Building Your First AI-Based Application
AI no more remained the talk of the future but part and parcel of any modern application. Starting from power recommendation systems to automation customer service, the scope of AI is humongous. Of course, wanting to be a part of AI development, the following article is a guided way to building your first AI-based application.
1. Getting Basics Understandable over AI.
Worth knowing, before you dive in, is what AI actually means. At a basic level, it refers to systems or applications that can mimic human intelligence. Some of the kinds of technologies considered AI at their core are those which can:
Learn through data. That’s called Machine Learning.
The ability to comprehend or generate natural language; this is referred to as Natural Language Processing, or NLP.
This encompasses the ability to identify images or patterns. It is sometimes referred to as Computer Vision. The ability to make a prediction or choice. Such technology is inextricably linked with data- and indeed, this is what it is popularly referred to as: Predictive Analytics.
With this in mind, you’ll now be better positioned to decide which AI could best fit your needs.
Problem You Want to Solve Begin with a well-delineated problem. For each user case you might ask yourself, for instance:
What problem or opportunity do I want to solve?
Is it something that can be improved or automated with data?
Example:-
Product recommendations in a retail app based on the interests of its users.
Disease diagnosis from medical images on a healthcare app.
Obviously defined problems will make it easy for you to know which tools and techniques that can be used and how you can use AI to proceed with your work.
2. Prepare Your Data
Data is the life-blood of any AI system. Here is how you should go about handling it:
Data Acquisition: All the data which is going to be relevant for your problem should be gathered. For example, if it’s a chatbot, then it would require conversational data, whereas a recommendation system would need data regarding user behaviours.
Data Preprocessing: This step is all about cleaning and normalisation of data; that is going to make the data consistent. They must remove duplicate entries. They should also manage missing entries as well as correct formats as needed.
Data Labelling: We need to label out our data for every one of these models we are building here; that’s what the model gets right answers to when it trains .
Example:
In the above image recognition app, an image will be labelled as “cat”, “dog”, etc
Thanks to these tools and framework, building AI applications has never been easier. Here are some of the popular ones.
Programming Languages :
- Python: Primarily for AI, because it is easy to use as well as has a greatly long list of libraries.
- R: Almost all statistical analysis and machine learning is done through this.
Frameworks and Libraries:
- TensorFlow: It is a library by Google, and open-source based. It is oriented towards deep learning.
- PyTorch: Most known for flexibility, because it’s mainly used in research and production.
- Scikit-learn: The most accessible library, purely because the most basic machine learning algorithms are all implemented here
Keras: High-level neural networks API which runs on top of TensorFlow.
AI Platforms:
Google Cloud AI: You also have pre-trained models and tools for training customised models.
AWS AI Services: It provides APIs for computer vision, NLP, and so much more.
Microsoft Azure AI: It provides an extensive set of AI services.
3. Train Your Model
Now that you have made a model it is time for bringing it into action
Algorithm Selection: Depending upon the kind of problem that you’d be trying to solve, you select an apt algorithm for the problem. For example,
Linear Regression in case of continuous predictions
Use Decision Trees or Random Forest in case it’s a classification problem
Use CNNs if it is an image-based classification
Apply RNNs in the case of sequence data like time series or text
Training the model: Gather all the labelled data, input data, and iterate parameters to minimise as much as possible the errors in predictiveness
Test the model: Lastly, test how your model performs according to metrics such as accuracy, precision, recall, or F1-score.
4. Embedding the AI Model in Your Application
Now you’ve built your model. Finally, you’ll integrate it into your application. The question is-how?
Back-end Implementation: Create APIs that your application calls over for AI functionality using Flask or Django.
Front-end Implementation: Fetch and then render the insight-driven AI to the end-users using React or Angular.
For instance, a very good example would be when one is developing a frontend for a chatbot application; this is where the input from the user reaches the backend whereby the backend follows through with an AI model and finally renders out a response.
5. Deploying and Monitoring Your Application
Well, after developing an AI application, deployment simply means that the application is made available to the end-users. Let’s consider the following
Cloud Deployment: In AWS, Google Cloud, and Azure. It’s in those clouds that you will find ease of deployment of AI models
Containerization: Containers such as Docker ensure that the running environment is consistent for your app. Track the performances after deployment
Real-Time Monitoring: Understand what is going on on your app with either Prometheus or New Relic
Model Drift: You’ll have to change your model periodically as new data is introduced which would change the performance.
6. Iterate and Improve
AI applications shouldn’t exist in isolation; they must be subjected to continuous development: they have to solicit user feedback, apply their models to new data sets, and improve their algorithms to try getting more accuracy and usability.
Conclusion
It’s exciting enough, create your very first application using AI-from solving problems, manipulation of data, then coding. So armed with what you have learned so far, you can now create applications going to take the power of AI to provide smarter and more efficient solutions: limitless if one has a keen mind and proper tools.
