Struggling with Machine Learning algorithms? 🤖
Then you better stay with me! 🤓
We are going back to the basics to simplify ML algorithms.
... today's turn is Logistic Regression! 👇🏻
1️⃣ 𝗟𝗢𝗚𝗜𝗦𝗧𝗜𝗖 𝗥𝗘𝗚𝗥𝗘𝗦𝗦𝗜𝗢𝗡
It is a binary classification model used to classify our input data into two main categories.
It can be extended to multiple classifications... but today we'll focus on a binary one.
Also known as Simple Logistic Regression.
2️⃣ 𝗛𝗢𝗪 𝗧𝗢 𝗖𝗢𝗠𝗣𝗨𝗧𝗘 𝗜𝗧?
The Sigmoid Function is our mathematical wand, turning numbers into neat probabilities between 0 and 1.
It's what makes Logistic Regression tick, giving us a clear 'probabilistic' picture.
3️⃣ 𝗛𝗢𝗪 𝗧𝗢 𝗗𝗘𝗙𝗜𝗡𝗘 𝗧𝗛𝗘 𝗕𝗘𝗦𝗧 𝗙𝗜𝗧?
For every parametric ML algorithm, we need a LOSS FUNCTION.
It is our map to find our optimal solution or global minimum.
(hoping there is one! 😉)
✚ 𝗕𝗢𝗡𝗨𝗦 - FROM LINEAR TO LOGISTIC REGRESSION
To obtain the sigmoid function, we can derive it from the Linear Regression equation.

Essential Data Science Key Concepts
1. Data: Data is the raw information that is collected and stored. It can be structured (in databases or spreadsheets) or unstructured (text, images, videos). Data can be quantitative (numbers) or qualitative (denoscriptions).
2. Data Cleaning: Data cleaning involves identifying and correcting errors in the dataset, handling missing values, removing outliers, and ensuring data quality before analysis.
3. Data Exploration: Data exploration involves summarizing the main characteristics of the data, understanding data distributions, identifying patterns, and detecting correlations or relationships within the data.
4. Denoscriptive Statistics: Denoscriptive statistics are used to describe and summarize the main features of a dataset. This includes measures like mean, median, mode, standard deviation, and visualization techniques.
5. Data Visualization: Data visualization is the graphical representation of data to help in understanding patterns, trends, and insights. Common visualization tools include bar charts, histograms, scatter plots, and heatmaps.
6. Statistical Inference: Statistical inference involves drawing conclusions from data with uncertainty. It includes hypothesis testing, confidence intervals, and regression analysis to make predictions or draw insights from data.
7. Machine Learning: Machine learning is a subset of artificial intelligence that uses algorithms to learn from data and make predictions or decisions without being explicitly programmed. It includes supervised learning, unsupervised learning, and reinforcement learning.
8. Feature Engineering: Feature engineering is the process of selecting, transforming, and creating features (input variables) to improve model performance in machine learning tasks.
9. Model Evaluation: Model evaluation involves assessing the performance of a machine learning model using metrics like accuracy, precision, recall, F1 score, ROC-AUC, and confusion matrix.
10. Data Preprocessing: Data preprocessing involves preparing the data for analysis or modeling. This includes encoding categorical variables, scaling numerical data, and splitting the data into training and testing sets.
