r/MachineLearning - [D] Is finetuning on part of the evaluation dataset acceptable for publishing machine learning papers?

#artificialintelligence

I have been trying yo reproduce the results of a SOTA paper regarding object detection. I have reimplemented their method and trained on the same dataset, based on the paper, however I was not able to achieve their results on the datasets they use for evaluation, no matter what I have tried. Then I also studied their referenced papers and realised that many of them use a train-test split strategy for evaluating their models. This means that they use a part of the evaluation dataset for finetuning their already trained model and then evaluate it on the testing part of the same dataset. In the case of these papers, this fact was explicitly mentioned.


Ancestry Debuts the World's Largest Digital Archive of Searchable Online Obituaries and Death Announcements, Powered by Cutting-Edge Artificial Intelligence

#artificialintelligence

LEHI, Utah & SAN FRANCISCO--(BUSINESS WIRE)--Today, Ancestry, the global leader in family history and consumer genomics, is releasing the new Newspapers.com Obituary Collection and announcing an upgrade to its U.S. Obituary Collection, adding to what is now the world's largest, searchable digital archive of over 262 million worldwide obituaries and death announcements, containing almost 1 billion searchable family members. Obituaries are one of the most comprehensive records available about an ancestor. An obituary can act like a'starter kit' for family history -- it can include places of birth, marriage, occupation, residence, and family members, and may even suggest burial site location. One-third of Americans are unable to name all four of their grandparents,* but obituaries offer one of the easiest ways to understand recent family history and launch a journey of personal discovery.


Learning-based estimation of dielectric properties and tissue density in head models for personalized radio-frequency dosimetry

arXiv.org Machine Learning

Radio-frequency dosimetry is an important process in human safety and for compliance of related products. Recently, computational human models generated from medical images have often been used for such assessment, especially to consider the inter-variability of subjects. However, the common procedure to develop personalized models is time consuming because it involves excessive segmentation of several components that represent different biological tissues, which limits the inter-variability assessment of radiation safety based on personalized dosimetry. Deep learning methods have been shown to be a powerful approach for pattern recognition and signal analysis. Convolutional neural networks with deep architecture are proven robust for feature extraction and image mapping in several biomedical applications. In this study, we develop a learning-based approach for fast and accurate estimation of the dielectric properties and density of tissues directly from magnetic resonance images in a single shot. The smooth distribution of the dielectric properties in head models, which is realized using a process without tissue segmentation, improves the smoothness of the specific absorption rate (SAR) distribution compared with that in the commonly used procedure. The estimated SAR distributions, as well as that averaged over 10-g of tissue in a cubic shape, are found to be highly consistent with those computed using the conventional methods that employ segmentation.


Russian startup sells robot clones of real people

FOX News

Fox News Flash top headlines for Nov. 4 are here. Check out what's clicking on Foxnews.com A Russian startup is selling autonomous robots, which buyers can choose to make look like any person on Earth. "Everyone will now be able to order a robot with any appearance -- for professional or personal use. Thus, we open a huge market in service, education and entertainment. Imagine a replica of Michael Jordan selling basketball uniforms and William Shakespeare reading his own texts in a museum?" said Aleksei Iuzhakov, Chairman of the Board of Directors of Promobot, in a statement.


Logistic Regression

In the previous article, we studied Linear Regression. One thing that I believe is that if we can 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.


Transience, Replication, and the Paradox of Social Robotics

Robohub

An Art, Technology, and Culture Colloquium, co-sponsored by the Center for New Music and Audio Technologies and CITRIS People and Robots (CPAR), presented with Berkeley Arts Design as part of Arts Design Mondays. As we continue to develop social robots designed for connectedness, we struggle with paradoxes related to authenticity, transience, and replication. In this talk, I will attempt to link together 15 years of experience designing social robots with 100-year-old texts on transience, replication, and the fear of dying. Can there be meaningful relationships with robots who do not suffer natural decay? What would our families look like if we all choose to buy identical robotic family members?





Staying Relevant in an Era of Automation and AI

#artificialintelligence

The World Economic Forum, released a report in 2018, stating that, 50% of companies, will reduce their workforce, due to the efficiency of technologies, such as automation, artificial intelligence, robotics, etc., which has, significantly, reduced errors associated with humans. The report, also, stated that 75 million jobs, will be lost, in the process. Technology is, gradually, taking over and it has been projected, by economists that, Robots could take over 20 million manufacturing jobs, around the world, by 2030. It was, recently, reported that 11 years from now, 14 million robots, will be, actively, working in China, (from a 2018 study, culled from Oxford Economics in) Automation and Artificial intelligence, (AI), are gradually, taking over and this trend is noticeable, in the workplace, where there has been an exponential rise, over the past 20 years, to 2.25 million. The calculation of flight trajectories that helped spaceships into the sky was, formerly, calculated by humans, employed by NASA, (as shown in the movie, Hidden Figures), but today, automation has taken over that, relegating those employed humans, to the background.
