Train and evaluate custom machine learning models of Watson Developer Cloud - BISILO

#artificialintelligence

Natural Language Classifier (NLC), Watson Conversation, and Visual Recognition services allow developers to train custom ML models by providing example text utterances (NLC and Conversation) and example images (VR) for a defined set of classes (or intents). Furthermore, for custom entity and relation extraction from text, IBM Watson offers Watson Knowledge Studio, a SaaS solution designed to enable Subject Matter Experts (SMEs) to train custom statistical machine learning models for extracting domain-specific entities and relations from text. To help address these questions and enable our partners and clients to exercise the full power of WDC customization capabilities, we've published WDC Jupyter notebooks that report commonly used machine learning performance metrics to judge the quality of a trained model. Specifically, the WDC Jupyter notebooks report machine learning metrics that include accuracy, precision, recall, f1-score, and confusion matrix.


Recycling Deep Learning Models with Transfer Learning

@machinelearnbot

Intuitively, to train a model strong enough to compete with human object recognition capabilities, a similarly large training set might be required. Alex Krizhevsky, Ilya Sutskever and Geoffrey Hinton handily won the 2012 ImageNet competition, establishing convolutional neural networks (CNNs) as the state of the art in computer vision. Following this line of thinking, computer vision researchers now commonly use pre-trained CNNs to generate representations for novel tasks, where the dataset may not be large enough to train an entire CNN from scratch. In the first set of experiments, they split the data by randomly assigning each image category to either subset A or subset B.


Building a Deep Learning Model for Process Optimisation

@machinelearnbot

The objective of this paper is to present the process of building a Deep Learning Model for optimising the output for a Production Process from a Training sample using Weka Multilayer Perceptron. The objective is to maximise the daily Shotcrete Road Development volume (in m3) by identifying the right combination of the agitator trucks which can range from 1 to 4, the agitator tank capacities which can range from 5 to 10 m3, the number of Kibble trucks which can range from 1 to 5, the kibble tank capacities ranging from 2 to 5 m3 and the final parameter being the distance to application site which can range from 1 to 4 Kms. Root mean squared error 0.8258 Root mean squared error 0.5739 Root mean squared error 0.1106 As can be seen above the deep architecture with 3 hidden layers yields the minimum error and hence has been chosen for predicting the Shotcrete output. Having identified the model that would emulate the behaviour of Shotcrete Production process, the next goal is to identify the combination of Agitator trucks, Agitator capacity, Kibble trucks, Kibble capacity and the distance to site that would maximise the Shotcrete output.


Apache Spark MLlib 2.x: Productionize your Machine Learning Models

#artificialintelligence

Apache Spark has rapidly become a key tool for data scientists to explore, understand and transform massive datasets and to build and train advanced machine learning models. How do I embed what I have learned into customer facing data applications? In this latest Data Science Central webinar, we will discuss: Best practices on how customers productionize machine learning models Case studies with actual customers Live tutorials of a few example architectures and code in Python, Scala, Java and SQL Speaker: Richard Garris, Principal Solutions Architect -- Databricks Inc. Hosted by: Bill Vorhies, Editorial Director -- Data Science Central


Build and train machine learning models on our new Google Cloud TPUs

@machinelearnbot

These breakthroughs required enormous amounts of computation, both to train the underlying machine learning models and to run those models once they're trained (this is called "inference"). We've designed, built and deployed a family of Tensor Processing Units, or TPUs, to allow us to support larger and larger amounts of machine learning computation, first internally and now externally. While our first TPU was designed to run machine learning models quickly and efficiently--to translate a set of sentences or choose the next move in Go--those models still had to be trained separately. At the heart of this system is the second-generation TPU we're announcing today, which can both train and run machine learning models.


How to Train a Final Machine Learning Model - Machine Learning Mastery

#artificialintelligence

In this post, you will discover how to finalize your machine learning model in order to make predictions on new data.

The goal of your machine learning project is to arrive at a final model that performs the best, where "best" is defined by: In your project, you gather the data, spend the time you have, and discover the data preparation procedures, algorithm to use, and how to configure it. We gather predictions from the trained model on the inputs from the test dataset and compare them to the withheld output values of the test set.


Creating machine learning models to analyze startup news

#artificialintelligence

This is the second part in a series where we analyze thousands of articles from tech news sites in order to get insights and trends about startups. So, if a sample mentions an IoT pacemaker startup, it should get the IoT tag in addition to the Health tag. Tagging the data was a similar process to the previous classifier, except that this time we took special care in tagging every sample with all the relevant categories. At this point, we are ready to repeat the same experiment we did in the previous post: classifying 100 articles and seeing what happens.


How to Train Your Machine Learning Models in the Cloud – Frank's World

#artificialintelligence

Let's discuss whether you should train your models locally or in the cloud. I'll go through several dedicated GPU options, then compare three cloud options; AWS, Google Cloud, and FloydHub.

The Best Practices For Training Machine Learning Models

#artificialintelligence

Generally speaking, it is good to get your training data for at least a full week and avoid special holidays where behavior might change dramatically. It is many times a good idea to reduce your training data if you can manage to keep metrics constant and reduce training time.
