Training a Machine Learning Model on a Dataset with Highly-Correlated Features

#artificialintelligence

In a previous article, we've shown that a covariance matrix plot can be used for feature selection and dimensionality reduction: Feature Selection and Dimensionality Reduction Using Covariance Matrix Plot. We, therefore, were able to reduce the dimension of our feature space from 6 to 4. Now suppose we want to build a model on the new feature space for predicting the crew variable. Looking at the covariance matrix plot between features, we see that there is a strong correlation between the features (predictor variables), see the image above. In this article, we shall use a technique called Principal Component Analysis (PCA) to transform our features into space where the features are independent or uncorrelated. We shall then train our model on the PCA space.


Analysing Machine Learning Models with Imandra

#artificialintelligence

The vast majority of work within formal methods (the area of computer science that reasons about hardware and software as mathematical objects in order to prove they have certain properties) has involved analysing models that are fully specified by the user. More and more, however, critical parts of algorithmic pipelines are constituted by models that are instead learnt from data using artificial intelligence (AI). The task of analysing these kinds of models presents fresh challenges for the formal methods community and has seen exciting progress in recent years. While scalability is still an important, open research problem -- with state-of-the-art machine learning (ML) models often having millions of parameters --in this post we give an introduction to the paradigm by analysing two simple yet powerful learnt models using Imandra, a cloud-native automated reasoning engine bringing formal methods to the masses! Verifying properties of learnt models is a difficult task, but is becoming increasingly important in order to make sure that the AI systems using such models are safe, robust, and explainable.


What Is Machine Learning Models And Its Power

#artificialintelligence

Appropriately utilized Machine Learning (ML) adaptations may beneficially affect authoritative adequacy. It's first basic to understand how these renditions are made, how they work, and the manner in which they're set into generation. At the point when a PC is given inquiries inside a specific area, an AI model will run a calculation that will empower it to determine those inquiries. These calculations are not really restricted to specific situations however can be modified to a higher level of precision for particular sorts of inquiries. Use cases for these are recorded underneath.



Hosting a Machine Learning Model in ASP.NET Core 3.0 - Simple Talk

#artificialintelligence

The romantic days of machine learning being the science of a few geeks are over. To be effective and ubiquitous as top managers claim they want it to be in the enterprise, machine learning must move into a more integrated and agile environment and, more than everything else, be effectively hosted in line-of-business applications. In this article, I'll try to explain why this particular point is problematic today that most solutions, including shallow learning solutions, are primarily coded in Python. The essence of the article can be summarized in: a tighter integration between machine learning solutions and host application environments is, at the very minimum, worth exploring. This means looking beyond Python; and machine learning is now available (and fast-growing) right in the .NET platform, natively with existing .NET Framework applications and newer .NET Core applications.


How to Build, Train, Test, and Deploy a Machine Learning Model

#artificialintelligence

Rahul is a Machine Learning Engineer at Figure Eight who is interested in building novel Artificial Intelligence (A.I.) solutions for improving the Human Experience. His AI Philosophy: To contribute towards a future where A.I. is the fabric of a utopian society. A.I. is not about making machines intelligent, but more about reducing human burden. And so, rather than thinking about fictional apocalyptic futures like Hal 9000, Terminator, etc., I prefer to build Agents that work towards social equity, less greed and help humans achieve self-realization.


How to Easily Deploy Machine Learning Models Using Flask - KDnuggets

#artificialintelligence

When a data scientist/machine learning engineer develops a machine learning model using Scikit-Learn, TensorFlow, Keras, PyTorch etc, the ultimate goal is to make it available in production. Often times when working on a machine learning project, we focus a lot on Exploratory Data Analysis(EDA), Feature Engineering, tweaking with hyper-parameters etc. But we tend to forget our main goal, which is to extract real value from the model predictions. Deployment of machine learning models or putting models into production means making your models available to the end users or systems. However, there is complexity in the deployment of machine learning models.


KDD 2019 150 successful Machine Learning models: 6 lessons learned at Booking.com

#artificialintelligence

Booking.com is the world's largest online travel agent where millions of guests find their accommodation and millions of accommodation providers list their properties including hotels, apartments, bed and breakfasts, guest houses, and more. During the last years we have applied Machine Learning to improve the experience of our customers and our business. While most of the Machine Learning literature focuses on the algorithmic or mathematical aspects of the field, not much has been published about how Machine Learning can deliver meaningful impact in an industrial environment where commercial gains are paramount. We conducted an analysis on about 150 successful customer facing applications of Machine Learning, developed by dozens of teams in Booking.com, Following the phases of a Machine Learning project we describe our approach, the many challenges we found, and the lessons we learned while scaling up such a complex technology across our organization.


Online evaluation of machine learning models - O'Reilly Artificial Intelligence Conference in London 2019

#artificialintelligence

Academic machine learning involves almost exclusively offline evaluation of machine learning models. In the real world this is, somewhat surprisingly, often only good enough for a rough cut that eliminates the real dogs. For production work, online evaluation is often the only option to determine which of several final-round candidates might be chosen for further use. As Einstein is rumored to have said, theory and practice are the same, in theory. So it is with models.


Training, validation and testing for supervised machine learning models

#artificialintelligence

Validating and testing our supervised machine learning models is essential to ensuring that they generalize well. SAS Viya makes it easy to train, validate, and test our machine learning models. Training data are used to fit each model. Training a model involves using an algorithm to determine model parameters (e.g., weights) or other logic to map inputs (independent variables) to a target (dependent variable). Model fitting can also include input variable (feature) selection.
