Meet YU’s Incoming Class – Yu News (blog)

Yehudah Goldfeder of Monsey, New York: Intrigued by Artificial Intelligence

In the coming weeks, Yeshiva University will welcome hundreds of new students to its undergraduate campuses from across the United States and countries around the world.Meet the incoming class as they share in their own words what excites them about beginning their academic journeys at YU at this yearsOrientation.

Where are you from?

I am from Monsey, New York.

Why did you decide to come to Yeshiva University?

Many factors contributed to my decision. I am the youngest in my family, and I have four older siblings, all of whom attended Stern College for Women or Yeshiva College, as did my father. My mother is a graduate of YUs high school for girls as well. Thank God, all of them have successful careers in their various fields. Those who went to grad school all got in to the school of their choice.

But to be honest, none of that is the real reason Im going to YU. I feel that it is important to forge ones own path in life. In truth, the reason I chose YU is because it was the best option available. I am fully committed to living an authentic Torah lifestyle, with all that it entails, while at the same time being an active and important participant in the modern world. I think that in YU Ill be able to maintain a real, rigorous learning schedule. Additionally, I am firmly convinced of the importance, perhaps necessity, of having a bona fide mentor to guide me along my path, and YU boasts a wide array of roshei yeshiva and rebbeim who can cater to a large spectrum of students individual needs. I still want my secular education to be a priority as well, and I think that YU will be able to cater well to this dual need.

What are you looking forward to at YU?

I plan on studying computer science, which has long been a passion of mine. It started as a hobby when I was eight or nine, and developed over time into one of my favorite subjects. I particularly have an interest in artificial intelligence that is getting machines to behave like intelligent, rational agents. Ive done a lot of self-study on that topic, like programming a chess engine (that plays better than I do) in C++ and learning the basics behind machine learning and artificial neural networks. I was specifically motivated by the groundbreaking Alphago, the first program to do the impossible and beat an elite Go player.However, computer science is a wide field and I find many topics in it interesting and worthy of exploration. I am very excited to finally get a formal education so that I can further my knowledge and my goals.

I also enjoy math and look forward to furthering my education there too. Writing has always been a hobby of mine, and I have written several large manuscripts of novels. Ive always felt that I have potential to be a good writer, and I am excited to explore that subject as well. The extracurriculars also seem exciting. I havent decided on exactly what Ill do (although I have some ideas in mind), but I am certain that aside from studying, Ill have plenty of fun.

As Ive mentioned, as well, I am very excited to benefit from the rebbeim here. Having a kesher, a relationship, with a rebbi where I can ask questions outside of the gemara, whether on general hashkafa or my personal life, is very important to me. I am also part of the MasmidimHonors Program, and it is my hope that those in charge of the program will guide me to be the best Jew I can be. I would love to learn as much as I can, in all topics related to yahadut[Judaism].

What are you passionate about?

I enjoy reading a lot. There are various genres I read, although Ill admit I have a soft spot for epic fantasy. I also enjoy building things with my hands, such as wood models, and I have a brown belt in karate.

What are you hoping to do professionally?

Hard to say exactly. Obviously I feel it will be computer-related, but to be totally open and honest, that could change in three years from now. I could see myself in many different roles, which is one of the reasons I am so happy to explore different topics.

See bots run – The Hub at Johns Hopkins

By Catherine Graham

The player approaches the ball and prepares to score the goal. The crowd waits anxiously.

The player isn’t David Beckham or Cristiano Ronaldoit’s a small, blue EduMIP mobile robot. And it’s not the final moments of the World Cup. Instead, it’s a robotics demonstration in a lab on the campus of Johns Hopkins University Whiting School of Engineering.

While the stakes aren’t quite as high, these demonstrations are still nerve-wracking for students in the graduate-level Robot Systems Programming course.

“Not all the demos work out perfectly, and that’s OK. But you have to try,” said Louis Whitcomb, chair of the Department of Mechanical Engineering who created and has taught the course for the past four years. Despite many hours of planning, building, and testing the robots, students know that at any given moment, things may not go as planned.

Students in his course spent the last five weeks of the spring semester building and programming their own independent robotic projects. Whitcomb provides equipment and instruction but encourages students to experiment and set their own project goals. On Monday and Tuesday, 12 student teams demonstrated their robots in labs across the Homewood campus.

Students Andrew Dykman, Saurabh Singh, and Allen Jiang built a system that allows five separate EduMIP robots to communicate, move into a swarm formation, and work together to achieve complex tasks. During the demonstration, the team explained how, with some fine tuning, this technology could have many real-world applications.

