Abstract

The purpose of this study is to set the rate of change between the market price of the next day and the previous day to be predicted as the predicted value, and the market price for each section is generated by dividing the stock price ranking of the next day to be predicted at regular intervals, which is different from the previous papers that predict the market price. We would like to propose a new time series data prediction method that predicts the market price change rate of the final next day through a model using the rate of change as the predicted value. The change in the performance of the model according to the degree of subdivision of the predicted value and the type of input data was analyzed.

본 논문의 연구 취지는 예측하고자 하는 다음 날과 이전 날의 시가 사이 변동률을 예측값으로 두고 시가를 예측하는 기존 논문들과는 다르게 예측하고자 하는 다음날의 주가 순위를 일정한 간격으로 분할하여 생성된 각 구간마다의 시가 변동률을 예측값으로 하는 모델을 통하여 최종적인 다음날의 시가 변동률을 예측하는 새로운 시계열 데이터 예측 방식을 제안하고자 한다. 예측값의 세분화 정도와 입력 데이터의 종류에 따른 모델의 성능 변화를 분석했으며 연구 결과 예측값의 세분화 정도에 따른 모델의 예측값과 실제값의 차이가 예측값의 세분화 개수가 3일 때 큰 폭으로 감소한다는 사실도 도출해 낼 수 있었다.
