Prepare a chronological dataset
Build a dataset with stable timestamps, impute or flag missing values, create lag and calendar features and avoid any future leakage into features.
Apply attention to time series. Assess forecast accuracy.
Attention mechanisms let models selectively weight past timesteps when making forecasts, which can improve modelling of long-range dependencies and irregular temporal patterns. Practical issues include window selection, memory cost for long sequences, seasonality and calendar effects, walk‑forward validation and drift monitoring.

Attention mechanisms let models selectively weight past timesteps when making forecasts, which can improve modelling of long-range dependencies and irregular temporal patterns. Practical issues include window selection, memory cost for long sequences, seasonality and calendar effects, walk‑forward validation and drift monitoring.
A proposed application: short- to medium-horizon revenue or demand forecasting for retail planners, where attention can help surface which past events most influence a prediction. Any operational use should keep a human planner in the loop for anomalous or high-impact decisions.
Build a dataset with stable timestamps, impute or flag missing values, create lag and calendar features and avoid any future leakage into features.
Split data into successive training and test windows so each fold simulates forecasting into the future and prevents information leakage.
Implement a lightweight Transformer or attention-based RNN that accepts sliding windows of past values and outputs forecasts with uncertainty estimates.
Compute MAE/RMSE and prediction‑interval coverage, inspect attention weights for plausibility and add drift and input‑quality alerts.
The supplied starter generates a synthetic daily series with trend, seasonality and noise, creates lag and rolling-mean features, splits the last 30 days for test, fits a RandomForestRegressor on those features, then prints MAE and a small forecast table. It does not implement any attention mechanism or Transformer-style model.
feature_cols = ["lag_1", "lag_7", "lag_14", "rolling_7"]
train = series.iloc[:-30]
test = series.iloc[-30:]
model = RandomForestRegressor(n_estimators=300, random_state=42)
model.fit(train[feature_cols], train["value"])
forecast = model.predict(test[feature_cols])
print(PROJECT_NAME)
print("MAE:", round(mean_absolute_error(test["value"], forecast), 3))The starter is a feature-based RandomForest baseline on synthetic data and contains no attention layers, no sequence-to-sequence modelling and no walk‑forward cross‑validation beyond a single holdout. Results on the toy series do not validate attention techniques.
A proposed extension: replace the RandomForest with a compact Transformer encoder or temporal attention module that consumes sliding windows of raw values and outputs probabilistic forecasts, then compare with the baseline using walk‑forward folds.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