“Take, for example, self-driving cars,” Dykman said. “If every car on the road is running automated systems and communicating with cars around it, we could move cars at a higher speed without crashing, or reduce traffic jams by eliminating human errors.”

For their project, students Kevin Yee and Nicole Ortega decided to take a favorite pastime to the next level.

“We know people already like to play chess against a computer, so we wanted to see what it’d be like to play chess against a robot,” Yee said.

The pair created a platform that allows users to play chess against a chess engine on a physical board. They built a mobile robot, equipped with an end effector, that can make strategic moves and place chess pieces on target locations. According to Ortega, the robot usually wins.

Other demos included robots that can locate a soccer ball and score goals, a ball-catching robotic arm, a “self-standing” robot that can leap across obstacles, a team of robots that can map a location, and autonomous quadcoptors.

The Robot Systems Programming course gives students the tools to create their own unique vision of what a robot can do. Some will graduate next week and enter the field, and some will continue graduate work in robotics. Either way, Whitcomb said he hopes his students will use these skills to continue to explore what’s possible in robotics.

“This course is intended to be a capstone experience for our advanced undergraduate and graduate robotics students,” he said, “in which they use and apply the knowledge they have learned in the mathematics, engineering, and physics of robotics to develop real-world robots that can sense and interact with people and the world.”

Can You Solve This Chess Puzzle That AI Software Can’t? – Interesting Engineering

Back in 1997,Garry Kasparov, a chess grandmaster as the world knows him, was defeated byIBMs Deep Blue artificial intelligence (AI) computer. It was down hill from there for human chess players all over the world as AI machines began improving at an alarming rate.

[Image Source:Pixabay]

Komodo, a chess engine with an Elo rating of 3304 (450 points higher than Kasparov) was next in line to prove that computers are far superior when it comes to head to head chess matches.

This is partially due to Moores Law, which states that the number of transistors per square inch on integrated circuit board doubles year on year, allowing for greater computational power. This statement was originally made byIntel co-founder Gordon Moore in 1965 and holds up today.

Another reason for the demise of human chess players is the softwares ability to brute force its way through millions of possible scenarios in a matter of seconds. But recently, one scenario has these computers stumped.

[Image Source: Lichess]

The scenarioconsists of a chess board layout as per the image above. The human player is required todefeat or draw against the computer while playing as whites.(You can play an online simulation of the chess puzzle here.)

The puzzle, released by the Penrose Institute, was recently devised in order to study human consciousness through physics. The Penrose Institute founder, Sir Roger Penrose, Emeritus Professor at the Mathematical Institute of Oxford, devised the puzzle to distinguish between human and artificial intelligence machines. The puzzle is said to be solvable by humans but not by AI software.

If you put this puzzle into a chess computer it just assumes a black win because of the number of pieces and positions, but a human will look at this and know quickly that is not the case, said Sir Roger.

Penrose shared the World Prize in physics with Professor Stephen Hawking in 1988 for his work on black hole singularities.

Co-Founder and Director of the Penrose Institute, James Tagg said We plugged it into Fritz, the standard practice computer for chess players, which did three-quarters of a billion calculations, 20 moves ahead,

It says that one-side or the other wins. But, Tagg continued, the answer that it gives is wrong.

What makes the puzzle so unique, is the odd choice of a third bishop. This forces the AI software out of its comfort zone, with an endless amount of possible moves. It also begs the question, is it actually possible to get to this scenario?

Those who figure out the puzzle can send their answers to Penrose to be entered in to win the professors latest book. Goodluck!

Chess Engines – Tim Mann

Are you writing a chess engine that you want to have work with XBoard and/or WinBoard? Are you writing a chess user interface or other tool and want it to work with the same engines that work with XBoard and WinBoard? Here are some pointers.

First, read the Chess Engine Communication Protocol document, which describes the protocol that XBoard and WinBoard use to communicate with engines. This document is also included with the XBoard/WinBoard source code, available through the GNU XBoard project page.

Second, go to the WinBoard Forum and ask the folks there for help and advice if you need it.

There are literally hundreds of chess engines (programs that play chess) that work with XBoard and/or WinBoard. I gave up on keeping an updated list years ago, and the old list that used to be here contained so many dead links that I have deleted it.

Some good places to find out about chess engines that you can use include Leo Dijksman’s web site and the WinBoard Forum. Also see the other links on my Chess Web Sites page.
