From Machine Learning to Machine Unlearning

After all, the term Machine Learning was coined based on the way the human (or animal) brain learns, meaning that somehow, machines could also benefit from a similar kind of learning.

Why is Data Missing from the Balance Sheet?

I have been asked many times is data a business asset?. Why is it that an intangible asset like data is not in the company’s balance sheet - a statement of the assets, liabilities, and capital of a business at a particular point in time? Technically, an intangible asset is a non-physical asset that has a multi-period useful life. Examples of intangible business assets are patents, copyrights, customer lists, trademarks, brand names, logo, and data. While data in the recent years…

Supply chain bottlenecks, big data and security

Enterprise supply chains have seen transformative changes and exponential growth, almost to a breaking point, over the past decade. This disruption is driven by multiple factors, including the growth of the supply chain itself to include potentially thousands of global partners, often with their own agendas, technologies, security protocols and strategic plans that may not intersect.

Common supply chain bottlenecks may include poor forecast accuracy levels, an inability to make full…
