window_size and batch_size in config.yaml about telemanom

[khundman]

I assume that means that one minute contains 30 values (so 1 value per 2 seconds). Is that correct?

No, the processed SMAP telemetry used in this experiment contains 1 value per minute per channel. Once 70 minutes pass, this data comes down from the spacecraft in a batch (approx. 70 values per channel).

Could you explain the reason for h to be divided into 2 seperate parameters?

These two numbers represent different aspects of the problem. As described above, the batch_size (70) represents the chunks of data we receive in each batch. This is not a streaming scenario, so we are restricted to processing these batches as they arrive. For different problems this value would be set to whatever the batch size/cadence is. The window_size is a tuneable parameter that balances the tradeoff between 1) providing a lot of historical context to the algorithm for evaluating the severity of an anomaly (larger window) and 2) computational efficiency and memory efficiency (larger windows are higher cost).
