Evaluation metrics for classification ML model
Accuracy: measures the overall correctness of the model
Precision: measures the proportion of true positive predictions among all positive predictions
Recall: measures the proportion of true positive predictions among all actual positives
F1 Score: harmonic mean of precision and recall
Confusion Matrix: provides a summary of correct and incorrect predictions
Precision and recall are used in evaluating the performance of classification models.
Precision is used when the goal is to minimize false positives.
Recall is used when the goal is to minimize false negatives.
Precision is calculated as TP / (TP + FP) where TP is true positives and FP is false positives.
Recall is calculated as TP / (TP + FN) where FN is false negatives.
In medical field, precision is important when identi...
Null values can be handled by either removing them, replacing them with a default value, or imputing them with a calculated value.
Remove null values from the dataset
Replace null values with a default value (e.g. 0 for numerical data, 'Unknown' for categorical data)
Impute null values with a calculated value (e.g. mean, median, mode)
Window functions and aggregate functions in SQL
Window functions perform calculations across a set of table rows related to the current row
Aggregate functions perform a calculation on a set of values and return a single value
Examples of window functions include ROW_NUMBER(), RANK(), and LAG()
Examples of aggregate functions include SUM(), AVG(), and COUNT()

Four-wheel drive can be engaged or disengaged depending on the driving conditions.
It is different from all-wheel drive, which powers all four wheels all the time.
Examples of vehicles w...
Differential in a vehicle allows wheels to rotate at different speeds, enabling smooth turns and preventing tire wear.
Differential is a mechanism that splits torque between wheels on an axle
It allows wheels to rotate at different speeds while maintaining power to both wheels
Without differential, the wheels would be forced to rotate at the same speed, making turns difficult and causing tire wear

Piston rings are crucial components in internal combustion engines that prevent oil and fuel from leaking into the combustion chamber.
Piston rings create a seal between the piston and cylinder wall, allowing the engine to build compression and power.
They also help regulate oil consumption and prevent excessive oil from entering the combustion chamber.
Piston rings can wear out over time, leading to decreased engine perf...
