Gradient descent is an optimization algorithm which is commonly-used to trainmachine learningmodels andneural networks. It trains machine learning models by minimizing errors between predicted and actual results. Training data helps these models learn over time, and the cost function within gradient desc...
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...
The objective function need not be smooth, but the algorithm works best when the objective function is continuous. Surrogate optimization attempts to find a global minimum of an objective function using few objective function evaluations. To do so, the algorithm tries to balance the optimization ...
Deep learning is part of machine learning—a "deep" part, in that the computers can do even more autonomously, with less help from humans. The massive dataset that the computer is trained on is used to form a deep learning neural network: a complex, many-layered, weighted algorithm modeled...
Semantic searchis “a type of search that understands the user’s intent and the relationship between concepts.” You might be wondering, “But isn’t search intent important for SEO in general?” The answer is yes. However, Google’s semantic search algorithm uses artificial intelligence and ...
We at AdPushup, put our focus on page RPM while helping publishers with their revenue goals. This is because we consider every page has unique value when it comes to securing ad dollars. And we achieve this through our machine-learning algorithm and in-housead operationsexpertise.Feel free ...
no explicit consideration for traffic — or his skill sets and inventory. While some models may include this — for example, looking at total travel time based on previous data points — it’s important to include traffic as a critical and explicit part of the route optimization algorithm. ...
Search engine optimization is the science of improving a website to increase its visibility on search engine results pages (SERPs) when people search for products or services. SEO aims to get as much organic or unpaid traffic as possible to a website through search engines, such as Google an...
Surrogate optimization is best suited to time-consuming objective functions. The objective function need not be smooth, but the algorithm works best when the objective function is continuous. Surrogate optimization attempts to find a global minimum of an objective function using few objective function ...
