When I want to understand a problem, I'll often use different sources. I'll read different textbooks, blog posts, research papers and ask the same question to different people. The differences in the solutions are almost always illuminating.
I feel the same way about AIs. Sometimes, I don't want to ask *THE* AI...I want to ask a bunch of them. They'll have different strengths and weaknesses..different personalities if you want to think of it that way.
I've been playing with the AI chat arena and there really is a lot of difference between the answers returned by different models. https://lmarena.ai/?arena
I think it would be great if the MATLAB Chat playgroundwere to allow the user to change which AI they were talking with.
What does everyone else think?

Some years ago I installed a IOBridge IO-204 device from https://iobridge.com/
This was used to remotely control and monitor heating of a building trough the "ioApp" or trough the widgets on their webpage.
Seems like the support for the app and the IObridge webpage (including widgets) is discontinued and the webpage now links to ThingSpeak without any further information.
I cannot find any information about using ThingSpeak to communicate and control an ioBridge IO-204 device?
If it is possible I would really appreciate some help getting starter to do the setup.
Thanks in advance.

We are excited to unveil the ‘Open in MATLAB Online from File Exchange’ feature, which offers MATLAB users a new way to open File Exchange content!
Previously, to experiment with File Exchange code, you were required to download the file and execute it in MATLAB. But now, there's a quicker and easier way to explore the code!
You will find the ‘Open in MATLAB Online’ button next to the ‘Download’ button (see the screenshot below). A simple click transports you directly into the MATLAB Online workflow. It's that straightforward and effortless.
We strongly encourage you to try this new feature. Please share your questions, comments, or ideas by responding to this post!
Hello Community!
We are working on a new translation experience for the MathWorks website and products. The goal is to make it easy for people to see content in the best language for them.
Step 1 is learning from those of you who use another language instead of, or in addition to English. If this sounds like you, we'd love your response to a brief survey.
Feel free to comment here as well. Thanks in advance!
We've released an open-source implementation of STIPA (Speech Transmission Index for Public Address) on GitHub!
What is STIPA?
Speech Transmission Index is a metric designed to assess the quality of speech transmission through a communication channel. It quantifies the intelligibility of speech signals based on amplitude modulations, providing a standardized measure crucial for evaluating public address systems and communication equipment. STIPA is a version of STI using a simplified measurement method and only one test signal.
Quality Representation:
STI values range from 0 to 1, categorizing speech transmission quality from bad to excellent. The raw STI score can be transformed into the likelihood of intelligibility of syllables, words, and sentences being comprehended.
Verification Tests:
To ensure reliability, we've conducted verification tests according to the IEC 60286-16 standard. Download the test signals and run the stipaVerificationTests.m script from our GitHub repository.
Control Measurements:
We've performed comparative measurements in a university auditorium, showcasing the validity of our implementation.
License:
Our STIPA implementation is distributed under the GNU General Public License 3, reflecting our commitment to open-source collaboration.
I have been finding the AI Chat Playground very useful for daily MATLAB use. In particular it has been very useful for me in basically replacing or supplementing dives into MATLAB documentation. The documentation for MATLAB is in my experience uniformly excellent and thorough but it is sometimes lengthy and hard to parse and the AI Chat is a great one stop shop for many questions I have. However, I would find it very useful if the AI Chat could answer my queries and then also supply a link directly to the documentation. E.g. a box at the bottom of the answer that is basically
"Here is the documentation on the functions AI Chat referred to in this response"
could be neat.

Buenas noches. Tengo una estación meteorológica contruida con Arduino, desde hace 4 años y funcionando perfectamente, y veo los datos mediante ThingSpeak. El problema es el que se ve en la imagen:
La méteo, gestionada por una placa Arduino Wemos D1 Mini Pro, una placa solar, una batería y un sensor BME280, funciona cada hora. És decir, está hivernando y cada hora, durante un breve lapso de tiempo, despierta y emite los datos. ThingSpeak los envía a mi ordenador. El problema es que durante 4 años, ha estado enviando, cada hora, una sola lectura de los datos, però ahora envía dos o tres datos con minutos de diferencia, con lo que la lectura y procesamiento de estos datos, se ha vuelto inestable.
No se si es debido a una reinstalación del sistema operativo, debido a un problema que he tenido con el SO, o a qué, pero quisiera volver a ver los datos de forma única, un solo dato cada hora. He sustituido la placa Arduino por otra, pero el problema persiste sin solucionarse, con lo que deduzco que posoblemente deba atribuirse al programa ThingSpeak.
Sería posible solucionar este problema? Hay alguna manera de acceder a modificar, específicamente, esta configuración para volver a mostrar únicamente una lectura por hora?
Gracias por la atención y la ayuda
Salu2 cordiales

I'd like to give someone quick access to a private channel via a URL. Basically, I'd like to place a QR code sticker on the device so that any time they want, they can quickly check out how the device data is trending by pointing their cell phone camera at the QR code and clicking. Ez-peezie. This works with a public channel because no authentication is required,
Is there a way to do this with a private channel? I was hoping I could add their email address to the sharing tab for the channel and then, after they had logged into Thingspeak on their phone with their own account, perhaps their browser state would be retained and when the camera launched a browser tab with the url, it would work. But alas, I've probably over-simplied the credentials aspect betwen the camera app and the brower app. At least it doesn't seem to work with Safari or Chrome on IOS.
Does anyone know of an easy way (easy for the end user) to make this work?
Over at Reddit, a MATLAB user asked about when to use a script vs. a live script. How would you answer this?
Hi
I am using simulink for the frequency response analysis of the three phase induction motor stator winding.
The problem is that i can't optimise the pramaeter values manually, for this i have to use genetic algrothem. But iam stucked how to use genetic algorithum to optimise my circuit paramter values like RLC. Any guidence will be highly appreciated.
It is not possible to link ThingTweet with Twitter. When I authorize through "Authorize ThingTweet to access your account?", it says "Redirecting you back to the application. This may take a few moments" and logout in thingtweet. Its looping. How to fix this issue?
It didn't work even after deleting cookies or trying with MS edge browser as detailed here

Sending temperature and humidity values to a thingSpeak channel using a NodeMCU(esp8266) and the ThingSpeak library. The problem is that the graphs do not update dynamically even if values are sent and received regularly. To update the graphs I have to refresh the page every time. The numeric displays and other widgets update regularly. How can I solve the problem?

I am a beginner of deep learning, and meet with some problems in learning the MATLAB example "Denoise Signals with Adversarial Learning Denoiser Model", hope very much to get help!
1. visualizaition of the features
It is my understanding that the encoded representation of the autoencoder is the features of the original signal. However in this example, the output dimension of the encoder is 64xSignalLength. Does it mean that every sample point of the signal has 64 features?
2. usage of the residual blocks
The encoder-decoder model uses residual blocks (which contribute to reconstructing the denoised signal from the latent space, ). However, only the encoder output is connected to the discriminator. Doesn't it cause the prolem that most features will be learned by the residual blocks, and only a few features that could confuse the discriminator will be learned by the encoder and sent to the discriminator?
