Moved Windows folders still appear in the Users folder
I just moved a few folders from my C:UsersSteve folder to a folder on my D: drive. I did this using the Location tab on the properties of each folder. The folders moved without issues. I expect to see that the moved folders will appear at their new location and be gone from the old location.
The folders that I moved were Pictures, Music, Videos, Downloads, Documents and 3D Objects.
If I select my Personal Folder from the icon at the bottom of the Start menu, I see what I expect. If I use Explorer to go to C:UsersSteve I also see what I expect.
If I select “Steve” from the quick links menu on the left side of Explorer, the folders that I moved are still there. The Location tab on each of the icons properties does show the location on D:, but I don’t expect to see all these files/folders from multiple locations gathered together.
Why is this happening? Is it normal? How do I distinguish “C:UsersSteve” from “Steve Norton” in the Explorer? Where does “Steve Norton” exist on the computer?

Deploying GPT-4o AI Chat app on Azure via Azure AI Services – a step-by-step guide
Deploying GPT-4o AI Chat web app on Azure via Azure AI services – a step-by-step guide.
Hello everyone, welcome to my latest blog post!
My name is Suzaril Shah and I am a Gold Microsoft Learn Student Ambassador and a Microsoft Certified Trainer from Malaysia.
I am excited to share the guide to deploy a GPT-4o AI Chat Web App on Azure via Azure AI Services.
Introduction to Azure AI services
Azure AI Services is an advanced suite of tools and services on Microsoft Azure designed to help businesses create, deploy, and scale AI solutions. It includes a variety of pre-trained models for tasks such as natural language processing, computer vision, and decision-making. These models, such as GPT-4 for text generation and DALL-E for image generation, offer state-of-the-art capabilities that can be customized and fine-tuned to meet specific business needs. Azure AI Services is built on Microsoft’s reliable and scalable cloud infrastructure, ensuring high performance, security, and seamless integration with existing workflows and applications.
To follow the guide for deploying a GPT-4o AI Chat app on Azure, you need the following requirements:
Requirements:
Microsoft Azure Account and Subscription. If you don’t already have one, you can sign up for an Azure free account. For Students, you can use the free Azure for Students offer which doesn’t require a credit card only your school email.
Filled up the Azure OpenAI registration form
Domain name (optional)
Step 1: Getting Access to the Azure AI Service.
To get access to Azure OpenAI services, you will need to fill up the registration form indicating the use for the Azure OpenAI platform. Once your access to Azure OpenAI is approved you will receive an email similar to the screenshot below:
You can now access the Azure AI Service from Azure portal. Simply search and click the “Azure AI Service” keyword on the Azure portal search bar.
Step 2: Create Azure AI Services on Azure
You can create the Azure AI Services by clicking on the “+ Create” button on the Azure AI Services overview page. Fill up the details required to create the Azure AI Services > Click on “Review + create” > “Create” button to deploy the Azure AI Services on Azure.
When the deployment is completed, click on “Go to resource” > “Go to Azure AI Studio” > Sign in to your Azure account to access the Azure AI Studio.
Deploying models on Azure AI Service
To create a chat playground (or use any of the Azure AI services), one must create at least one model deployments on Azure AI Studio. Since we are deploying an AI Chat App, we can use the GPT (Generative Pre-training Transformer) models available on Azure AI Studio.
Using deep learning algorithms, these models—which include GPT-3, GPT-3.5, GPT-4 and their latest iteration, GPT-4o – process and produce text that sounds human. Their ability to forecast and produce consecutive text depending on previous input, therefore mimicking a conversational partner like a human, has earned them a nickname: “chat completions“.
The term “chat completions” emphasises how useful the models are for finishing textual exchanges, modelling conversational dynamics, and producing answers that are quite similar to human output. Development of AI-driven chatbots, content creation tools, and programming helpers depends critically on this feature. Azure AI services enable developers and businesses to build advanced, AI-enhanced applications that push the limits of natural language processing and human-computer interaction by using the predictive potential of these models.
There are a lot more AI models in Azure AI studio, which includes:
Dall-E models – Generative AI used to generate Images/Pictures from user text input.
GPT/completion models – Generative AI used for chat completions, predicts and generates text to continue a given prompt, learning from vast datasets to produce relevant and coherent content
Embeddings models – Generative AI used to generate numerical representations (embeddings) of text, capturing its semantic meaning in a way that allows for the comparison and analysis of text data.
The list of models are accessible when you click the Model Catalog sub-tab on the left of the navigation menu on Azure AI studio:
Step 3: Creating Model deployment on Azure AI Services
Click on the “Deployments” sub-tab under the “Shared resources” tab on the navigation menu on the Azure AI Studio > “Create Deployment” and select a GPT model from the model catalogue.
GPT-4 on Azure is the latest advancement in natural language processing from OpenAI, offering significant improvements in accuracy, coherence, and versatility over previous models. This model can handle a wide range of tasks, from generating human-like text and understanding complex queries to summarizing documents and creating creative content.
