Technical Interview Question: 1. How does Python handle memory management and garbage collection? Answer : Python uses reference counting to track object references and a cyclic garbage collector to handle circular references. When an object’s reference count drops to zero, it’s deallocated. The gc module detects cycles using a mark-and-sweep algorithm. Example : import gc class Node : def __init__ (self): self. next = None node1, node2 = Node(), Node() node1. next , node2. next = no...

  Classification Tutorial: Linear and Non-Linear Models with Heart Disease Dataset Introduction Classification is a machine learning task where we assign a category (class) to an input based on its features. For example, predicting whether a patient has heart disease (yes/no) based on medical data. Classification algorithms are divided into: Linear Models : Assume classes can be separated by a straight line (or hyperplane in higher dimensions). Non-Linear Models : Capture complex, curved boundaries between classes. For Beginners : Think of classification like sorting fruits into apples and oranges. Linear models draw a straight line to separate them, while non-linear models draw wiggly lines to handle trickier cases where apples and oranges are mixed in complex patterns. For Professionals : Classification involves learning a function ( f(X) \to y ), where ( X ) is the feature matrix and ( y ) is the class label (e.g., 0 or 1). Linear models assume ( f ) is a linear combinat...
