WebAug 30, 2024 · CNNs with 2-D convolutions are the “typical” kind of neural network used in deep learning, which normally are used on images (e.g. ImageNet, object detection, … Gramian angular field (GAF) GAF is a novel time-series encoding method proposed by Wang and Oates (Wang and Oates 2015), which represents time series data in a polar coordinate system and uses various operations to convert these angles into symmetry matrix. Gramian Angular Summation Field (GASF) … See more Considering real-world data lacking and complexity, it starts with simulation data to ensure GAF-CNN model work and progress feature … See more We select eight of the most classic candlestick patterns based on a classic candlestick patterns textbook, The Major Candlesticks Signals, as our training target. The eight candlestick patterns we chose are Morning … See more According to the previous section, the candlestick patterns cannot judge from a single value such as closing or opening price. Therefore, we need to combine opening, high, low, and closing prices (OHLC) and make … See more We propose a two-step approach and call it the GAF-CNN model. The first set is the Gramian Angular Summation Field (GASF) time-series encoding, and the second step is the Convolutional Neural Networks (CNN) … See more
