Welcome to the Keras time series tutorial! This guide will walk you through building and training models for time series prediction using TensorFlow Keras. Let's dive in!

📌 What is Time Series Analysis?

Time series analysis involves predicting future values based on historical data. Common applications include:

  • Stock price forecasting
  • Weather prediction
  • Anomaly detection in system metrics
  • Sales trend analysis

Keras simplifies this process with its intuitive API and powerful tools for sequence modeling.

🧩 Step-by-Step Guide

  1. Prepare Data

    • Load your dataset (e.g., CSV, JSON)
    • Split into training and testing sets
    • Normalize values using MinMaxScaler

  2. Build Model
    Use SimpleRNN, LSTM, or GRU layers. Example:

    model = Sequential([
    SimpleRNN(50, input_shape=(X_train.shape[1], 1)),
    Dense(1)
])

  3. Train Model
    Compile with Adam optimizer and mse loss:

    model.compile(optimizer='adam', loss='mse')
model.fit(X_train, y_train, epochs=20, validation_split=0.2)

  4. Evaluate & Predict

    • Use model.evaluate() for metrics
    • Generate predictions with model.predict()

📊 Visualize Results
