Ideas for Alternatives to Logic in General AI Discussion

Picking things apart into definite bits is a waste of energy. AGI shouldn't have to break all curves into countless lines to make sense of them, it should only choose to do that if it's a sensible thing to do. Focusing on the self defining properties of things, could lead to universal, internally consistent predictions. A bit like geometric extensions, matching right triangles, and the like.

Internal consistency creates belief, or at least negates the necessity for suspension of disbelief, leaving us in an ideal state of undistracted observation. Its the bedrock foundation of existence, allowing us to experientially stand in every environment.

Robots have vision, and we have perception, because we are able to layer the broadly consistent, mutually indicated properties of things over the otherwise meaningless data of vision. Images are passwords for memory. The eyes are combination locks for the brain. And the brain is a picky bank, (that's picky, not piggy), just making sure... It resists cluttering itself with unintegratable or weakly bound data, because such facts appear to offer only a few, or, uncertain points of implication, to the desired utilitarian world model.

Absolute logic is very specific. You need lots of it to cover for the whole world. I feel it is better as a tool than an operating system, especially for something as broad as AGI.

Anyone have any ideas besides extending internal consistency?

Visualizing an AI model’s blind spots in Robotics News

Visualizing an AI model’s blind spots
8 November 2019, 6:30 pm

Anyone who has spent time on social media has probably noticed that GANs, or generative adversarial networks, have become remarkably good at drawing faces. They can predict what you’ll look like when you’re old and what you’d look like as a celebrity. But ask a GAN to draw scenes from the larger world and things get weird.

A new demo by the MIT-IBM Watson AI Lab reveals what a model trained on scenes of churches and monuments decides to leave out when it draws its own version of, say, the Pantheon in Paris, or the Piazza di Spagna in Rome. The larger study, Seeing What a GAN Cannot Generate, was presented at the International Conference on Computer Vision last week.

“Researchers typically focus on characterizing and improving what a machine-learning system can do — what it pays attention to, and how particular inputs lead to particular outputs,” says David Bau, a graduate student at MIT’s Department of Electrical Engineering and Computer Science and Computer Science and Artificial Science Laboratory (CSAIL). “With this work, we hope researchers will pay as much attention to characterizing the data that these systems ignore.”

In a GAN, a pair of neural networks work together to create hyper-realistic images patterned after examples they’ve been given. Bau became interested in GANs as a way of peering inside black-box neural nets to understand the reasoning behind their decisions. An earlier tool developed with his advisor, MIT Professor Antonio Torralba, and IBM researcher Hendrik Strobelt, made it possible to identify the clusters of artificial neurons responsible for organizing the image into real-world categories like doors, trees, and clouds. A related tool, GANPaint, lets amateur artists add and remove those features from photos of their own.

One day, while helping an artist use GANPaint, Bau hit on a problem. “As usual, we were chasing the numbers, trying to optimize numerical reconstruction loss to reconstruct the photo,” he says. “But my advisor has always encouraged us to look beyond the numbers and scrutinize the actual images. When we looked, the phenomenon jumped right out: People were getting dropped out selectively.”

Just as GANs and other neural nets find patterns in heaps of data, they ignore patterns, too. Bau and his colleagues trained different types of GANs on indoor and outdoor scenes. But no matter where the pictures were taken, the GANs consistently omitted important details like people, cars, signs, fountains, and pieces of furniture, even when those objects appeared prominently in the image. In one GAN reconstruction, a pair of newlyweds kissing on the steps of a church are ghosted out, leaving an eerie wedding-dress texture on the cathedral door.

“When GANs encounter objects they can’t generate, they seem to imagine what the scene would look like without them,” says Strobelt. “Sometimes people become bushes or disappear entirely into the building behind them.”

The researchers suspect that machine laziness could be to blame; although a GAN is trained to create convincing images, it may learn it's easier to focus on buildings and landscapes and skip harder-to-represent people and cars. Researchers have long known that GANs have a tendency to overlook some statistically meaningful details. But this may be the first study to show that state-of-the-art GANs can systematically omit entire classes of objects within an image.

An AI that drops some objects from its representations may achieve its numerical goals while missing the details most important to us humans, says Bau. As engineers turn to GANs to generate synthetic images to train automated systems like self-driving cars, there’s a danger that people, signs, and other critical information could be dropped without humans realizing. It shows why model performance shouldn’t be measured by accuracy alone, says Bau. “We need to understand what the networks are and aren’t doing to make sure they are making the choices we want them to make.”

Joining Bau on the study are Jun-Yan Zhu, Jonas Wulff, William Peebles, and Torralba, of MIT; Strobelt of IBM; and Bolei Zhou of the Chinese University of Hong Kong.

Driving toward a healthier planet in Robotics News

Driving toward a healthier planet
7 November 2019, 6:20 pm

With 100 million Toyota vehicles on the planet emitting greenhouse gases at a rate roughly comparable to those of France, the Toyota Motor Corporation has set a goal of reducing all tailpipe emissions by 90 percent by 2050, according to Brian Storey, who directs the Toyota Research Institute (TRI) Accelerated Materials Design and Discovery program from its Kendall Square office in Cambridge, Massachusetts. He gave the keynote address at the MIT Materials Research Laboratory's Materials Day Symposium on Oct. 9.

“A rapid shift from the traditional vehicle to electric vehicles has started,” Storey says. “And we want to enable that to happen at a faster pace.”

“Our role at TRI is to develop tools for accelerating the development of emissions-free vehicles,” Storey said. He added that machine learning is helping to speed up those innovations, but the challenges are very great, so his team has to be a little humble about what it can actually accomplish.

