Bulk Arps Curve Fitting on GPU

This article proposes a method for significantly faster Arps decline curve fitting on large datasets using TensorFlow on GPUs. It tackles the limitations of traditional approaches, which rely on iterative curve fitting, like SciPy's curve_fit, applied to each data point one at a time. By leveraging TensorFlow's parallel processing

Recording Data History Between The Application Level and SQL Server Temporal Tables (part 1)

Imagine logging into your application's database and finding a change in a data record that just doesn’t make any sense. You trace the application code, check for any bugs, sit with the users, try reproducing the change and all of this doesn't get you anywhere! Wouldn't it give you

Inductive Clustering For Lower Dimension Input Vectors

IntroductionWe often need to expand or generalize the output of clustering algorithms for unseen data points in training without recomputing the clustering. Some clustering algorithms support this by nature, which is called Inductive Clustering. This article will discuss extending the non-inductive clustering algorithms to classify new instances and classify data
