K-Nearest Neighbors clearly explained 👇 KNN is a versatile supervised learning algorithm widely employed in both classification and regression tasks.

Unlike complex models, KNN relies on the proximity of data points to make predictions, making it intuitive and easy to implement.

Normal Distribution clearly explained 👇 A normal distribution, also known as a Gaussian distribution, is the most typical distribution you'll find in your days features.

It's characterized by several key properties that give it a distinctive bell curve shape.

Where can you find the most common data distributions? (2nd part)

Check this thread for real-world examples! 🧵 👇 5️⃣ Exponential Distribution:

Often found in scenarios related to the time until an event occurs, such as the lifetime of an electronic component or the time until the next earthquake occurs.

In Data Science you can find multiple data distributions...

But where are they typically found? 🤔

What is the difference between seasonality and cyclicality in time series forecasting❓

Discover it below 👇

🧵 Seasonality and cyclicality are two essential concepts that play a crucial role in understanding patterns within time series data.

Let's start with seasonality! 🌞🍂❄️

Have you ever wondered how 𝗦𝘂𝗽𝗽𝗼𝗿𝘁 𝗩𝗲𝗰𝘁𝗼𝗿 𝗠𝗮𝗰𝗵𝗶𝗻𝗲𝘀 (SVM) can handle non-linear data?

The "𝗞𝗲𝗿𝗻𝗲𝗹 𝗧𝗿𝗶𝗰𝗸" is a fascinating mathematical technique that allows efficient calculations and delivers powerful results!

Let's learn more about it 🧵 👇 In SVM, the kernel trick is a clever way to perform complex calculations in a higher-dimensional feature space without explicitly transforming the original data into that space.

It's like finding a hidden pathway to handle non-linear relationships between data points.

In time series analysis, the trend component is key.

It indicates the directional movement of data over time.

Let's learn more about the trend 👇🧵 The trend component represents the overall direction data moves over an extended period.

It captures systematic patterns like gradual increases, decreases, or stable periods. The trend reflects long-term shifts in the data.

Do you want to get the feature importance using SHAP?

Wait no more, here you have a code snippet 👇

1. Import Libraries:
Import necessary libraries, including 𝚜𝚑𝚊𝚙 and 𝚁𝚊𝚗𝚍𝚘𝚖𝙵𝚘𝚛𝚎𝚜𝚝𝚁𝚎𝚐𝚛𝚎𝚜𝚜𝚘𝚛.

2. Model Training:
Initialize and train any model, for example a Random Forest Regressor model using 𝚇_𝚝𝚛𝚊𝚒𝚗 (features) and 𝚢_𝚝𝚛𝚊𝚒𝚗 (labels).

𝗙𝗲𝗮𝘁𝘂𝗿𝗲 𝗜𝗺𝗽𝗼𝗿𝘁𝗮𝗻𝗰𝗲 measures the contribution of each feature to the model's predictions.

It is crucial in Machine Learning for several reasons.

Let's see them 🧵👇 1️⃣ Model Interpretability

Understanding which features are most important in making predictions helps to interpret the model's behavior.

It provides insights into the underlying patterns learned by the model and helps in building trust among stakeholders.

SHAP is a powerful technique in machine learning for interpreting the output of complex models.

Commonly used for ✨Feature Engineering✨

Let's explore SHAP further 🧵 👇 It stands for “SHapley Additive exPlanations”.

It is a model agnostic method, which means that it can be applied to any model. This is particularly useful for black-box models where understanding how individual features contribute to predictions might otherwise be challenging.

ARIMA is one of the most popular traditional statistical methods used for time series forecasting.

Let's understand its components 🧵 👇 ARIMA stands for Auto-Regressive Integrated Moving Average.

It is composed of 3 components:

🔹 Auto-Regressive (AR)
🔹 Integrated (I)
🔹 Moving Average (MA)

What is the difference between Classification and Regression in Machine Learning? 🤔

🧵 👇 Both Regression and Classification involve predicting outcomes based on input data, however, they differ in terms of the nature of the target variable and the goals they aim to achieve.

Let's find out more...

Permutation importance is a model-agnostic technique used to assess the importance of features in a model.

This method involves systematically shuffling each feature's values one at a time and measuring the resulting change in model performance. I said that it is a model-agnostic technique, but what does that mean?

It refers to a technique that is not tied to any specific ML model. It can be applied to various types of models without being dependent on the internal characteristics or algorithms of a particular model.
