Pandas offers a variety of tools & methods to optimize the data loading, pre-processing, and analyzing process. Datasets with millions of rows can be processed using Pandas smoothly. map, apply, & applymap are such methods that allow element-wise modification of a Dataframe or Series.

Analyzing the model metric is one of the most crucial tasks while training any Machine Learning or Deep Learning model. It allows us to diagnose the model statistics if the model prediction is not up to the mark. In this article, I will discuss how we can log the model metric from model architecture, hardware metric and epoch data in Wandb.ai.

Natural Language Processing is a field of study focusing on computer understanding of human or “natural” language. In this article, we will explore the most basic NLP technique - The bag of Words model

*args and **kwargs are special syntax's used while defining a function to pass a variable number of arguments. We will look at how to use them in the code examples below.
It is not complusory to use args and kwargs as parameter name, you can simply add the asterisk's but it is common practise to them so we will be sticking with that today.

In this notebook, we will learn how to download a Kaggle dataset using the open datasets library with an API token.

Kaggle is an online community platform for data scientists and machine learning enthusiasts. It allows users to find and publish data sets, explore and build models in a web-based data-science environment.

Python provides four basic inbuilt data structures that are: List, Tuple, Dictionary, and Set. To iterate through them, we use skills called Slicing and Indexing. Before getting into these, we need to understand the concept of an Index.

AVG() as an aggregate function is used to return a single value as the average of a stated numeric column. When used as a window function, it will still return the average of a specific column but instead of returning a single value, it will return the running average at each row/window.

Window Functions perform computation over a set of rows called windows and return an aggregated value for each row. In this notebook, we will look at how a window function is executed within a SQL query.

Window Functions perform computation over a set of rows called windows and return an aggregated value for each row. Aggregate Functions are used to return a summarised value of multiple rows that make some mathematical sense. You can use aggregate functions as Window Functions with the help of the OVER() clause.

The shell is the outermost layer around an operating system that uses utilities called commands to interact and access your computer's OS services. It allows users to enter a command instead of clicking buttons and returns a result within the terminal itself.
There are several commands that you can use on the terminal. Below we will be looking at some basic and most frequent commands that are used to navigate through the filesystem.
