Deep Learning for Robots - TechStory
The details about this technology are available in a paper published in the journal'Science Robotics'. The task of automating warehouses can be a tricky one as many actions and decisions that come naturally to humans can be quite difficult for the robots such as the decision of how to pick up an object, the coordination of the movements of shoulders, wrists and arms to move each object from one location to another location.
Are MRI Scans Done By AI Systems Reliable?
A typical MRI scan can last 40 to 60 minutes. Additionally, clinicians have to spend up to an hour gathering sufficient data for a diagnostic MRI examination. Last year, researchers from Facebook AI and NYU Langone Health released FastMRI, a new way to use AI to accelerate the MRI scanning process. But, how good are these AI-based methods when compared to the traditional ones? Researchers at the University Of Oslo disagree with the extended usage of deep learning.
This mathematical brain model may pave the way for more human-like AI
Last week, Google Research held an online workshop on the conceptual understanding of deep learning. The workshop, which featured presentations by award-winning computer scientists and neuroscientists, discussed how new findings in deep learning and neuroscience can help create better artificial intelligence systems. While all the presentations and discussions were worth watching (and I might revisit them again in the coming weeks), one, in particular, stood out for me: A talk on word representations in the brain by Christos Papadimitriou, professor of computer science at the University of Columbia. In his presentation, Papadimitriou, a recipient of the Gรถdel Prize and Knuth Prize, discussed how our growing understanding of information-processing mechanisms in the brain might help create algorithms that are more robust in understanding and engaging in conversations. Papadimitriou presented a simple and efficient model that explains how different areas of the brain inter-communicate to solve cognitive problems.
The NLP Cypher
Microsoft's DeepSpeed continues to plot approaches to very very large language models. And now they are infiltrating the inference domain. With models containing billions and now pushing into the trillion parameter range, distributed inference is a requirement. The future of GPT-3 is global. The cat is out of the bag now.
'Smart Toilet' Uses Artificial Intelligence to Monitor Bowel Health
An artificial intelligence tool being developed by Duke scientists can be added to the standard toilet to help analyze patients' stool and give gastroenterologists the information they need to provide appropriate treatment for chronic issues such as inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). The work is being done by Duke University's Center for Water, Sanitation, Hygiene and Infectious Disease (WaSH-AID), and was presented Saturday at the virtual conference Digestive Disease Week 2021. "Typically, gastroenterologists have to rely on patient self-reported information about their stool to help determine the cause of their gastrointestinal health issues, which can be very unreliable," said Deborah Fisher, MD, associate professor of medicine at Duke University and one of the lead authors on the study. "Patients often can't remember what their stool looks like or how often they have a bowel movement, which is part of the standard monitoring process," Fisher said. "The Smart Toilet technology will allow us to gather the long-term information needed to make a more accurate and timely diagnosis of chronic gastrointestinal problems."
Day 42 - Forecasting a Time Series and Recurrent Neural Network(RNNs) - IT Consultant - SAP, Artificial Intelligence and Machine Learning
One of the most challenging parts is Forecasting a Time Series. If you agree or not, it is pretty hard to predict time-based. If you are working on a project and your task to predict delivery time using already customer-delivered dates. The customer delivery date happens delivery through one truck, and then it is a univariate time series. While in the customer delivery date based on multiple mode truck, ship, airplane, so it is multivariate time series.
The effectiveness of feature attribution methods and its correlation with automatic evaluation scores
Nguyen, Giang, Kim, Daeyoung, Nguyen, Anh
Explaining the decisions of an Artificial Intelligence (AI) model is increasingly critical in many real-world, high-stake applications. Hundreds of papers have either proposed new feature attribution methods, discussed or harnessed these tools in their work. However, despite humans being the target end-users, most attribution methods were only evaluated on proxy automatic-evaluation metrics [52, 66, 68]. In this paper, we conduct the first, large-scale user study on 320 lay and 11 expert users to shed light on the effectiveness of state-of-the-art attribution methods in assisting humans in ImageNet classification, Stanford Dogs fine-grained classification, and these two tasks but when the input image contains adversarial perturbations. We found that, in overall, feature attribution is surprisingly not more effective than showing humans nearest training-set examples. On a hard task of fine-grained dog categorization, presenting attribution maps to humans does not help, but instead hurts the performance of human-AI teams compared to AI alone. Importantly, we found automatic attribution-map evaluation measures to correlate poorly with the actual human-AI team performance. Our findings encourage the community to rigorously test their methods on the downstream human-in-the-loop applications and to rethink the existing evaluation metrics.
Explainability via Interactivity? Supporting Nonexperts' Sensemaking of Pretrained CNN by Interacting with Their Daily Surroundings
Current research on Explainable AI (XAI) heavily targets on expert users (data scientists or AI developers). However, increasing importance has been argued for making AI more understandable to nonexperts, who are expected to leverage AI techniques, but have limited knowledge about AI. We present a mobile application to support nonexperts to interactively make sense of Convolutional Neural Networks (CNN); it allows users to play with a pretrained CNN by taking pictures of their surrounding objects. We use an up-to-date XAI technique (Class Activation Map) to intuitively visualize the model's decision (the most important image regions that lead to a certain result). Deployed in a university course, this playful learning tool was found to support design students to gain vivid understandings about the capabilities and limitations of pretrained CNNs in real-world environments. Concrete examples of students' playful explorations are reported to characterize their sensemaking processes reflecting different depths of thought.
