h, i, j, k).

본 논문은 입찰사이트 전기넷과 OK EMS에서 입수한 입찰데이터로 DNBP(Deep learning Network to predict Budget Price) 모델을 통해 예정가격을 예측한다. 우리는 DNBP 모델을 활용하여 4개의 추첨예비가격을 예측을 하고, 이를 산술평균 한 뒤 예정가격 사정률을 계산하여, 실제 예정가격 사정률과 비교하여 모델의 성능을 평가한다. DNBP의 15개의 입력노드 중 일부 입력노드를 제거하여 모델을 학습시켰다. 예측 결과 예측 결과 입력노드가 6개(a, g, h, i, j, k) 일 때 DNBP의 RMSE가 0.75788% 로 가장 낮았다.
