Basics of AI Software Development

AI software development involves creating systems that simulate human intelligence. An AI system can perform tasks like learning, reasoning, and self-correction. It relies on algorithms, data, and computational power to work effectively.

The following are the key AI subfields:

  • Machine Learning (ML): defines algorithms that allow systems to learn from data.
  • Natural Language Processing (NLP): this enables machines to understand and generate human language.
  • Computer Vision: This can process and interpret visual data (images and videos).
  • Deep Learning: This uses neural networks to model complex patterns in data.

Each of these subfields plays a critical role in shaping AI software and applications.

AI Software Development Steps

Outlined below are the 7 steps that form an integral part of the AI Development lifecycle.

Step 1: Purpose and Goals

The starting point in the life cycle is to identify the problem, that should solved using AI. The goal would need to be defined and the targets should be measurable. We would need to investigate and understand the current challenges in the existing system or the new system. The objectives could be defined as:

  1. Who is the target audience?
  2. What specific problem does it address?
  3. How will it benefit users?

A simple example could be enhancing a customer service chatbot. The chatbot would resolve customer queries in real time. It would require little or no human intervention.

Step 2: Gather and Prepare Data

Data is the foundation for any AI software. The right data sources need to be identified which could help procure high quality data. This would reduce the need to improve the AI model due to data limitations. Some of the steps could be:

  1. Data Collection: High quality data sources such as internal databases, public datasets, or user-generated data need to identified.
  2. Data Profiling: The data needs to be profiled. This means analyzing the structure of the data. It also involves examining the quality and characteristics of the data.
  3. Data Cleaning: The profiled data would then need to be cleaned i.e. remove errors, duplicates, outliers, and null values. Format conversion (if any) would need to be completed in this step. Once cleaned the data would need to be stored in a repository.
  4. Data Normalization: The cleaned data would either need to be normalized or de-normalized depending upon the requirement. Feature engineering for ML can be performed at this step.
  5. Data Enrichment: Any additional data sources (external / internal) can be added to the enrich the data set(s). Care should be taken to maintain that the data quality.
  6. Data Validation: The dataset needs to be verified for accuracy. It should also be checked for consistency. Custom validation rules are used for this process. These rules ensure conformity to the defined schema.
  7. Data Integration: The data obtained from multiple sources could be merged into a unified view to help resolve conflicts in data (e.g., duplicates, mismatched fields).
  8. Data Standardization: The unified data could then be standardized into a consistent format by using the business rules.
  9. Data Export and Storage: The final data set could either exported to a suitable format and then stored in a warehouse or mart or in the file system.
