Ask HN: How do you collect data for training your ML models?

If you&#x27;re building and ML models, what is your process for collecting data?<p>For Example:<p>1&#x2F; Do you have dedicated hardware pipelines that send images&#x2F;video&#x2F;audio&#x2F;text to a database in real-time or do you collect data in batches and then offload later?<p>2&#x2F; Do you collect mobile sensor data (iOS&#x2F;Android) or do you have custom hardware?<p>3&#x2F; Do you rely on open source data sets like ImageNet &#x2F; Google Open Images &#x2F; Kaggle &#x2F; Fishnet or are you collecting images for a use case that those data sets don&#x27;t solve?
