Pooling is a fundamental operation in Convolutional Neural Networks that reduces feature map size, controls memory usage, and addresses translation variance. This article explains why pooling is needed after convolution, how max pooling works step by step, pooling on volumes, and the advantages and limitations of different pooling techniques in deep learning models.

Padding and strides are key concepts in convolutional neural networks that control spatial dimensions and efficiency. This article explains why padding preserves boundary information and spatial size, how zero padding works mathematically, and how stride reduces feature map resolution. With clear intuition and formulas, it shows how padding maintains detail while strided convolution enables efficient downsampling.

Convolution is the core operation behind Convolutional Neural Networks (CNNs) that enables machines to understand images. This blog explains convolution from first principles, starting with how images are represented in memory and progressing to edge detection, feature maps, RGB convolution, and the role of multiple filters. Through intuitive explanations and practical examples, you will gain a clear understanding of how CNNs extract hierarchical features from images.

Standard Gradient Descent is rarely enough for modern neural networks. In this guide, we trace the evolution of optimization algorithms—from the 'look-ahead' mechanism of Nesterov Accelerated Gradient to the adaptive learning rates of Adagrad and RMSProp. Finally, we demystify Adam to understand why it combines the best of both worlds.

Convolutional Neural Networks (CNNs) are inspired by how our visual cortex understands shapes, edges, and patterns. This blog explains CNNs with simple intuition, real experiments like the Hubel & Wiesel cat study, the evolution from the Neocognitron to modern deep learning models, and practical applications in computer vision.

In the rugged landscape of Deep Learning loss functions, standard Gradient Descent often struggles with local minima, saddle points, and the infamous "zig-zag" path. This article breaks down the geometry of loss landscapes—from 2D curves to 3D contours—and explains how Momentum Optimization acts as a confident driver. Learn how using a simple velocity term and the "moving average" of past gradients can significantly accelerate model convergence and smooth out noisy training p

Exponential Weighted Moving Average (EWMA) is a core technique used to smooth noisy time-series data and track trends. In this post, we break down the intuition, mathematical formulation, step-by-step example, and proof behind EWMA — including why it plays a crucial role in optimizers like Adam and RMSProp.

Training a neural network is fundamentally an optimization problem. This blog explains the role of optimizers in deep learning, how gradient descent works, its batch, stochastic, and mini-batch variants, and why challenges like learning rate sensitivity, local minima, and saddle points motivate advanced optimization techniques.

Batch Normalization is a powerful technique that stabilizes and accelerates the training of deep neural networks by normalizing layer activations. This article explains the intuition behind Batch Normalization, internal covariate shift, the step-by-step algorithm, and why BN improves convergence, gradient flow, and overall training stability.

Weight initialization plays a critical role in training deep neural networks. Poor initialization can lead to vanishing or exploding gradients, symmetry issues, and slow convergence. In this article, we explore why common methods like zero, constant, and naive random initialization fail, and how principled approaches like Xavier (Glorot) and He initialization maintain stable signal flow and enable effective deep learning.