GPT-4o supports multimodal capabilities, enabling it to handle both text and image inputs. This latest model, currently available in preview, allows users to integrate natural language processing with visual data, creating a richer and more interactive AI experience. This functionality opens up a wide array of use cases, such as analyzing images, generating descriptive text, and even integrating audio capabilities in the future.
Select GPT-4o models and click on the “Confirm” button and fill up the deployment details for the GPT-4o models > “Deploy” to finalize the deployment details.
Note: Selecting the Global Standard deployment type will allow you to leverage Azure’s global infrastructure to dynamically route traffic to the data center with best availability for each request. Global standard will provide the highest default quota for new models and eliminates the need to load balance across multiple resources.
Chat Playground on Azure AI Services.
Users can test and discover the possibilities of sophisticated language models such as GPT-4 through the Chat Playground on Azure AI Services. Developers, researchers, and business users can better grasp how these AI models can be used for a variety of tasks, including automated answers, content production, and customer care, with the aid of this intuitive interface.
With the Chat Playground, users may interact with the model directly by entering text questions and receiving real-time responses. It is simple to evaluate and adjust the model’s behaviour in accordance with particular needs thanks to this interactive arrangement. To access Chat Playground on Azure AI services, select the “Chat” sub-tab under the “Playgrounds” tab on the navigation menu on the left > Select the Model Deployed earlier.
The Chat Playground settings can significantly influence the behavior and performance of your Chat App. Here’s an overview of the key settings you can configure:
System Message: Start by defining your model’s purpose with the system message. This message shapes the model’s behavior and core functionality. To ensure specificity, include source data and examples of ideal responses. This helps the model understand its role and generate more accurate and contextually appropriate outputs.
Add Your Data (Preview): Enhance your model’s understanding and responsiveness by uploading or connecting your own data. Providing additional context and relevant information enables the model to generate more precise and informative responses. This feature is currently in preview, and you can learn more about how to connect your data.
Parameters: Fine-tune your model’s behavior with various parameters. Adjust the temperature to influence the creativity of the responses—the higher the temperature, the more creative and diverse the outputs. You can also set the maximum number of response tokens to control the length of the responses, ensuring they are concise and relevant.
Step 4: Deploy the Chat Playground on Azure via App Service Plan.
To deploy the AI Chat playground, click on the “Deploy to a web app” button on the top of the chat playground section and fill up the deployment details > “Deploy” to finalize the deployment.
Note: Enabling the chat history option will add additional charge (on top of the Azure App service plan) to your Azure subscription since all historical chats will be stored in the Cosmos DB database.
To view the deployment status for the web app, click on the “Deployments” sub-tab on the left-side of the Navigation menu on Azure AI services > “App Deployments” tab.
You can access the AI Chat web app by clicking on the deployment name once the Deployment status shows “Succeeded”. Sign in to your Azure account, click on the “Consent on behalf of your organisation” checkbox > “Accept”.
You should now be able to access the Chat Playground web app.
Step 5: Assign the AI Chat web app to a custom domain. (Optional)
You can also assign a custom domain for the AI chat web app to make it more accessible, and easy to remember to your end users, as compared to using endpoints like: https://gpt4-shah.azurewebsites.net/ . Go back to the Deployment page on Azure AI Studio and Click on “Azure Portal” under the “Manage” category.
Under the Properties tab, you should be able to see the “Domains” category. Click on the “Add custom domain” hyperlink to assign a domain to the web app > “Add custom domain”
Under the “Add custom domain” configuration page, make sure to select the “All other domain services”, if you have purchased domains from external TLD registrars. Enter your domain/sub-domain into the “Domain” field. In this case, I am going to assign the “gpt4.suzarilshah.uk” domain and verify the domain using the CNAME record type.
Add the DNS records on your DNS host so Azure can verify that you own the domain and can start pointing the web app’s traffic to the domain/subdomain.
After the DNS records are successfully added on the DNS Host, click on the “Validate”> “Add” button on Azure. Validation can take up to 72 hours to allow the DNS records to be completely propagated across the internet.
Step 6: Configure the AI Chat Web App Redirect URL (only required if you configure custom domain)
To enable authentication using Microsoft Entra ID (formerly Azure Active Directory) for a web app with a custom domain in Azure, you need to configure the Redirect URI (or URL) in the Microsoft Entra ID settings to match the custom domain of your web app. This ensures that the authentication process redirects users back to the correct URL after they sign in.
Navigate to the Microsoft Entra ID on the Azure Portal > Enterprise Applications > [YOUR_APP_NAME] > Under the “Manage” tab, click on the “Authentication” sub-tab on the left side of Azure Portal navigation menu. Click on the “Add URI” hyperlink and add a new Redirect URL using the following format:
https://[custom subdomain/domain]/.auth/login/aad/callback
Review the configuration and click on “Save” to save the configurations. Now you should be able to authenticate and access the web app from the custom domain you have configured just now.

