【Keras实例:Transformer时序分类】《Timeseries classification with a Transformer model》by Theodoros Ntakouris http://t.cn/A6fozz08 #机器学习#
from tensorflow.keras.layers import Dense, Conv1D, LSTM, Lambda, Reshape, RNN, LSTMCell import warnings warnings.filterwarnings('ignore') plt.rcParams['figure.figsize'] = (10, 7.5) plt.rcParams['axes.grid'] = False data = pd.read_csv('D:\交易\数据\\000300.XSHG_timeseries_open.csv',...
Tips: 有关learning rate warm up,在pytorch/tensorflow的版本的transformer都有自带的一个warmup_init.贴一段keras的warm up lr code: import numpy as np from tensorflow import keras from tensorflow.keras.models import Sequential fromtensorflow.keras.layers import Dense from tensorflow.keras import backend ...

问题定位和解决:keras-nightly~=2.5.0.dev也找不着,手动去pypi.org官网下载安装https://pypi.org/project/keras-nightly/#history,我下载了这个的whl:
This makes the Transformer model highly efficient for time series forecasting, offering a robust solution to the limitations of traditional models. In this study, the model is implemented using Python 3.9 and the Keras and TensorFlow libraries [4]. These libraries provide a high-level interface ...
