Greedy algorithm.This algorithm solves optimization problems by finding the locally optimal solution, hoping it is the optimal solution at the global level. However, it does not guarantee the most optimal solution. Recursive algorithm.This algorithm calls itself repeatedly until it solves a problem. R...
Whether it’s right or wrong, a “backpropagation” algorithm adjusts the parameters—that is, the formulas’ coefficients—in each cell of the stack that made that prediction. The goal of the adjustments is to make the correct prediction more probable. “It does this for right answers, too...
Matrix factorization using the alternating least squares (ALS)algorithm approximates the sparse user item rating matrix u-by-i as the product of two dense matrices, user and item factor matrices of size u × f and f × i (where u is the number of users, i the number of items and f ...
A machine learningalgorithmis the method by which the AI system conducts its task, generally predicting output values from given input data. The two main processes involved with machine learning (ML) algorithms are classification and regression. AnML algorithmis a set of mathematical processes or tec...
Then, through the processes of gradient descent [梯度下降] and backpropagation [反向传播], the deep learning algorithm adjusts and fits itself for accuracy, allowing it to make predictions about a new photo of an animal with increased precision. ...
In the early training stages, the model’s predictions aren’t very good. But each time the model predicts a token, it checks for correctness against the training data. Whether it’s right or wrong, a “backpropagation” algorithm adjusts the parameters—that is, the formulas’ coefficients—...
What Is a Recommendation System? A recommendation system is an artificial intelligence or AI algorithm, usually associated with machine learning, that uses Big Data to suggest or recommend additional products to consumers. These can be based on various criteria, including past purchases, search ...
for simpler tasks or problems where data is limited, traditional algorithms might be more suitable. For instance, if you're sorting a small list of numbers or searching for a specific item in a short list, a basic algorithm would be more efficient and faster than setting up a neural network...
When training a CNN, a loss function is used to measure the error between the predicted and actual output. Common loss functions include mean squared error for regression tasks and categorical cross-entropy for multi-class classification tasks. The backpropagation algorithm is then utilized to update...
Automating audio annotation is very essential for collecting high-quality training data. Whisper is a recent algorithm by OpenAI that helps transcribe audio files in different languages. The transcription is not always accurate when using such automated models, and to correct the initial model's ...