fprintf(‘accuracy=%f’,sum(diag(confMat))/sum(confMat(:))); Hello. Thanks for reading my question. Sorry if it’s an easy question but I’m new in Matlab and Computer Vision. I’m trying to extract features from training images. I need to use histogram of color, histogram of gradient, SIFT-like features and compare their performance. I’m lost and have spent days to find a good way to use. How would you extract features in this example? I have put %Start and %End where I need to do that.
A written code would be greatly appreciated.
% Step-1: Load training and test data using imageSet.
imageDir = fullfile(‘./data’);
% imageSet recursively scans the directory tree containing the images.
flowerImageSet = imageSet(imageDir, ‘recursive’);
%% step-2: Partition the data set into a training set and a test set.
tmparr=randperm(80);
arrTrainID=tmparr(1:50); %training ID;
arrTestID=tmparr(51:end);% testing ID;

Data format for batch inferencing of finetuned phi-3 model
I created a batch endpoint and deployed the model there. I created a job and provided the data that I formatted in the manner shown in the second image. I simple passed the whole prompt as a string in a single column dataframe which I converted into csv before writing it in a .csv file.
The data format (.csv) that I am using for inferencing produces the error : “each data point should be a conversation array” when running the batch scoring job. All the documentations provided online deal with image data so I am unable to figure out the format for my data. I am trying to create a job from the “Create job” button under the batch endpoint. I am using Azure ML platform and I have fine-tuned a phi-3-mini-4k-instruct model using the “eurlex” data available on huggingface. The training process required a jsonl format for the training data. However, while trying the run the batch inference, the data assets are only stored in csv,png etc. formats.The training data looked something like the first image. I converted this into jsonl format. I created a batch endpoint and deployed the model there. I created a job and provided the data that I formatted in the manner shown in the second image.

I have also tried making a dataframe with 3 columns – system,assistant,user but it doesn’t work either. Read More

Could someone please explain something to me?
I have quit Onedrive for some time now, as I don’t need a ‘Backup’ I do my own regular Image backup to an External HDD.
But I notice that when you expand the Onedrive file (see attached photo) you seem to see that you have a duplicate of everything you have in your computer’s ‘Documents’ and ‘Pictures folders’. Is Onedrive storing a complete second copy of Documents and Pictures etc. using up double the space on your computer’s hard drive?

Command vs. Powershell
I think I mucked up some a setting related to Command/Powershell. Now if I run Command from the Start icon, I get a Command window – but if I pin it to the task bar, the next time I open from there, I get Powershell! How do I fix it so I get a Command box when I open it from the task bar – I already have a Powershell icon there.

Shutdown/restart screen is missing
Hello, my OS stopped to show shutdown/restart screen phase text (Restarting…/Shutting down…), there’s just blank black screen.
Since the system restarts/shuts down it may be a cosmetic issue but also can indicate something deeper is broken, so I’d prefer to have it fixed.
There’s no error messages or unusual behaviour otherwise, I’m having 23H2 updated to Moment 5 recently. Can I get some ideas what gone wrong?

