Infinitely scalable machine learning with Amazon SageMaker

All Things Distributed

For example, training on more data means more accurate models. Last re:Invent, to make the problem of authoring, training, and hosting ML models easier, faster, and more reliable, we launched Amazon SageMaker. " To make things even more challenging, a system that can handle a single large training job is not nearly good enough if training jobs are slow or expensive. Machine learning models are usually trained tens or hundreds of times.

Our Once and Future Wisdom: Re-acquiring Lost Institutional Knowledge

The Agile Manager

It took a lot of challenging the "why" on those specific portions of the value stream before they understood how a simple shared database would eliminate lots of no-value-added inventory control steps. More modestly, we can simply license technology to replace major portions of legacy systems, and train or hire experts in that technology. Last month we looked at the loss of institutional memory and the reasons for it. This month, we look at our options for re-acquiring it.
