" SQL Project on Zomato Analytics "

🧵
#SQL is the most important tool, a data analyst uses to manipulate and gain insights from the data. In this #project, we will try to process, and analyze the data

SQL is the “meat and potatoes” of #dataanalysis

It’s semantically easy to understand and learn.

Day 11 of #100dayswithMachineLearning

Topic : Tensor in Machine Learning

🧵
A tensor is a container which can house data in N #dimensions. Often and erroneously used interchangeably with the matrix (which is specifically a 2-dimensional #tensor), tensors are generalizations of #matrices to N-dimensional space

Tensor notation is much like matrix notation Image
Tensors are more than simply a data container, however. Aside from holding numeric #data, tensors also include descriptions of the valid linear #transformations between tensors. Examples - include the cross product and the dot product.
