DeepAR algorithm highlights The DeepAR forecasting algorithm can provide better forecast accuracies compared to classical forecasting techniques such as Autoregressive Integrated Moving Average (ARIMA) or Exponential Smoothing (ES), both of which are implemented in many open-s...
With data wrangling complete, the ST-ELF model is now ready for training. To train the model, we use Amazon Forecast (in Module 2). Using Amazon Forecast requires the import of training data, creation of a predictor (the ST-ELF model in this case), and creation of a forecast using the...
DeepAR+- Amazon proprietary algorithm, works best with large datasets of data with similar underlying patterns, and can identify seasonal effects and leverage related data. CNNQR- Amazon proprietary algorithm, works best with large datasets of data with similar underlying patterns, and can identify se...

We use reanalysis data from the European Centre for Medium-Range Weather Forecasts (ECMWF) Reanalysis v5 (ERA5) with horizontal resolution of 25 km39. The ERA5 reanalysis uses the ECMWF Integrated Forecast System (IFS) and is the highest resolution and most widely used global reanalysis dataset...

MODIS relies on an algorithm to detect fires based on the strong mid-infrared signal emitted by fires. The algorithm is not perfect and can mistake very bright or reflective surfaces as fires [55]. The MODIS dataset provides a confidence value for each hot pixel detected that ranges from 0 ...
A keyword spotter is a functional component or algorithm that evaluates an audio signal to detect the presence a predefined word or expression in the audio signal. Rather than producing a transcription of the words of the speech, a keyword spotter generates a true/false output to indicate ...
