A naive bayes classifier can yield similar results as a neural network. Learn how to implement one in plain Cypher: youtu.be/YbHbsaJhhKM

To materialize a physical plan, #ApacheSpark schedules tasks on the workers. In fact, the workers have one single functionality: to execute a task. Let's explore how a physical plan is transformed into schedulable tasks. youtu.be/-iF7_tDtc3k

Naive Bayes classification is naive because it assumes independence of features. The maths are very simple. However, it works astonishingly well for our recommendation engine. youtu.be/YbHbsaJhhKM

How to build a recommendation engine in #neo4j. ⏫ Naive Bayes classification 🚀 Performs as good as a deep neural network ✅ Just a handful lines of code youtu.be/YbHbsaJhhKM

What's the fundamental principle enabling Apache Spark to parallelize workload? I'm creating a video series on the internals of Spark. The first video is a deep dive into Spark's most profound principle: MapReduce. youtu.be/BKecoKKs91A

A sampling strategy enables us to find the structural contexts of two nodes in a graph. We can use these contexts to find their similarity - for example using the Jaccard set similarity metric. node2vec uses contexts to map nodes to vectors. youtu.be/pS_POUVFXvk

Consequently, Spark core’s optimization strategy is limited to pipeline narrow transformations into stages. towardsdatascience.com/the-bigger-pic…
