Classification is a fundamental task in machine learning, involving assigning predefined labels to input data points. Here are 100 tips for working with classification models:

1. Basics of Classification:

1. Understand the fundamental concepts of classification, where the goal is to assign labels to instances.
2. Distinguish between binary and multiclass classification tasks.

2. Data Preparation:

1. Handle imbalanced classes using techniques like oversampling, undersampling, or synthetic data generation.
2. Normalize or standardize numerical features to ensure equal influence.

3. Exploratory Data Analysis:

1. Visualize class distributions to understand the balance or imbalance in the dataset.
2. Use box plots or violin plots to identify potential outliers.

4. Feature Engineering:

1. Create meaningful features that enhance the model’s ability to discriminate between classes.
2. Consider dimensionality reduction techniques like PCA for high-dimensional data.
