Embeddings in Machine Learning: Everything You Need to Know

#artificialintelligence

I like puppies and soulcycle. Embeddings have pervaded the data scientist's toolkit, and dramatically changed how NLP, computer vision, and recommender systems work. However, many data scientists find them archaic and confusing. Many more use them blindly without understanding what they are. In this article, we'll deep dive into what embeddings are, how they work, and how they are often operationalized in real-world systems. To understand embeddings, we must first understand the basic requirements of a machine learning model. Specifically, most machine learning algorithms can only take low-dimensional numerical data as inputs. In the neural network below each of the input features must be numeric. That means that in domains such as recommender systems, we must transform non-numeric variables (ex.


DeepMind & IDSIA Introduce Symmetries to Black-Box MetaRL to Improve Its Generalization Ability

#artificialintelligence

A new study from a DeepMind and Swiss AI Lab IDSIA team proposes using symmetries from backpropagation-based learning to boost the meta-generalization capabilities of black-box meta-learners. Meta reinforcement learning (RL) is a technique used to automatically discover new RL algorithms from agents' environmental interactions. While black-box approaches in this space are relatively flexible, they struggle to discover RL algorithms that can generalize to novel environments. In the paper Introducing Symmetries to Black Box Meta Reinforcement Learning, the researchers explore the role of symmetries in meta generalization and show that introducing more symmetries to black-box meta-learners can improve their ability to generalize to unseen action and observation spaces, tasks, and environments. The researchers identify three key symmetries that backpropagation-based systems exhibit: use of the same learned learning rule across all nodes of the neural network; the flexibility to work with any input, output and architecture size; and invariance to permutations of the inputs and outputs (for dense layers).

Google's DeepMind faces suit over UK health data

#artificialintelligence

DeepMind Faces: Google's AI department, otherwise known as DeepMined, the Google-owned AI research company, is the subject of a lawsuit. The lawsuit focuses on the company's use of the personal records of a whopping 1.6 million UK National Service patients, including confidential medical records. The #Google #AI department is getting a class-action lawsuit for gaining 1.6 million confidential medical records of #NHS patients. According to PCGamer, DeepMind received the documents to create a health application the company calls Streams. It was supposed to be an AI-based assistant to help healthcare workers and was previously used by the British National Health Service.

Humana leverages Microsoft Cloud for Healthcare to develop advanced predictive models

#artificialintelligence

This blog post has been co-authored by Slawek Kierner, SVP of Enterprise Data & Analytics, Humana and Tie-Yan Liu, Assistant Managing Director, Microsoft Research China. Trips to the hospital happen. And while everyone in the industry strives to deliver world-class care for in-patient experiences, everyone--patients and care teams alike, would prefer to avoid those stays at the hospital. The teams at Humana believed they had enough data to explore the possibility of proactively identifying when patients were heading toward a high-risk event, and they put Microsoft Cloud for Healthcare and AI technology to the test. Humana's questions were straightforward: How do we take the data we have today and use it proactively?


How Does a Neural Network Mimic the Human Brain?

#artificialintelligence

Like biological neurons, these artificial neurons form nodes. These nodes form neural nets. Like biological neural networks, layers are formed. In ANNs, however, these layers come in many varieties: first layer, next layer, node layer, convolutional layer, recurrent layer, input layer, an output layer, hidden layer, deep layer, the final layer, etc. These layers are used to form neural networks, and these networks also come in varieties: deep neural networks, deep-learning networks, convolutional neural networks (CNN), recurrent neural networks (RNN), etc.


A deep learning framework for unsupervised affine and deformable image registration

#artificialintelligence

Recent studies have shown that deep learning methods, notably convolutional neural networks (ConvNets), can be used for image registration. Thus far training of ConvNets for registration was supervised using predefined example registrations. However, obtaining example registrations is not trivial. To circumvent the need for predefined examples, and thereby to increase convenience of training ConvNets for image registration, we propose the Deep Learning Image Registration (DLIR) framework for unsupervised affine and deformable image registration. In the DLIR framework ConvNets are trained for image registration by exploiting image similarity analogous to conventional intensity-based image registration. After a ConvNet has been trained with the DLIR framework, it can be used to register pairs of unseen images in one shot. We propose flexible ConvNets designs for affine image registration and for deformable image registration. By stacking multiple of these ConvNets into a larger architecture, we are able to perform coarse-to-fine image registration. We show for registration of cardiac cine MRI and registration of chest CT that performance of the DLIR framework is comparable to conventional image registration while being several orders of magnitude faster.",

Researchers develop a tool to quantify the beauty of a landscape using artificial intelligence - Actu IA

#artificialintelligence

Evaluating and quantifying the beauty of a landscape, an ecosystem and its effects on a person's well-being has become a central issue for public authorities. With this in mind, scientists from the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland and Wageningen University in the Netherlands have developed a new indicator based on deep learning and several million photos posted on the social network Flickr. An article was recently published in Nature Scientific Reports. When we walk in nature, whether in the mountains, in a forest or by the sea, we feel things, a certain well-being. Numerous studies have highlighted the benefits of such activities for our health, both physical and mental.
