Loss functions for Linear and Logistic Regression and their significance.
Linear Regression uses Mean Squared Error (MSE) as the loss function.
Logistic Regression uses Binary Cross-Entropy (BCE) as the loss function.
MSE measures the average squared difference between the predicted and actual values.
BCE measures the difference between the predicted and actual probabilities.
The goal is to minimize the loss function to imp
Data pre-processing is a crucial step in data analysis that involves cleaning, transforming, and organizing data.
Cleaning data by removing duplicates, filling in missing values, and correcting errors
Transforming data by scaling, normalizing, or encoding categorical variables
Organizing data by splitting into training and testing sets, or creating new features
Exploratory data analysis to identify outliers, correlations, ...
Overfitting occurs when a model is too complex and fits the training data too closely, resulting in poor generalization to new data.
Using a model that is too complex
Having too few training examples
Using irrelevant or noisy features
Not using regularization techniques
Not using cross-validation to evaluate the model
Data leakage
Transfer Learning is used to leverage pre-trained models for new tasks, saving time and resources.
Transfer Learning is used when the dataset for a new task is small or limited.
It can also be used when the new task is similar to the original task the pre-trained model was trained on.
Transfer Learning can save time and resources by using pre-trained models instead of training from scratch.
Examples include using pre-train...

Primary key uniquely identifies a record, while unique key allows only one instance of a value in a column. Query to find last id involves using ORDER BY and LIMIT.
Primary key enforces uniqueness and not null constraint on a column
Unique key enforces uniqueness but allows null values
To find row with last id, use ORDER BY id DESC LIMIT 1 in SQL query
