Nice layout and looking smart, well done.

I see you also made it responsive for mobile, that's working well and Google will like it.

I love chatbots because they are fun, I tolerate robots but enough is enough how much privacy do we have to lose? It makes me want to grab a bow and arrow a sleeping bag  a tent and go live in the wilderness. I know we don't have much left but i don't want some house telling me when I have to take my meds or that my blood pressure is to hight, I want to be forced to get up and turn off those lights. When you get older if you don't keep exercising and moving you start losing the ability. So all this convenance could mean a slow living death for the elderly. Noooo thanks.

A step toward personalized, automated smart homes
17 October 2018, 5:00 am

Developing automated systems that track occupants and self-adapt to their preferences is a major next step for the future of smart homes. When you walk into a room, for instance, a system could set to your preferred temperature. Or when you sit on the couch, a system could instantly flick the television to your favorite channel.

But enabling a home system to recognize occupants as they move around the house is a more complex problem. Recently, systems have been built that localize humans by measuring the reflections of wireless signals off their bodies. But these systems can’t identify the individuals. Other systems can identify people, but only if they’re always carrying their mobile devices. Both systems also rely on tracking signals that could be weak or get blocked by various structures.

MIT researchers have built a system that takes a step toward fully automated smart home by identifying occupants, even when they’re not carrying mobile devices. The system, called Duet, uses reflected wireless signals to localize individuals. But it also incorporates algorithms that ping nearby mobile devices to predict the individuals’ identities, based on who last used the device and their predicted movement trajectory. It also uses logic to figure out who’s who, even in signal-denied areas.

“Smart homes are still based on explicit input from apps or telling Alexa to do something. Ideally, we want homes to be more reactive to what we do, to adapt to us,” says Deepak Vasisht, a PhD student in MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and lead author on a paper describing the system that was presented at last week’s Ubicomp conference. “If you enable location awareness and identification awareness for smart homes, you could do this automatically. Your home knows it’s you walking, and where you’re walking, and it can update itself.”

Experiments done in a two-bedroom apartment with four people and an office with nine people, over two weeks, showed the system can identify individuals with 96 percent and 94 percent accuracy, respectively, including when people weren’t carrying their smartphones or were in blocked areas.

But the system isn’t just novelty. Duet could potentially be used to recognize intruders or ensure visitors don’t enter private areas of your home. Moreover, Vasisht says, the system could capture behavioral-analytics insights for health care applications. Someone suffering from depression, for instance, may move around more or less, depending on how they’re feeling on any given day. Such information, collected over time, could be valuable for monitoring and treatment.

“In behavioral studies, you care about how people are moving over time and how people are behaving,” Vasisht says. “All those questions can be answered by getting information on people’s locations and how they’re moving.”

The researchers envision that their system would be used with explicit consent from anyone who would be identified and tracked with Duet. If needed, they could also develop an app for users to grant or revoke Duet’s access to their location information at any time, Vasisht adds.

Co-authors on the paper are: Dina Katabi, the Andrew and Erna Viterbi Professor of Electrical Engineering and Computer Science; former CSAIL researcher Anubhav Jain ’16; and CSAIL PhD students Chen-Yu Hsu and Zachary Kabelac.

Tracking and identification

Duet is a wireless sensor installed on a wall that’s about a foot and a half squared. It incorporates a floor map with annotated areas, such as the bedroom, kitchen, bed, and living room couch. It also collects identification tags from the occupants’ phones.

The system builds upon a device-based localization system built by Vasisht, Katabi, and other researchers that tracks individuals within tens of centimeters, based on wireless signal reflections from their devices. It does so by using a central node to calculate the time it takes the signals to hit a person’s device and travel back. In experiments, the system was able to pinpoint where people were in a two-bedroom apartment and in a café.

The system, however, relied on people carrying mobile devices. “But in building [Duet] we realized, at home you don’t always carry your phone,” Vasisht says. “Most people leave devices on desks or tables, and walk around the house.”

The researchers combined their device-based localization with a device-free tracking system, called WiTrack, developed by Katabi and other CSAIL researchers, that localizes people by measuring the reflections of wireless signals off their bodies.

Duet locates a smartphone and correlates its movement with individual movement captured by the device-free localization. If both are moving in tightly correlated trajectories, the system pairs the device with the individual and, therefore, knows the identity of the individual.

To ensure Duet knows someone’s identity when they’re away from their device, the researchers designed the system to capture the power profile of the signal received from the phone when it’s used. That profile changes, depending on the orientation of the signal, and that change be mapped to an individual’s trajectory to identify them. For example, when a phone is used and then put down, the system will capture the initial power profile. Then it will estimate how the power profile would look if it were still being carried along a path by a nearby moving individual. The closer the changing power profile correlates to the moving individual’s path, the more likely it is that individual owns the phone.

