🧠 Basic Concepts and Terminology

Neural Network:

A computational model inspired by biological neural networks. It consists of layers of interconnected nodes (neurons) where each connection has a weight that adjusts as learning proceeds.

TensorFlow and Keras:

• TensorFlow: An open-source library for numerical computation and machine learning.
• Keras: A high-level neural networks API that simplifies deep learning experimentation.

Train-Test Split:

The dataset is divided into training, validation, and test sets to ensure the model is evaluated on unseen data.

Outlier Removal:

Removing data points that significantly differ from others to prevent skewing the model's results.

StandardScaler:

Standardizes features by removing the mean and scaling to unit variance, ensuring consistent scale across features.

Loss Function:

Measures the error between the predicted output and the actual output. BinaryCrossentropy is used for binary classification tasks like predicting flood probability.

Model Evaluation Metrics:

• Accuracy: Percentage of correct predictions made by the model.
• R² Score: Statistical measure of how well the model’s predictions approximate actual data points.
