Welcome to the TensorFlow time series forecasting tutorial! This guide will walk you through building and training models to predict future data points using historical sequences. 🧠
Key Concepts
- Time series data is sequential data where each observation is dependent on previous ones (e.g., stock prices, weather trends).
- TensorFlow provides tools like
tf.keras
andtf.data
for efficient model development. 🛠️ - Common tasks include data preprocessing, model selection, and evaluation. 📊
Step-by-Step Guide
Data Preparation
Split your dataset into training and testing sets. Example: Use `tf.data.Dataset` to load and split data.Model Building
Choose architectures like LSTM or Transformer. Code snippet: ```python model = tf.keras.Sequential([ tf.keras.layers.LSTM(50, return_sequences=True), tf.keras.layers.Dense(1) ]) ```Training Process
Compile the model with an optimizer and loss function. Example: ```python model.compile(optimizer='adam', loss='mean_squared_error') ```Forecasting Example
Predict future values using the trained model. Visualize results with `matplotlib` or `plotly`.Evaluation Metrics
Calculate accuracy using MAE or RMSE. Formula: $$ \text{RMSE} = \sqrt{\frac{1}{n} \sum_{i=1}^{n} (y_i - \hat{y}_i)^2} $$
