Human-in-the-Loop AI

Better AI needs the right human judgment.

AI processes enormous volumes of data, makes predictions at speed and automates increasingly complex tasks. But real world data is rarely perfect.

Adept operates the human layer inside your AI workflow: curation, annotation, validation, evaluation and exception handling, delivered from Nairobi.

Where human judgment adds value

Real world data is rarely perfect.

01

Images are unclear and objects partially hidden.

02

Labels are inconsistent and language is ambiguous.

03

Model outputs are uncertain, and new situations appear that training data never covered.

As AI becomes embedded in real world use, maintaining data quality, validating outputs and managing exceptions becomes increasingly important. Adept provides the human layer within AI workflows, preparing and curating data, creating structured training datasets, validating outputs and resolving the cases that require judgment.

The objective is to put human judgment where it creates the greatest impact.

The AI data lifecycle

From training data to continuous AI improvement

As models move from development through testing and into production, the human role changes.

The human layer enters at different points depending on the model, the data and the consequences of an incorrect result. Adept designs and operates that layer end to end.

01

Prepare

Clean, organise and curate data for training and evaluation.

02

Annotate

Create structured datasets across image, video, text, audio and other data types.

03

Validate

Review annotations, ground truth and model outputs against quality rules.

04

Resolve

Investigate low-confidence predictions, unusual cases and exceptions.

05

Improve

Capture corrections and feedback that strengthen datasets and future performance.

Data→ Model→ Output→ Human review→ Feedback→ Improved model
Data types we annotate

Trained teams working to your taxonomy, not a generic one.

Every programme starts with your labelling rules, edge-case definitions and acceptance criteria. Reviewers are trained and calibrated against them, and output is sampled continuously.

Experience built through real AI data operations

Adept's HITL capability is built on long term operational experience. Since 2019, Adept has supported KITRO, an AI enabled food waste technology company, through annotation, data curation and validation workflows. As the client's technology and requirements have evolved, so has the work.

The engagement has required teams to work with evolving datasets, apply defined quality standards and support validation activities as requirements changed.

01Work with evolving datasets
02Apply defined quality standards
03Identify unusual and ambiguous cases
04Support validation activities
05Adapt to changing model and data requirements

This experience provides the operational foundation for Adept's broader Human-in-the-Loop capability. We are building on that foundation through increased team capability in areas such as LiDAR and 3D annotation, Generative AI evaluation and broader model review workflows.

Why Kenya
Nairobi, Kenya

Why Kenya for AI data operations?

Kenya has developed a strong base of digital talent with experience supporting international AI and data operations.

For AI companies this means access to an English speaking workforce that can be trained for structured, quality-controlled workflows across data types and use cases.

Adept combines that talent environment with managed delivery from Nairobi and experience operating long running international AI data programmes, as a social enterprise providing dignified work to youth and women.

The result is not simply access to people. It is the ability to build a managed human layer around an AI workflow.
Designed around your workflow

There is no single HITL model.

The right operating structure depends on what the AI is doing, where uncertainty occurs and what happens when the model gets something wrong. A practical HITL operation starts by defining eight things.

01

What requires human review

02

What can remain automated

03

When human review is triggered

04

What counts as an acceptable result

05

How reviewers are trained and calibrated

06

How quality is measured

07

How exceptions are escalated

08

How reviewer decisions are captured

Adept provides the operating structure around that human layer through trained teams, defined workflows, quality controls, supervision and performance management. This allows AI and product teams to focus on the technology while maintaining visibility and control over the human dependent parts of the workflow.

Frequently asked

Questions about Human-in-the-Loop AI.

01What is Human-in-the-Loop AI?
HITL is an approach in which people participate at selected points within an AI or machine-learning workflow. Their role can include preparing and annotating data, reviewing outputs, handling exceptions, validating results or providing structured feedback for future improvement.
02Is HITL the same as data annotation?
No. Data annotation is one important part of HITL, particularly during model development. HITL extends across the AI lifecycle through data curation, quality control, model evaluation, exception handling and production output review.
03Does every AI output need human review?
No. Human review is most useful where a model has low confidence, encounters an unusual case, produces an output requiring contextual judgment, or where the consequence of an incorrect result warrants additional oversight.
04Can HITL support Generative AI?
Yes. Human reviewers can evaluate generated responses against defined criteria such as relevance, accuracy, factuality, instruction following and safety. They can also compare responses and create structured human-feedback datasets.
05What data types can Adept support?
Adept's established experience is strongest in image-based annotation, curation and validation. HITL workflows also extend across video, text, audio, 3D and sensor data, and we are developing further capability in LiDAR, 3D annotation and Generative AI evaluation.
06Can HITL be introduced after a model is deployed?
Yes. Production AI can use human review for low-confidence predictions, unusual cases, exception handling, quality monitoring and the creation of new ground truth and feedback for future improvement.
