Machine Learning Algorithms Cheat Sheet

#artificialintelligence

Machine learning is a subfield of artificial intelligence (AI) and computer science that focuses on using data and algorithms to mimic the way people learn, progressively improving its accuracy. This way, Machine Learning is one of the most interesting methods in Computer Science these days, and it's being applied behind the scenes in products and services we consume in everyday life. In case you want to know what Machine Learning algorithms are used in different applications, or if you are a developer and you're looking for a method to use for a problem you are trying to solve, keep reading below and use these steps as a guide. Machine Learning can be divided into three different types of learning: Unsupervised Learning, Supervised Learning, and Semi-supervised Learning. Unsupervised learning uses information data that is not labeled, that way the machine should work with no guidance according to patterns, similarities, and differences. On the other hand, supervised learning has a presence of a "teacher", who is in charge of training the machine by labeling the data to work with. Next, the machine receives some examples that allow it to produce a correct outcome.


Lessons from infant learning for unsupervised machine learning - Nature Machine Intelligence

#artificialintelligence

The desire to reduce the dependence on curated, labeled datasets and to leverage the vast quantities of unlabeled data has triggered renewed interest in unsupervised (or self-supervised) learning algorithms. Despite improved performance due to approaches such as the identification of disentangled latent representations, contrastive learning and clustering optimizations, unsupervised machine learning still falls short of its hypothesized potential as a breakthrough paradigm enabling generally intelligent systems. Inspiration from cognitive (neuro)science has been based mostly on adult learners with access to labels and a vast amount of prior knowledge. To push unsupervised machine learning forward, we argue that developmental science of infant cognition might hold the key to unlocking the next generation of unsupervised learning approaches. We identify three crucial factors enabling infants’ quality and speed of learning: (1) babies’ information processing is guided and constrained; (2) babies are learning from diverse, multimodal inputs; and (3) babies’ input is shaped by development and active learning. We assess the extent to which these insights from infant learning have already been exploited in machine learning, examine how closely these implementations resemble the core insights, and propose how further adoption of these factors can give rise to previously unseen performance levels in unsupervised learning. Unsupervised machine learning algorithms reduce the dependence on curated, labeled datasets that are characteristic of supervised machine learning. The authors argue that the developmental science of infant cognition could inform the design of unsupervised machine learning approaches.


Joining the dark side with Generative Adversarial Networks

#artificialintelligence

Artificial intelligence methods can be categorized into two different types: discriminative models and generative models. We may show the distinction between the two using an example. Let's say we have a set of points that have simply one feature: they can either have a dashed contour or a solid contour. We can graph the points by arranging them along a line we call the x-axis. The axis permits a visual representation of our points' characteristics.


Semi-Supervised Learning

#artificialintelligence

Image classification is the most common computer vision problem where an algorithm process an image and classifies the classes. This technique extended with object detection algorithms, where it uses localization with the classification. In object detection methods object is localized by a bounding box, where the bounding box is represented by four value points according to the pixels in an image. If you are trying to train an object detection model with custom data, human resources are required to annotate enormous amounts of data manually. Consider a large amount of image data set that need to train on a model, and manually labeling all of this data ourselves may take a long time and logistically difficult.


What is Machine Learning?

#artificialintelligence

Although machine learning (ML) has been around for decades, its practical applications are now coming into focus as it helps companies better understand their customers. Available data from sources such as social media, mobile devices, and Internet of Things (IoT) devices is growing rapidly--we're now generating an estimated 2.5 quintillion bytes of data every day. This flood of information has made machine learning more accessible than ever before. To leverage the full potential of machine learning, however, it's important to understand what it is, how it works, why it's important, and the applicable use cases for your business. Machine learning is a subset of artificial intelligence (AI) that allow systems to learn and improve from experience without being explicitly programmed. It involves algorithms that make dynamic decisions and predictions based on historical data rather than following static program instructions for specific tasks and outcomes.


Using AI as a perception-altering drug

#artificialintelligence

They all had some effect, surely. Could I have done it without them? Hang on, what *is* the it that I wouldn't have done? Real life usually lacks counterfactuals. I sense this topic could add some spice to the discussions of those who have been asking about the role of psychoactive substances in art since time immemorial, though the AI component adds nothing fundamentally new.


A Brief Introduction to Fundamentals of Machine Learning

#artificialintelligence

Data adventure, which started with data mining concept, has been in a continuous development with introducing different algorithms. There are many applicable algorithms in AI. Besides, AI is actively used in marketing, health, agriculture, space, and autonomous vehicle production for now. Data mining is divided into different models according to fields in which it is used. These models can be grouped under four main headings as a value estimation model, database clustering model, link analysis, and difference deviations.


A guide to machine learning in search: Key terms, concepts and algorithms

#artificialintelligence

When it comes to machine learning, there are some broad concepts and terms that everyone in search should know. We should all know where machine learning is used, and the different types of machine learning that exist. Read on to gain a better grasp of how machine learning impacts search, what the search engines are doing and how to recognize machine learning at work. Let's start with a few definitions. Then we'll get into machine learning algorithms and models.


Graph Machine Learning with Python Part 4: Supervised & Semi-Supervised Learning

#artificialintelligence

This story will explore how we can reason from and model graphs using labels via Supervised and Semi-Supervised Learning. I'm going to be using a MET Art Collections dataset that will build on my previous parts on Metrics, Unsupervised Learning, and more. Be sure to check out the previous story before this one to keep up on some of the pieces as I won't cover all concepts again in this one: The easiest approach to conduct Supervised Learning is to use graph measures as features in a new dataset or in addition to an existing dataset. I have seen this method yield positive results for modeling tasks, but it can be really dependent on 1. how you model as a graph (what are the inputs, outputs, edges, etc.) and 2. which metrics to use. Depending on the prediction task, we could compute node-level, edge-level, and graph-level metrics.
