Backpropagation Computation graph Mathematical expressions can be represented as directed acyclic graphs (DAGs), which permit the substitution of equivalent subexpressions. In the context of deep learning it is a sequence of calculations needed to compute the output of a neural network. We can show that logistic regression classifier can be seen as a single-layer neural network with labels 0 or 1.…
dbt with Apache Spark 1. What is this about In my previous work, I utilized a mix of the Scala Dataset API and Spark SQL for classification of transactions. While Datasets provide an excellent way to model data and its transformations in a type-safe manner, inexperienced teams often end up with a messy combination of Datasets and Spark SQL. As the project evolved, some parts began to reinvent…
