Python Array Squaring: Simplify the Complex

Quick summary Squaring can change order: negative values make a sorted input different from a sorted list of squares. Compare both ends: two pointers identify the largest remaining absolute value. Build the sorted result efficiently: place larger squares at the end and move the corresponding pointer inward. Use the structure of the input: the sorted-array […]

What is bias and variance in machine learning?

Quick summary High bias misses useful patterns: an overly simple model can make systematic prediction errors. High variance follows noise: predictions can change sharply when the training data changes. Compare training and test behaviour: underfitting and overfitting show different error patterns. Aim for generalisation: learning the training set well is not enough if performance fails […]

Machine Learning

Entropy, Information gain, and Gini Index: Decision Tree

Quick summary Decision trees split data through questions: branches lead from feature tests to predictions at leaf nodes. Choose informative splits: the goal is to reduce uncertainty about the target. Entropy and information gain are related: information gain measures the reduction in entropy after a split. Gini provides another criterion: impurity measures help compare candidate […]

Machine Learning

What are “ensemble methods”?

Quick summary Combine multiple models: an ensemble brings individual predictions together. Reduce prediction error: the article frames ensembles as a way to address bias or variance. Recognise common approaches: bagging, boosting and stacking organise combinations differently. Random forests are one example: they aggregate the predictions of multiple decision trees. An ensemble methods are technique which uses […]

Difference Between Classification and Regression in Machine Learning

Quick summary Classification predicts categories: the target is a class label, sometimes supported by a probability. Regression predicts quantities: the target represents a numerical amount. Some model families support both: the task and configuration determine how they are used. Match evaluation to the target: choose metrics that reflect the prediction problem rather than judging all […]

Machine Learning

Balancing Act: Mastering Underfitting & Overfitting

Quick summary Underfitting misses the signal: a model may be too simple to capture useful relationships. Overfitting follows noise: strong training performance can hide poor results on new data. Inspect both kinds of error: training and validation behaviour help distinguish the problems. Adjust complexity deliberately: features, model flexibility and regularisation influence the balance. Welcome to […]

Machine Learning

Relationship between bias, variance, and test set MSE

Quick summary Model flexibility changes the balance: the examples show bias falling while variance rises. The best balance depends on the data: a near-linear relationship behaves differently from a strongly nonlinear one. Test error guides the choice: a more flexible model does not necessarily produce a better result. Avoid either extreme: useful generalisation requires controlling […]
