Interpretable Saliency Maps And Self-Supervised Learning For Generalized Zero Shot Medical Image Classification

arXiv.org Artificial Intelligence

In many real world medical image classification settings we do not have access to samples of all possible disease classes, while a robust system is expected to give high performance in recognizing novel test data. We propose a generalized zero shot learning (GZSL) method that uses self supervised learning (SSL) for: 1) selecting anchor vectors of different disease classes; and 2) training a feature generator. Our approach does not require class attribute vectors which are available for natural images but not for medical images. SSL ensures that the anchor vectors are representative of each class. SSL is also used to generate synthetic features of unseen classes. Using a simpler architecture, our method matches a state of the art SSL based GZSL method for natural images and outperforms all methods for medical images. Our method is adaptable enough to accommodate class attribute vectors when they are available for natural images.


How to effectively harness the power of digital transformation

#artificialintelligence

Key technologies – including AI, machine learning, and digital video conferencing – are proven to improve the speed, effectiveness, and efficiency of lawyers, allowing them to focus on their core business. While technology will "never be a substitute for the application of judgment and ethics that lawyers deliver to their clients and was never meant to do so, it can free up resources and time for more complex, value-added work," Smith says, noting that those that choose to ignore this fact risk finding themselves at a competitive disadvantage. Backed by a panel of leading experts including Helen Voudouris, Director of Online Product Management, LexisNexis Canada Inc.; Charles E. Gluckstein, Managing Partner, Gluckstein Lawyers; Susan Wortzman, Partner, McCarty Tetrault LLP; Al Hounsell, Senior Innovation Lawyer, Norton Rose Fulbright Canada LLP; and Natalie Munroe, Chief, Osler Works - Transactional & Legal Operations, Osler, Hoskin & Harcourt LLP, the webinar will explore the latest technological trends and identify ways to thrive in an evolving legal industry. The panel is set to tackle topics such as the role of automation and AI in driving productivity, digitizing knowledge management, and ultimately how new technologies are forcing firms to rethink how they operate. "This webinar will be an excellent opportunity for lawyers to get real-world examples from practicing lawyers on how the newest technology was implemented, how processes are managed, and the benefits to the organization," Smith says.

How to Forecast Purchase Orders for Shopify Stores Using Open-Source

#artificialintelligence

Use the open-source integrated machine learning in MindsDB and the open-source data integration platform Airbyte to forecast Shopify store metrics. With the volume of data increasing exponentially, it's critical for businesses focused on e-commerce to leverage that data as quickly and efficiently as possible. Machine learning represents a disruption to increase predictive capabilities and augment human decision making for use cases like price, assortment and supply chain optimization, inventory management, delivery management, and customer support. In this'how-to' guide, we'll provide step-by-step instructions showing you how to simply and inexpensively integrate machine learning into an existing Shopify account using Airbyte, an open-source data integration platform, and MindsDB, an open-source AutoML framework that runs on top of any database. We will assume you already have Airbyte set up via Docker.


Micro-services Architecture for Machine learning modules

#artificialintelligence

Data Acquisition and working in machine learning is a challenge. Most of the companies are collecting data of customers, sales or employees from enterprise resource planning(ERP) and customer relationship management(CRM). Each tools collects data in its own ways which provides unstructured or semi-structured or structured data for consolidation stage. There are lots of variety of data in huge scale for processing. This heterogeneity of data is a roadblock during integration and understanding meaningful insight.

Focusing on classification problems, the course uses the DecisionTreeClassifier and RandomForestClassifier methods of Python's Scikit-learn library. It prepares you for using decision trees and random forests to make predictions and understanding the predictive structure of data sets. This course is for people who want to use decision trees or random forests for prediction with Scikit-learn. This requires practical experience and the course facilitates you with Jupyter notebooks to review and practice the lessons' topics.


Crash Course: Neural Networks Part 6 -- Convolutional Neural Networks

#artificialintelligence

Computers may be smarter at some tasks than humans are, but image classification is not the case. For us, it's extremely easy to detect a plane, or a cat, or a dog. For a computer, which works only with numbers, that task is extremely difficult. For computers to be able to detect images, we had to take some inspiration from nature, from how neural cells and our eyes process images. That's how Convolutional Neural Networks were born, which are now applied to a lot more tasks than only visual recognition.


Textwash -- automated open-source text anonymisation

arXiv.org Artificial Intelligence

With the increasing digitisation of society and human communication, text data are becoming more important for research in the social and behavioural sciences (Gentzkow, Kelly, and Taddy 2019; Salganik 2019). Advances made in natural language processing (NLP) in particular have led to exciting insights derived from text data (e.g., on emotional responses to the pandemic (Kleinberg, Vegt, and Mozes 2020) or on the rhetoric around immigration in political speeches (Card et al. 2022); for an overview, see (Boyd and Schwartz 2021)). Importantly, the use of computational techniques to quantify and analyse text data has triggered a demand, especially for large datasets (often of several tens of thousands of documents) that can be harnessed for machine learning approaches (e.g., (Socher et al. 2013; Lewis et al. 2020)). That status quo of a need for larger datasets and an appetite to use text data for the study of social science phenomena has resulted in a dilemma: many of the important questions require targeted, primary data collection or access to potentially sensitive data. However, such data are hard to obtain, not because they do not exist but because sharing them is constrained by data protection regulations and ethical concerns. One potential consequence is that research activity may be biased toward topics for which suitable data is more readily available rather than those most important. One of the few viable solutions to this dilemma is automated text anonymisation; that is, the large-scale processing of text data so that individuals cannot be identified from the resulting output. Such a method would allow for the flow of sensitive data so that the staggering potential of text data can be exploited for scientific progress. With this paper and the tool it introduces, we seek to enable researchers to work with such sensitive data in a way that protects the privacy of individuals whilst retaining the usefulness of anonymised data for computational text analysis.
