#artificialintelligence

Support vector machine (SVM) is a supervised machine learning algorithm which is considered effective tool for both classification and regression problem. In a simple word, SVM tries to find a linearly separable hyperplane in order to separate members of one class from another. If SVM can not find the hyperplane for a given data set, it applies non-linear mapping to the training data and transform them to higher dimension where it searches for the optimal hyperplane. The SVM algorithm uses support vectors and margins in order to draw these hyperplanes in the training data. Since it has ability to understand the complex relation in input data by applying nonlinear mapping, it has high accuracy compare to other supervised classification algorithms (kNN, NCC..) People have been using SVM for different applications like: text data classification, image data(handwritten) recognition and more.


Natural Language Processing with TensorFlow 2 - Beginner's Course

#artificialintelligence

This course is a practical introduction to natural language processing with TensorFlow 2.0. In this tutorial you will go from having zero knowledge to writing an artificial intelligence that can compose Shakespearean prose. No prior experience with deep learning is required, though it is always helpful to have more background information. We'll use a combination of embedding layers, recurrent neural networks, and fully connected layers to perform the classification. Course Contents (01:16) Getting Started with Word Embeddings (33:25) How to Perform Sentiment Analysis on Movie Reviews (59:32) Let's Write An AI That Writes Shakespeare Course Description The basic idea behind natural language processing is that we start out with words, i.e. strings of characters, that are almost impossible for the computer to meaningfully parse.


Stargazing with Computers: What Machine Learning Can Teach Us about the Cosmos

#artificialintelligence

Gazing up at the night sky in a rural area, you'll probably see the shining moon surrounded by stars. If you're lucky, you might spot the furthest thing visible with the naked eye – the Andromeda galaxy. When the Department of Energy's (DOE) Legacy Survey of Space and Time (LSST) Camera at the National Science Foundation's Vera Rubin Observatory turns on in 2022, it will take photos of 37 billion galaxies and stars over the course of a decade. The output from this huge telescope will swamp researchers with data. In those 10 years, the LSST Camera will take 2,000 photos for each patch of the Southern Sky it covers.


All about Machine Learning

#artificialintelligence

In the previous article, we studied Artificial Intelligence, its functions, and its python implementations. In this article, we will be studying Machine Learning. One thing that I believe is that if we are able to correlate anything with us or our life, there are greater chances of understanding the concept. So I will try to explain everything by relating it to humans.


AI in Medicine: 3 Applications for Healthcare Chatbots Lionbridge AI

#artificialintelligence

There is a lot of research being done on the implementation of AI in medicine. In fact, healthcare chatbots are becoming more and more common. As chatbot technology improves our experiences with self-driving cars and virtual help desks, it's also improving health services through improved data entry, more detailed analytics, and better self-diagnosis. But exactly how can a chatbot improve your workplace? And what role does machine learning play in the process?


Audio Data Analysis Using Deep Learning with Python (Part 1) - KDnuggets

#artificialintelligence

While much of the literature and buzz on deep learning concerns computer vision and natural language processing(NLP), audio analysis -- a field that includes automatic speech recognition(ASR), digital signal processing, and music classification, tagging, and generation -- is a growing subdomain of deep learning applications. Some of the most popular and widespread machine learning systems, virtual assistants Alexa, Siri, and Google Home, are largely products built atop models that can extract information from audio signals. Audio data analysis is about analyzing and understanding audio signals captured by digital devices, with numerous applications in the enterprise, healthcare, productivity, and smart cities. Applications include customer satisfaction analysis from customer support calls, media content analysis and retrieval, medical diagnostic aids and patient monitoring, assistive technologies for people with hearing impairments, and audio analysis for public safety. In the first part of this article series, we will talk about all you need to know before getting started with the audio data analysis and extract necessary features from a sound/audio file. We will also build an Artificial Neural Network(ANN) for the music genre classification.

Semi-supervised learning with Generative Adversarial Networks - KDnuggets

#artificialintelligence

This post is part of the "superblog" that is the collective work of the participants of the GAN workshop organized by Aggregate Intellect. This post serves as a proof of work, and covers some of the concepts covered in the workshop in addition to advanced concepts pursued by the participants. The original GAN (Goodfellow, 2014) (https://arxiv.org/abs/1406.2661) is a generative model, where a neural-network is trained to generate realistic images from random noisy input data. GANs generate predicted data by exploiting a competition between two neural networks, a generator (G) and a discriminator (D), where both networks are engaged in prediction tasks. G generates "fake" images from the input data, and D compares the predicted data (output from G) to the real data with results fed back to G. The cyclical loop between G and D is repeated several times to minimize the difference between predicted and ground truth data sets and improve the performance of G, i.e., D is used to improve the performance of G.


Why this ASX artificial intelligence share rocketed 25% higher today // Motley Fool Australia

#artificialintelligence

One of the best performers on the ASX on Monday was the BrainChip Holdings Ltd (ASX: BRN) share price. The artificial intelligence company's shares rocketed 25% higher to 6.9 cents at one stage before closing the day 14.5% higher. Investors were buying the company's shares after it announced the receipt of an EAR99 classification for its Akida Neuromorphic System-on-Chip (NSoC), Akida Software Development Environment (ADE), and related technologies from the U.S. Government. The Export Administration Regulations (EAR) classification of EAR99, which BrainChip has now formally received, removes the barriers for exporting Akida to non-U.S. The EAR99 designation means the company does not require a pre-approval, or a license from the U.S. Department of Commerce, before delivering its solutions globally as part of sales and market expansion activities.
