In short, AI/ML systems learn from structured and unstructured data gathered from various sources to mimic human actions and make decisions and predictions. Thus, it’s essential to ensure that the data collected is of the highest quality and complies with industry regulations.

As simple as it may seem, data collection is easier said than done, as the quality of data directly impacts the AI/ML model’s outcomes. Stakeholders must know the starting point of their data collection journey, which is, knowing what type of data to collect!

Types of Data Collected for AI/ML

Data collection for AI/ML is a broader term wherein data can be anything, including text, images, videos, audio, or a mix of all these. In other words, anything that helps a machine perform actions and make decisions is data in this space.

Broadly speaking, datasets can be derived from structured and unstructured sources. Structured datasets have an explicit meaning and format and are easily comprehensible for machines. On the other hand, unstructured datasets don’t have any fixed structure or format. The human-in-the-loop approach is required to extract valuable insights from unstructured datasets.

Below are the different types of data used for training machine learning algorithms. Take a look:

I. Text Data

Text data is one of the prominent forms of data. Structured sources include online forms, databases, spreadsheets, medical devices, GPS navigation units, and more. Contrarily, unstructured text data includes handwritten documents, email responses, surveys, images of text, social media comments, etc. Applications such as chatbots, translation tools, and sentiment analysis rely heavily on textual datasets.

II. Image Data

Image data plays a pivotal role in computer vision tasks such as object detection, facial recognition, landmark identification, and medical imaging analysis. This type of data is collected from cameras, satellites, drones, digital archives, etc. High-resolution images with proper annotations ensure that machines interpret visual information accurately.

III. Audio Data

Audio data includes human speech, environmental sounds, audiovisual content, phone call recordings, musical compositions, and more. Training audio models often requires transcription and phonetic annotation to convert sounds to text and understand accents and pronunciation to address queries in multiple languages. Using this, businesses can develop more intelligent chatbots, and virtual assistants.

IV. Video Data

Video data extends the capabilities of AI/ML systems by integrating visual and audio information. This type of data can be sourced from computer vision, digital imaging, and more. In fact, video data annotation is the driving force behind autonomous vehicles and other CV-enabled technologies such as security surveillance and facial recognition.

By combining these data types, organizations create multi-modal datasets that enhance model capabilities, leading to comprehensive solutions that drive agility and efficiency within business processes. Thus, the next important question is how to collect data for AI.

Top Data Collection Methods for AI and ML

There are multiple ways to gather data, and knowing the right method is essential to make the entire process fruitful. While some companies resort to professional data collection services as a cost-effective way to get high-quality data, others gather data independently using various tools and methods. Some of the key techniques include:

1) Crowdsourcing

Crowdsourcing involves engaging a large group of individuals to contribute data through a shared platform. This method offers a wide variety of data since the data is gathered from across the globe. Moreover, crowdsourcing effectively gathers both primary and secondary data, ranging from academic research data to user-generated content. Businesses can easily eliminate the cost associated with hiring data collection professionals and equipment. The only drawback of this method is that data quality becomes difficult to track since many contributors work remotely.

2) In-House Data Collection

Organizations may establish in-house teams to gather proprietary datasets tailored to their unique needs. While resource-intensive, this method ensures greater control over data quality, integrity, and alignment with project objectives. This method is most effective when the dataset requirement is small or the data is highly sensitive. And, if the problem statement is precisely defined, in-house data collection works the best.

3) Off-the-Shelf Datasets

Pre-existing datasets, available from public or commercial sources, provide a cost-effective solution for data collection. This is ideal for projects when the requirements aren’t too specific and require a wide range of data. An image recognition system, for instance, can be fed with off-the-shelf datasets. Majorly, prepackaged datasets meet 70-80% of the project requirements; however, the remaining 20-30% data gap can be challenging. Though this option may be affordable initially, the data gaps prove costlier in the long run as resources are required to fill these.

4) Automated Data Collection

Web data collection through automated tools like web crawlers and APIs enables organizations to retrieve large volumes of publicly available data. Automated data collection is synonymous with agility, efficiency, and scalability, as these tools combine AI, ML, and RPA with human expertise. It is the most efficient tool for primary and secondary data collection, which also eliminates the chances of human errors. What sets this approach apart is its ability to gather real-time data. At the same time, maintaining automated tools proves costly, especially for companies with a budget crunch, and requires compliance with legal and ethical standards.

5) Generative AI

The hottest topic of every boardroom meeting, Generative AI models, such as GPT, can synthesize new data based on existing patterns. This method is particularly useful for creating synthetic datasets in scenarios with scarce or sensitive real-world data. The data generated through this method can be in the form of text, images, videos, audio, etc. Besides synthesizing data, Generative AI helps with data augmentation and simulation of missing scenarios.

The only loophole of this approach is that the generated data might not accurately represent real-world scenarios. Simply put, the ML model might perform well with synthetic data but fails to respond aptly when presented with real-world challenges.

6) Reinforcement Learning from Human Feedback (RLHF)

RLHF integrates human expertise into the training loop by refining model predictions based on user feedback. This iterative process enhances the quality and relevance of training datasets, ensuring models align with real-world expectations. On the flip side, relying on human feedback is not only time-consuming but also makes it difficult to scale in the case of large applications. Moreover, human biases might be introduced to the AI/ML algorithms, leading to wrong decisions. In worst-case scenarios, this might widen the societal gap.

As evident, each method contributes to building a robust data pipeline, accelerating the development of AI/ML solutions. However, the data collection process is riddled with challenges such as cleaning and processing, privacy and ethical considerations, biases, and more.

Common Challenges in Data Collection
