Machine learning to create some of the new mathematical conjectures – Techiexpert.com – TechiExpert.com

Creating new mathematical conjectures and theorems needs a complex approach which requires three factors that are:

At DeepMind, a UK-based artificial intelligence laboratory, researchers in collaboration with mathematicians at the University of Oxford, UK, and University of Sydney, Australia, respectively. The researchers over there have made an important breakthrough by using machine learning to highlight the mathematical connections that human counterparts miss.

Into the technology behind DeepMind

In fascination with the way humans usually used to think and human-based intelligence has long caught the image of computer scientists. Human intelligence has en-sharpened the digital modern world, thus allow us to learn, create, communicate and develop by our own self-awareness.

Since 2010, researchers and developers at the DeepMind team have been trying to solve intelligence-based problems, developing problem-solving systems that are an Artificial General Intelligence (AGI).

In order to perform, DeepMind takes an interdisciplinary approach that commits machine learning and neuroscience, philosophy, mathematics, engineering, simulation, and computing infrastructure together.

The company has already made significant breakthroughs with its machine learning and AI systems, for example, the AlphaGo program, which was the first AI to beat a human professional Go player.

Thinking DeepMaths

The work developed by the DeepMind team says that mathematicians can benefit from machine learning tools to sharpen up and enhance up their intuition where complex mathematical objects and their relationships are highly concerned.

Initially, the project was focused on identifying mathematical conjectures and theorems that DeepMinds technology could deal with, but ultimately it is all dependent upon probability as opposed to absolute certainty.

However, when dealing with large sets of information, the researchers tried to apply their own intuition that the AI could detect the signal relationships between mathematical objects. Afterward, the mathematicians could then apply their own conjecture to the relationships to make them an absolute certainty.

Tied up in Knots

Machine learning requires several amounts of data in order to complete the task efficiently and effectively. So the researchers tied knots as their starting point, calculating invariants.

DeepMinds AI software was assumed to work on two separate components of knot theory; algebraic and geometric. The team then used the program to seek relationships between straightforward and complex correlations as well as subtle and unintuitive ones.

The leads presenting the most promising data were then directly handed over to human mathematicians for analysis and refinement.

The DeepMind team believes that mathematics can release the benefits from methodology and technology as an effective mechanism that could see the widespread application of machine learning in mathematics. Thus, this strengthens the relationship between methodology and technology.

Comparative Analysis Between Machine Learning Algorithms and Conventional Regression in Predicting the Prognosis of Patients with Basilar…

This article was originally published here

Turk Neurosurg. 2021 Nov 10. doi: 10.5137/1019-5149.JTN.36068-21.3. Online ahead of print.

ABSTRACT

AIM: We sought to identify predictors of basilar invagination (BI) prognosis and compare diagnostic properties between logistic modeling and machine learning methods.

MATERIAL AND METHODS: We conducted a single-center retrospective study. Patients at our hospital who met the inclusion and exclusion criteria were identified between August 2015 and August 2020 for inclusion. Candidate predictors, such as demographics, clinical scores, radiographic parameters, and outcome, were included. The primary outcome was the prognosis evaluated by the change in patient-reported Japanese orthopaedic association (PRO-JOA) score. Conventional logistic regression models and machine learning algorithms were implemented. Models were compared, considering the area under the curve (AUC), sensitivity, specificity, positive and negative predictive values, and calibration curve.

RESULTS: Overall, the machine learning algorithms and traditional logistic regression models performed similarly. The postoperative cervicomedullary angle, head-neck flexion angle (HNFA), atlantodental interval, postoperative clivo-axial angle, age, postoperative clivus slope, postoperative cranial incidence, weight, postoperative HNFA, and postoperative Boogaards angle (BoA) were identified as important predictors for BI prognosis. Among the surveyed radiographic parameters, postoperative BoA was the most important predictor of BI prognosis. In the validation dataset, the bagged trees model performed best (AUC, 0.90).

CONCLUSION: Through machine learning, we have demonstrated predictors of BI prognosis. Machine learning methods did not provide too many advantages over logistic regression in predicting BI prognosis but remain promising.

Amazon awards grant to UI researchers to decrease discrimination in AI algorithms – UI The Daily Iowan

A team of University of Iowa researchers received $800,000 from Amazon and the National Science Foundation to limit the discriminatory effects of machine learning algorithms.

University of Iowa researcher Tianbao Yang seats at his desk where he works on AI research on Friday, Aril 8, 2022.

University of Iowa researchers are examining discriminative qualities of artificial intelligence and machine learning models, which are likely to be unfair against ones race, gender, or other characteristics based on patterns of data.

A University of Iowa research team received an $800,000 grant funded jointly by the National Science Foundation and Amazon to decrease the possibility of discrimination through machine learning algorithms.

The three-year grant is split between the UI and Louisiana State University.

According to Microsoft, machine learning models are files trained to recognize specific types of patterns.

Qihang Lin, a UI associate professor in the department of business analytics and grant co-investigator, said his team wants to make machine learning models fairer without sacrificing an algorithms accuracy.

RELATED: UI professor uses machine learning to indicate a body shape-income relationship

People nowadays in [the] academic field ladder, if you want to enforce fairness in your machine learning outcome, you have to sacrifice the accuracy, Lin said. We somehow agree with that, but we want to come up with an approach that [does] trade-off more efficiently.

Lin said discrimination created by machine learning algorithms is seen disproportionately predicting rates of recidivism a convicted criminals tendency to re-offend for different social groups.

For instance, lets say we look at in U.S. courts, they use a software to predict what is the chance of recidivism of a convicted criminal and they realize that that software, that tool they use, is biased because they predicted a higher risk of recidivism of African Americans compared to their actual risk of recidivism, Lin said.

Tianbao Yang, a UI associate professor of computer science and grant principal investigator, said the team proposed a collaboration with Netflix to encourage fairness in the process of recommending shows or films to users.

Here we also want to be fair in terms of, for example, users gender, users race, we want to be fair, Yang said. Were also collaborating with them to use our developed solutions.

Another instance of machine learning algorithm unfairness comes in determining what neighborhoods to allocate medical resources, Lin said.

RELATED: UI College of Engineering uses artificial-intelligence to solve problems across campus

In this process, Lin said the health of a neighborhood is determined by examining household spending on medical expenses. Healthy neighborhoods are allocated more resources, creating a bias against lower income neighborhoods that may spend less on medical resources, Lin said.

Theres a bad cycle that kind of reinforces the knowledge the machines mistakenly have about the relationship between the income, medical expense in the house, and the health, Lin said.

Yao Yao, UI third-year doctoral candidate in the department of mathematics, is conducting various experiments for the research team.

She said the importance of the groups focus is that they are researching more than simply reducing errors in machine learning algorithm predictions.

Previously, people only focus on how to minimize the error but most time we know that the machine learning, the AI will cause some discrimination, Yao said. So, its very important because we focus on fairness.
