How can you demonstrate different types of models with your computer vision portfolio?

Based on the particular needs of the application, I strategically selected the best platform for implementing my strategy. Choosing a web application made it possible to utilize it on several devices, which increased the number of users. Among the things to take into account were ways to control latency and guarantee a responsive user experience. In order to maximize the model's performance and balance computational demands with the application's overall functionality, resource efficiency had to be prioritized. Extensive testing was conducted during the deployment phase to identify possible bottlenecks and guarantee the model's seamless integration into the selected platform.

To demonstrate different types of models in your computer vision portfolio, start by choosing a problem like facial expression recognition or object detection. Then, find or create a diverse dataset relevant to your problem, ensuring it reflects various scenarios. Select different models such as Convolutional Neural Networks (CNNs) for image classification or Recurrent Neural Networks (RNNs) for sequence prediction. Train and evaluate each model, showcasing their effectiveness through metrics like accuracy and precision. Deploy your models using platforms like web or mobile apps, providing a user interface for interaction. Finally, showcase your portfolio on platforms like GitHub or LinkedIn, emphasizing your skills and project outcomes.

Begin by identifying a specific problem that your computer vision project will address. This could range from object detection to facial recognition or even complex scenarios like autonomous vehicle navigation. Clearly articulate why this problem is significant and how solving it can make a difference. This sets the stage for your project, providing context and showcasing your ability to tackle relevant issues in the field.

For me its like this 1. Thinking about the problem you have until you understand what exactly it is that you are solving. 2. Define the building blocks for solving the problem 3. Research well about the problem you are trying to solve. The research could possibly includes understanding about problem, nuances about the problem, nuances during solution etc. 4. Always think about how we are going to benefit the society in return.

Include a variety of projects in your computer vision portfolio to showcase your versatility and expertise across different types of models. For instance, you could demonstrate traditional machine learning approaches like SVM or decision trees alongside deep learning models such as convolutional neural networks (CNNs) or recurrent neural networks (RNNs). By showcasing a range of projects, you demonstrate your ability to adapt to various problem domains and apply appropriate techniques to address them effectively.

When selecting or creating a dataset for your computer vision project, ensure it reflects the diversity of the real-world scenarios your model may encounter. Include variations in lighting conditions, backgrounds, perspectives, and object poses to enhance the robustness and generalization of your model. Additionally, strive to represent diverse demographics, cultures, and contexts within your dataset to avoid biases and promote inclusivity in your models.

Securing the right dataset is pivotal. If you're working on a unique problem, you might need to compile your dataset, which could involve web scraping or manual collection. Explain the process of gathering, preprocessing, and splitting your data, as this demonstrates your hands-on experience with real-world data. Highlight any challenges you faced during data preparation and how you overcame them.

Finding the right fuel to power your computer vision project is crucial. You can either leverage existing datasets readily available online on platforms like Kaggle, ImageNet, or COCO. Alternatively, if you seek a unique challenge or data specific to your problem, you can embark on the adventure of collecting your own data. Tools like web scraping, cameras, or even mobile applications can be employed for this purpose. Preprocessing, annotation (labeling), or data augmentation techniques may be necessary to ensure its quality and effectiveness for training. Finally, splitting your data into designated training, validation, and testing sets is essential.

the next step after selecting the problem or project is to gather data set or create you own via web scraping or by camera. For data collection you can get from kaggle, ImageNet, Coco, or roboflow. Once collected data do annotations and do data augmentation. Data augmentation is best way to generate more data of different variety from existing data. After that split data into training, validation and testing data set.

Once you've got your problem, you need data to work with. Look for datasets that are relevant to your chosen problem. Websites like Kaggle or Google Dataset Search can be treasure troves. If you can't find the perfect dataset, consider creating your own. This step is crucial because it provides the raw materials for your models.

When embarking on an AI, especially, CV project, selecting the right model is a strategic decision that hinges on the specific requirements of the problem. Leveraging pre-trained models from TensorFlow, PyTorch, or OpenCV can significantly expedite development, tapping into the wealth of learning from large, diverse datasets. However, when uniqueness is key, or data is highly specialized, crafting a custom model from scratch allows for bespoke architecture and parameter tuning. Whether you stand on the shoulders of giants with pre-trained models or chart a new path with a custom build, the key is to align the model's capabilities with your project's unique challenges and goals.

Discuss the rationale behind the choice of model for each project. Whether you’re utilizing pre-trained models and fine-tuning them for your specific task or building custom models from scratch, explaining your selection process showcases your understanding of various architectures and their suitability for different problems. Include details about any adjustments or optimizations made to tailor the model to your project’s needs.

When selecting or designing a model for your computer vision project, consider the complexity of the problem you're addressing. For simpler tasks like image classification, a basic convolutional neural network (CNN) may suffice, while more complex tasks such as object detection or image segmentation may require deeper architectures like Faster R-CNN or U-Net. Choose a model that strikes a balance between accuracy and computational efficiency based on your project's requirements and constraints.

Next, choose the right model type for your mission. Briefly explain why you picked this specific model and why it's a good fit for the problem and data you have.

To demonstrate that you can make an excellent selection of the model, I recommend looking at Kaggle to find a related competition and see which models perform better for this task. Then, you can go to the Model or Code sections and download a model that you might use as a baseline for your improvements. Do not forget to share the reference for the author.

Detail the training process, including the selection of loss functions, optimizers, and other hyperparameters. Discuss how you monitored and addressed issues like overfitting or underfitting. Highlight the evaluation metrics used to assess your model's performance, such as accuracy, precision, recall, and F1-score. This shows your commitment to rigorously validating your model's effectiveness.

Then, it's training time! Briefly touch on the training process and how you evaluated your model's performance. Did it ace the test?

After data collection, preprocessing and selecting the model the next step comes that is to train the model on existing data set. After training the model evaluate it on the testing data set and check its accuracy. You also use a confusion matrix to evaluate your model. And by seeing at results you can check the performance of model is it trained well or has underfitting or overfitting issue. Also use validation data set for hyperparameter tuning.

Training your model is where the magic happens. Use your dataset to teach the model how to solve the problem. Once trained, evaluate its performance using metrics like accuracy, precision, or recall. This process is akin to refining your art pieces, ensuring each one is ready for display.

Showcase how you deployed your model into a real-world application or service. This could be a web app, mobile app, or any other platform that allows users to interact with your model. Providing a user-friendly interface for non-experts to engage with your project demonstrates your ability to deliver practical, user-centric solutions. Share insights into the deployment process, challenges faced, and how you ensured the model's robustness and reliability in a live environment.

Breathe life into your creation! If you deployed your model in a real-world setting, like a web app or mobile application, briefly explain the chosen platform and the considerations involved (e.g., latency, resource efficiency). This showcases your ability to translate the model from theory to practice.

Deploy your models in a way that people can interact with, whether it’s through a web application or a live demo. Tools like GitHub Pages or Heroku can be useful here. Think of this as opening day at the gallery, where visitors come to see your work in action.

After training and evaluating model the next step is to deploy the model. There are various platforms avaiable for that like google cloud, aws, azure, heroku etc. You choose any platform depending upon the scalability, security, cost etc. After deploying the model you have demonstarte your model either using website, mobile app or desktop app. Also keep monitoring your model and check its performance.