I am working on a simulation in Simscape involving a three-phase rectifier fed by a three-phase synchronous machine (alternator with round rotor).
I have successfully modeled both components, but I am facing a significant issue. When I replace the three-phase voltage source with the alternator, the input voltage to the three-phase rectifier becomes nearly zero, despite the alternator producing a stable three-phase voltage.
Here are the details of my setup:
Rectifier Configuration:
Using a Universal Bridge block in Simulink and a Converter (Three-Phase) block in Simscape.
Parameters for Universal Bridge:
Number of bridge arms: 3
Snubber resistance Rs: 1e5 Ohms
Snubber capacitance Cs: inf
Power electronic device: IGBT / Diodes
Ron: 1e-3 Ohms
Forward voltages [Device Vf(V), Diode Vfd(V)]: [0 0]
Parameters for Converter (Three-Phase):
Forward voltage, Vf: 0.00000001 V
On-state resistance: 0.001 Ohm
Off-state conductance: 1e-6 1/Ohm
Threshold voltage, Vth: 0.1 V
Integral protection diode: Diode with no dynamics
Forward voltage: 0.00000001 V
On resistance: 0.001 Ohm
Off conductance: 1e-5 1/Ohm
Snubber: RC snubber
Snubber capacitance: 1e-7 F
Snubber resistance: 1e5 Ohms
Alternator Parameters:
Three-phase synchronous machine with a round rotor.
Proper initialization and verified output: stable three-phase voltage and current.
Simulation Settings:
Solver: ode23t
Proper machine initialization.
Problem Description:
The output of the alternator is a good three-phase voltage and current when checked independently.
When the alternator is connected to the rectifier, the input voltage to the rectifier is distorted and significantly diminished.
No connection issues were found, and the simulation settings were adjusted, including changing the solver to ode23t, but the problem persists.
Questions:
What could be causing the input voltage to the rectifier to be nearly zero when using the three-phase synchronous machine as the source?
Are there specific snubber values or configurations that could resolve this issue?
Could there be any interaction or parameter mismatch between the alternator and the rectifier that I need to address?
What are the best practices for setting snubber parameters in such a setup?

Different number of classes in training and testing data
Hello Everyone!
I am trying to develop a classifier for classification of different human activities i.e., standing, walking, sitting, laying in bed etc.
I have total of 6 classes in my dataset (concatenated all activities) and training multiple classifiers and also implementing K-fold cross validation during training.
I split my data into train and test set, train my classifier and then test my classifier and accuracies are pretty good (almost 95%). (I wont go into details of segmentation, feature extraction etc.)
The problem that I am facing right now is testing my classifier with completely new data. The following are some notable things about the new test data:
1) The new test data has 5 classes instead of 6.
2) The new test has continuous activities e.g., a person performing all 5 activities in quick succession without any break. Whereas, during training data, each activity was seprately recorded and then I concatenated all activities.
3) The accuracy that I am getting is around 70% (pretty bad) and also most of the misclassifications are being thrown into the class that is not in the new testing set e.g., class 6 is not present in new test set but when I check predictions, the classifier is saying (for major portion of activities) that it belongs to class 6.
I cannot reduce the number of classes in my training set because when I implement this in real-time, the subjects will perform all the 6 activities but ofcourse not all together and one by one e.g., in real-time, the subject will perform activity 1 (the classifier will classify it as 1) then activity 2 (the classifier will classify it as 2) and so on.
Can you people help me understand, which parameters I should observe to improve the accuracy of my classifier for the new test data? Because 70% is not acceptable to me. And any suggestions on the mistakes that you have seen here and can correct me and tell me the right path.
Thank you so much :)Hello Everyone!
I am trying to develop a classifier for classification of different human activities i.e., standing, walking, sitting, laying in bed etc.
I have total of 6 classes in my dataset (concatenated all activities) and training multiple classifiers and also implementing K-fold cross validation during training.
I split my data into train and test set, train my classifier and then test my classifier and accuracies are pretty good (almost 95%). (I wont go into details of segmentation, feature extraction etc.)
The problem that I am facing right now is testing my classifier with completely new data. The following are some notable things about the new test data:
1) The new test data has 5 classes instead of 6.
2) The new test has continuous activities e.g., a person performing all 5 activities in quick succession without any break. Whereas, during training data, each activity was seprately recorded and then I concatenated all activities.
3) The accuracy that I am getting is around 70% (pretty bad) and also most of the misclassifications are being thrown into the class that is not in the new testing set e.g., class 6 is not present in new test set but when I check predictions, the classifier is saying (for major portion of activities) that it belongs to class 6.