Logical thinking

One final issue is that structures such as bathroom tiles, television screens, mirrors, and various metal equipment can block signals.

To compensate for that, the researchers incorporated probabilistic algorithms to apply logical reasoning to localization. To do so, they designed the system to recognize entrance and exit boundaries of specific spaces in the home, such as doors to each room, the bedside, and the side of a couch. At any moment, the system will recognize the most likely identity for each individual in each boundary. It then infers who is who by process of elimination.

Suppose an apartment has two occupants: Alisha and Betsy. Duet sees Alisha and Betsy walk into the living room, by pairing their smartphone motion with their movement trajectories. Both then leave their phones on a nearby coffee table to charge — Betsy goes into the bedroom to nap; Alisha stays on the couch to watch television. Duet infers that Betsy has entered the bed boundary and didn’t exit, so must be on the bed. After a while, Alisha and Betsy move into, say, the kitchen — and the signal drops. Duet reasons that two people are in the kitchen, but it doesn’t know their identities. When Betsy returns to the living room and picks up her phone, however, the system automatically re-tags the individual as Betsy. By process of elimination, the other person still in the kitchen is Alisha.

“There are blind spots in homes where systems won’t work. But, because you have logical framework, you can make these inferences,” Vasisht says.

“Duet takes a smart approach of combining the location of different devices and associating it to humans, and leverages device-free localization techniques for localizing humans,” says Ranveer Chandra, a principal researcher at Microsoft, who was not involved in the work. “Accurately determining the location of all residents in a home has the potential to significantly enhance the in-home experience of users. … The home assistant can personalize the responses based on who all are around it; the temperature can be automatically controlled based on personal preferences, thereby resulting in energy savings. Future robots in the home could be more intelligent if they knew who was where in the house. The potential is endless.”

Next, the researchers aim for long-term deployments of Duet in more spaces and to provide high-level analytic services for applications such as health monitoring and responsive smart homes.

Any cat lover will tell you that they are far more intelligent then scientists give them credit for. They are little scientists themselves and learn to do amazing things. Mine decided my halloween decoration was his own person human toy. lol lol.
General Project Discussion / redoing my site
« Last post by DemonRaven on October 21, 2018, 08:12:23 am »
I finally gave up and decided to redo my site and making it a tiny more streamline and modern. I am still stuck in the I want to code it by hand though and it seems like all the web hosts want to toss ready made templates at you. I am fussy I like it done a certain way. I am having to move it back to a paid site sigh because my free one is complaining about the bots and downloads now. A new guy bought the place so he is doing it different. He is also being a jerk and trying to keep me from getting my images. He managed to freeze them.  However i am a bit more talented then he is Luckily lol. IT will be a while before it is done and it is a work in progress but two of the pages are pretty much done to my satisfaction. I wish i could figure out how to make the menu look the same as the rest and there is a annoying active  x control that I accidently added opps it makes the page poof white.for a sec. sooner or later i will figure out what i did wrong. I learn best by frustrating myself and just digging in and creating. and are done if you are curious

Wherever you end up 50 or more years from now, look at where you are and think back to this time. Do the comparison. How's that new life working out for you? quiet, one of the robot guards are coming...
Pulls out bazooka BOOM. Opps I took out a building too sh*t.

General AI Discussion / Re: ETHICS
« Last post by DemonRaven on October 21, 2018, 07:47:43 am »
If we create an AGI, we need to make sure it behaves well. I tried to distill ethics to the basic principles. Let me know if I've forgotten to include anything important.

ETHICS : Do not attempt nor accomplish actions which do unjust harm to other life. Attempt and accomplish actions which aid other life.

The initial and most important steps of AGI development will definitely be based on learning from demonstrations where the AI will observe the behavior of humans, learn from it and (hopefully eventually) try to reproduce it. This means that the ethics of  humans will have a high impact on the ethics of future AGI. However, at this point and for this context I am not really sure whether this good, bad, neutral or anything else...

lol are you really sure you want a AI/Robot to imitate a human lol Microsoft did not have much luck on that lol lol

But all animals DON'T!

As Korrelan mentioned, only the vast majority of animals, especially those with higher intelligence will be able to recognize themselves in a mirror.

Some kittens, dogs or birds will see their reflection in a mirror and practically (if not) attack it, thinking it is another of its kind which might pose to be a threat.

It takes a special intelligence to recognize one's own reflection and recognize that the owner is the one looking at it.
Elephants, chimps, dolphins, and this cat, perhaps there are others but that is the gist of it.

Several animals exhibit very interesting problem-solving skills but this is different. This is about "self".
