Understanding Time Series Data

Time series data is a sequence of data points collected over time. It can be used to analyze trends, patterns, and make predictions. For example, stock prices, weather data, and sales data are all examples of time series data.

Time Series Data Example

Setting Up TensorFlow

Before you start, make sure you have TensorFlow installed. You can install TensorFlow using pip:

pip install tensorflow

Building a Model

To build a time series prediction model, we will use TensorFlow's Keras API. Here's a basic structure of the model:

import tensorflow as tf
from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import LSTM, Dense

# Define the model
model = Sequential()
model.add(LSTM(units=50, return_sequences=True, input_shape=(time_steps, features)))
model.add(LSTM(units=50))
model.add(Dense(units=1))

# Compile the model
model.compile(optimizer='adam', loss='mean_squared_error')

Training and Evaluating the Model

After building the model, you need to train it using your time series data. Here's an example:

# Train the model
model.fit(x_train, y_train, epochs=100, batch_size=32)

# Evaluate the model
loss = model.evaluate(x_test, y_test)
print(f"Test Loss: {loss}")
