Hi, folks. Welcome to our talk today on incorporating machine learning to your node.js applications. We're living in an era where machine learning is transforming the way we interact with technology. So sit back, relax, and get ready to learn how you can take your node.js application to the next level with machine learning. But first, let me introduce myself. My name is Mariam Bila, and I'm excited to be here with you today. I'm a senior full stack pro designer at Nodetors, and I am passionate about combining technology with community development.

I'm honored to be sharing my knowledge and insights on incorporating machine learning into node.js applications with you. I hope that through our discussion today, you gain valuable insights into how machine learning can be integrated into node.js applications to create more efficient and effective solutions. So without further ado, let's get started. I'm from Colombia, South America. As Colombians, we are proud of the diversity that exists in our country, including the many different shades of skin that can be found across our communities. From the Caribbean coast, the Andean mountains, we have a range of skin tones that reflect our unique histories and cultures. Yes, I am Colombian and Latina. And with this clear, let's jump to the main theme of our presentation.

As more and more applications become reliant on data-driven decision-making, machine learning is quickly becoming a critical tool for developers to incorporate into their applications. node.js, with the speed, scalability, and ease of use, has become a popular choice for building these type of applications. However, incorporating machine learning into node.js applications comes with its own set of challenges and best practices.

So as Colombians and also Venezuelans, there is one thing that we all know and love, and that's Arepas. In fact, according to the Colombian Academy of Gastronomy, these are 75 different varieties. So personally, I'm firmly believe that nothing can leave you in a mood like a warm, gooey Colombian cheese arepa. That's why I'm excited to share with you some tips and best practices to help you make the perfect machine learning integration every time. And with these tips, your node.js applications will be an absolute delight. We will say un encanto. So wherever you are, seasoned, a pro, or a beginner, join me as we explore the secrets to making the perfect arepa.

Let's get started. So implementing machine learning can be a daunting task, especially if you are not familiar with the technology. But don't worry, we're here to help. So let's dive in. The first step will be discussing it so carefully, considering the problem you want to solve with machine learning. Before diving into implementing machine learning algorithms in your node.js application, it is essential to have a clear understanding of the problem you want to solve and the approach you take to train and test your machine learning model. By taking the time to carefully consider the problem, you'll be able to identify the appropriate machine learning algorithms and techniques to use. Many machine learning frameworks are available, each with its own strengths and weaknesses. And when choosing a machine learning framework for your node.js, you need to consider all the factors such as ease of use, community support, and the specific needs of your application. Some popular machine learning frameworks for node.js include tensorflow.js, FrankJS, and ML5.js.

I want to explain this with a simple code example. So this is writing javascript and use the tensorflow.js library to create and train a simple sequential model with one dense layer. The model is then used to predict a new input value. So with this library, I create, compile, and train a simple neural network that's the problem I want to solve that can predict the outputs for a linear function. So the first thing is the problem you want to solve. The second tip will be start with a simple machine learning model. So starting with a simple model is important when incorporating machine learning into your node.js application. This will help you better understand how machine learning works and how to integrate it into your application. As a basic model works, you can gradually add complexity and redefine your machine learning algorithm. Let's jump again to a code example. So this code is writing javascript and use the FrankJS library to create a simple neural network with one hidden layer. So the network is then trained on a small input and output values data set and use the predict a new input value. Moving to our third tip, which is to use the right data. As we already discussed, the success of your machine learning model depends heavily on the quality of the data you use to train it. So it's important to ensure that the data you are using is representative of the problem you are trying to solve.

And this is of high quality. So to ensure that your data is a high quality, it's often necessary to clean and preprocess it before feeding into your model. This involves removal, duplicate, dealing with missing values, and transforming the data into a format that is suitable for your model. So clean, transform, and preprocess your data before feeding into your model. That's a good advice.

The tip number four would be monitor and evaluate your machine learning models. So machine learning models can be difficult to debug. So monitoring and evaluating model as it runs is important. Use accuracy, precision, and recall metrics to measure your model performance. Keep an eye out for any issues or errors during training or deployment. One of the best ways to evaluate your model is using accuracy, precision, and recall metrics. These metrics can help you understand how well your model is performing and whether or not it's meeting your expectations.

The tip number five is think about scalability. So as you know, machine learning models can be computationally intensive. So it's crucial to consider scalability when incorporating machine learning into your node.js application. One option is to use cloud-based services such as aws, GCP, or azure to help your machine learning models. These services can provide the computational power needed to run your machine learning models without putting a strain on your application resource. Another important aspect of scalability is making sure your application can handle the increases in load that machine learning processing may require. You may need to optimize your application code or infrastructure to ensure that it can handle the increased computational demands.

The tip number six will be use transfer learning. So transfer learning allows you to reuse pre-trained machine learning models for new tasks. This can save time and computational resource compared to training a new model from scratch. Use transfer learning in your node.js application to speed up your machine learning development process.

Finally, I know it's supposed to be the end and we don't talk about Bruno, but testing and monitoring your machine learning model is critical to ensure data performance, accuracy, and reliability. So consider using our product Ensolid console to monitor your node.js application to ensure the quality of your machine learning models.

Now, you are ready to fly on a donkey unicorn. Just kidding. So let's summarize the tips. So the first tip, choose the right machine learning framework.

The second will be a start with a simple machine learning model. The third, use the right data. The fourth is monitor and evaluate your machine learning model. The fifth, think about scalability. The sixth will be use transfer learning. And the tip number seven is test and monitor your machine learning models. Surely, you'll learn something to do your own app repos. And that's all. Thank you.
