Do you often receive emails saying that you have won $1 million or free mobile recharges for life? These emails are generally spam and are sent in bulk to users to trick them. In this story, we’ll build a classifier that will mark emails as spam or non-spam based on the text that they contain. We will use the Spam Mails Dataset from Kaggle to train the classifier.

What is a Cache?

A cache is a memory used for the storage of frequently used data so that this data can be fetched quickly for subsequent calls. In Python, the library functools gives us the ability to implement a cache. This cache stores the result of previous operations to speed up our function calls.

LRU Cache

The LRU Cache is a type of cache in which the least recently used data is discarded first. This LRU algorithm keeps track of which data was used when. For speeding up the python functions, we will use an LRU cache. …

Disasters can be unexpected and life-threatening. We will analyze and classify disaster tweets in this tutorial. For this purpose, we will use the Disaster Tweets dataset from Kaggle.

Dogecoin (DOGE) is a cryptocurrency created as a joke, making fun of the wild speculation in cryptocurrencies at the time. Dogecoin features the face of the Shiba Inu dog from the “Doge” meme as its logo. It has quickly developed its own online community, reaching a gigantic market capitalization. In this tutorial, we will predict the prices of Dogecoin. For this purpose, we’ll use the Dogecoin Historical Data from Kaggle.

Alexa is an AI-based virtual assistant developed by Amazon. It is today used in devices like Echo, Dot, and Firestick. It is capable of voice interaction, music playback, setting alarms, home automation, and providing weather information. We will do sentiment analysis on the reviews of Alexa products posted on Amazon. For this, we’ll use the Alexa Reviews dataset from Kaggle.

A stroke occurs when the blood supply to part of your brain is interrupted, preventing brain tissue from getting oxygen and nutrients. Due to this, brain cells begin to die in minutes. We’ll use 11 features of a person to predict whether they will get a stroke or not.

Can we predict the price of Bitcoin, an asset that is so volatile? Let’s try to find out. We will use the Bitcoin Historical dataset to predict Bitcoin price.

Loading the Dataset

We’ll have downloaded the data from Kaggle and unzipped it. Let us load it into our notebook now.

bitcoin = pd.read_csv('./bitcoin/bitstampUSD_1-min_data_2012-01-01_to_2021-03-31.csv')

Exploring the Dataset

Let’s print the shape of the dataset.

The Titanic struck an iceberg on 15 April 1912 that caused its sinking, leading to the death of more than 1,500 people. This made it one of the deadliest sinking of a single ship. We will try to predict whether a particular person on Titanic survived or not using 11 features about them. For this purpose, we will use the Titanic dataset from Kaggle.
