Today, organizations can use different types of data warehouses – from small-size information banks (data marts and repositories of unstructured data or data lakes) to classical big-volume relational databases, where information is in the form of easy-to-access tables. Yet, whatever model of im...
Now that we have our base model, we need a good dataset to train on. Themnist-fashiondataset is used often in this space as it’s MIT licensed,openly available, and has a significant number of data (60k images in total). Like any good data scientist, we need to understand our data ...
We analyse how to deal with the uncertainty before solving a stochastic optimization problem and we apply it to a forestry management problem. In particular, we start from historical data to build a stochastic process for wood prices and for bounds on its demand. Then, we generate scenario ...