Electrification is just one of four “disrupters” to the automotive industry, which are often abbreviated CASE (connected, autonomous, shared, electric). “It’s a disrupter to the industry because Toyota has decades of experience of optimizing the combustion engine,” Storey said. “We know how to do it; it’s reliable; it’s affordable; it lasts forever. Really, the heart of the Toyota brand is the quality of the combustion engine and transmission.”

Storey stated that as society shifts toward electrification — battery or fuel cell vehicles — new capability, technology, and know-how is needed. Storey says “while Toyota has a lot of experience in these areas, we still need to move faster if we are going to make this kind of transition.”

To help with that acceleration, Toyota Research Institute is providing $10 million a year to support research of approximately 125 professors, postdocs, and graduate students at 10 academic institutions. About $2 million a year of that research is being done at MIT. Storey is also a professor of mechanical engineering at Olin College of Engineering.

For example, the Battery Evaluation and Early Prediction (BEEP) project, which is a TRI collaboration with MIT and Stanford University, aims to expand the value of lithium-based battery systems. In experiments, many batteries are charged and discharged at the same time. “From that data alone, the charge and discharge data, we can extract features. It’s super practical because we get the data. We extract features from the data, and we can correlate those features with lifetime,” Storey explained.

The traditional way of testing whether a battery is going to last for a thousand cycles is to cycle it for a thousand times. Storey noted that if each cycle takes one hour, one battery requires 1,000 hours of testing. “What we want to do is bring that time way back, and so our goal is to able to do it in five — to cycle five times and get a good estimate of what the battery’s lifetime would be at 1,000 cycles, doing it purely from data,” Storey said.

Published results in Nature Energy in March 2019 show just a 4.9 percent test error using data in classifying lithium-ion batteries from the first five charge/discharge cycles.

“This is a nice capability because it actually allows acceleration in testing,” Storey noted. “It’s using machine learning, but it’s really using it at the device scale, the ‘as-manufactured’ battery.”

The cloud-based battery evaluation software system allows TRI to collaborate easily with colleagues at MIT, Stanford, and Toyota’s home base in Japan, he said.

Program researchers operate it in a closed-loop, semi-autonomous way, where the computer decides and executes the next-best experiment. The system finds charging policies that are better than ones that have been published in the literature, and it finds them rapidly. “The key to this is the early prediction model, because if we want to predict the lifetime, we don’t have to do the whole test.” Storey added that the closed-loop testing “pulls the scientist up a level in terms of what questions they can ask.”

TRI would like to use this closed-loop battery evaluation system to optimize the first charge/discharge cycle a battery goes through, which is called formation cycling. “It’s like caring for the battery when it’s a baby,” Storey explained. “How you do those first cycles actually sets it up for the rest of its life. It’s a real black art, and how do you optimize this process?”

TRI’s long-term goal is to improve battery durability so that, from the consumer point of view, the battery capacity never goes down. Storey emphasized “we want the battery in the car to just last forever.”

Storey notes TRI is also conducting two other research projects, AI-Assisted Catalysis Experimentation (ACE) with CalTech to improve catalysts for fuel cell vehicles such as Toyota’s Mirai, and a materials synthesis project, mostly within TRI, to use machine learning to identify whether or not the new materials predicted on the computer are likely to be synthesizable.

For the materials synthesis project, TRI began with the phase diagrams of materials. “You build up a network of every material you’ve got in the computational database and look at features of the network. Believing that somehow those materials are connected to other materials through the relationship in this network provides a prediction of synthesizability,” Storey explained. “The way you can train the algorithm is by looking in the historical record of when certain materials were synthesized. You can virtually roll the clock back, pretending to know only what you knew in 1980, and use that to train your algorithm.” A report on the materials synthesis network was published in May in Nature Communications.

TRI is collaborating with Lawrence Berkeley National Laboratory (LBNL) and MIT Professor Martin Z. Bazant on a project that couples highly detailed mechanics of battery particles revealed through 4D scanning tunneling electron microscopy with a continuum model that captures larger-scale materials properties. “This program figures out the reaction kinetics and thermodynamics at a continuum scale, which is otherwise unknown,” Storey said.

“We’re putting our software tools online, so over the coming year many of these tools will start becoming available,” Storey explained. Hosted by LBNL, the Propnet materials database is already accessible to internal collaborators. Matscholar is accessible through GitHub. Both projects were funded by TRI.

“Our dream, which is a work in progress, is to have a system architecture that overlies all these projects and can start to tie them together,” Storey said. “We are creating a system that’s built for machine learning from the start, allows for diverse data, allows for systems and atom-scale measurements, and is capable of this idea of AI-driven feedback and autonomy. The idea is that you launch the system and it runs on its own, and everything lives in the cloud to enable collaboration.”

Chatbots and Conversational UI Development

Chatbots and Conversational UI Development in Books

Conversation as an interface is the best way for machines to interact with us using the universally accepted human tool that is language. Chatbots and voice user interfaces are two flavors of conversational UIs. Chatbots are real-time, data-driven answer engines that talk in natural language and are context-aware. Voice user interfaces are driven by voice and can understand and respond to users using speech. This book covers both types of conversational UIs by leveraging APIs from multiple platforms. We'll take a project-based approach to understand how these UIs are built and the best use cases for deploying them.

Build over 8 chatbots and conversational user interfaces with leading tools such as Chatfuel, Dialogflow, Microsoft Bot Framework, Twilio, Alexa Skills, and Google Actions and deploying them on channels like Facebook Messenger, Amazon Alexa and Google Home.
