Unsupervised or Indirectly Supervised Learning


Supervised vs Unsupervised Learning -- What is the difference?

#artificialintelligence

Machine Learning and Artificial Intelligence are rapidly changing the landscape of how organizations function in the world. These fields have become the focus of businessmen and entrepreneurs of all fields. The amount of funding in AI startups has risen to 18.8B USD in the past year. What's more interesting is that the largest category of AI investments is in machine learning that is a subfield of AI. Machine learning is the basic thing powering all AI applications.


Evolution Of Natural Language Processing(NLP)

#artificialintelligence

In this article I want to share about the evolution of text analysis algorithms in last decade. Natural Language(NLP)has been around for a long time, In fact, a very simple bag of words model was introduced in the 1950s. But in this article I want to focus on evolution of NLP during recent times. There has been enormous progress in the field since 2013 due to the evolution and the advancement of machine learning algorithms together with reduced cost of computation and memory. In 2013, a research team led by Thomas Michael off at Google introduced the Word2Vec algorithm.

Machine Learning: Unsupervised Learning

#artificialintelligence

This is the second course in the 3-course Machine Learning Series and is offered at Georgia Tech as CS7641. Taking this class here does not earn Georgia Tech credit. Ever wonder how Netflix can predict what movies you'll like? Or how Amazon knows what you want to buy before you do? The answer can be found in Unsupervised Learning!


Visa on using advanced AI such as unsupervised learning to fight fraud

#artificialintelligence

Join executive leaders at the Data, Analytics, & Intelligent Automation Summit, presented by Accenture. The thing about fraud is that it's constantly changing -- looking at a past attack doesn't guarantee the next attack will look the same or target the same kind of victim -- and defenders have to continuously adapt. Visa utilizes artificial intelligence to analyze all of the transactions that go across the network and track large-scale transactional changes as part of its fraud detection efforts, Melissa McSherry, Visa's senior VP and global head of data, security, and identity products, said at VentureBeat's Transform 2021 virtual conference on Monday. Visa scores all of the transactions that go across the Visa network, which allows the company to define a set of behaviors that would be considered "normal." The team is "constantly" updating the model's view of history and updates the model itself to reflect the data on a fairly regular basis, McSherry said.

Less Labeled Data? Here's the Solution: The SimCLRv2

#artificialintelligence

The complication of learning information from only a few labeled data has troubled machine learning researchers for a long time, especially in applications of computer vision. To tackle this problem, a new research shows promising solution. What's new: A Google Brain Team led by Ting Chen and other fellow colleagues have formulated a simple framework for semi-supervised learning, which utilises very few labeled data and a large amount of unlabeled data to perform classification on the ImageNet database with an accuracy that outperforms the standard supervised training. Key insight: Semi-supervised learning which involves unsupervised pretraining followed by supervised fine-tuning has been copiously used for natural language processing, however, their application in computer vision has shown propitious results only very recently. The researchers carried forward this idea for use in computer vision by developing an improved variant of a previously proposed contrastive learning framework, SimCLR.


Machine Learning Bootcamp: SVM,Kmeans,KNN,LinReg,PCA,DBS

#artificialintelligence

The course covers Machine Learning in exhaustive way. The presentations and hands-on practical are made such that it's made easy. The knowledge gained through this tutorial series can be applied to various real world scenarios. UnSupervised learning does not require to supervise the model. Instead, it allows the model to work on its own to discover patterns and information that was previously undetected. It mainly deals with the unlabeled data.


Microsoft's Project Alexandria parses documents using unsupervised learning

#artificialintelligence

Where does your enterprise stand on the AI adoption curve? Take our AI survey to find out. In 2014, Microsoft launched Project Alexandria, a research effort within its Cambridge research division dedicated to discovering entities -- topics of information -- and their associated properties. Building on the research lab's work in knowledge mining research using probabilistic programming, the aim of Alexandria was to construct a full knowledge base from a set of documents automatically. Alexandria technology powers the recently announced Microsoft Viva Topics, which automatically organizes large amounts of content and expertise in an organization.


Clustering in Machine Learning - GeeksforGeeks

#artificialintelligence

It is basically a type of unsupervised learning method . An unsupervised learning method is a method in which we draw references from datasets consisting of input data without labelled responses. Generally, it is used as a process to find meaningful structure, explanatory underlying processes, generative features, and groupings inherent in a set of examples. Clustering is the task of dividing the population or data points into a number of groups such that data points in the same groups are more similar to other data points in the same group and dissimilar to the data points in other groups. It is basically a collection of objects on the basis of similarity and dissimilarity between them. For ex– The data points in the graph below clustered together can be classified into one single group. We can distinguish the clusters, and we can identify that there are 3 clusters in the below picture. It is not necessary for clusters to be a spherical.
