AI • Machine Learning • Tech on Instagram: "Gradient descent is an important AI algorithm that helps machine learning models learn by improving themselves over time. Imagine you’re trying to find the lowest point in a landscape with hills while blindfolded—you’d take small steps in the direction that feels downhill. Similarly, gradient descent adjusts a model’s internal parameters (weights and biases in a neural network) by calculating the direction and size of the “step” needed to reduce error—

Artificial Intelligence | AI on Instagram: "K-Nearest Neighbours (KNN) is a simple and intuitive supervised machine learning algorithm that makes predictions based on how similar things are to each other. They can be used for classification and regression. Imagine you have a scatter plot with red and blue points, where red points represent one class and blue points represent another class. Now, let’s say you get a new data point you haven’t seen before, and want to know if it should be red or bl

AI in 1min on Instagram: "Data science interview question 11: Random Forest is a supervised machine learning algorithm that can be used for both classification and regression tasks. It works by building multiple decision trees during training, and the final output is determined based on the collective predictions of all the trees. For classification problems, the final output is the class predicted by the majority of the trees. For regression tasks, the final output is the average of all the pre

AI • Machine Learning • Tech on Instagram: "Gradient descent is an optimization algorithm widely used in machine learning to minimize a loss function, which is a measure of how well a model’s predictions match the actual outcomes. In the gradient descent process, the model iteratively adjusts its parameters (its weights and biases) to reduce the loss. The parameters are adjusted based on the gradient, or partial derivatives, of the loss function with respect to each parameter. The gradient point

Deeply AI: AI, ChatGPT, Robotics, Data Science on Instagram: "Logistic regression is a statistical method and machine learning algorithm used for binary classification, where the aim is to predict one of two possible outcomes (like yes or no). It works by producing probabilities through a logistic (sigmoid) function, which converts the linear model’s output into a value between 0 and 1. This makes it suitable for predicting categorical variables. The model learns by adjusting weights (or coeffic

AI • Machine Learning • Tech on Instagram: "A neural network “learns” by adjusting its parameters (weights and biases) by increasing or decreasing them numerically so that the network can make increasingly more accurate predictions. The output is compared to the actual target values using a loss function, which quantifies the prediction error. To minimize the error, the network performs backpropagation, an algorithm that computes the gradient (set of all partial derivatives) of the loss with res
