Hallucinations and

Language Models:
A Cheat Sheet
.
LLM Hallucinations
Instances where a language model generates outputs that are
incorrect, nonsensical, or completely detached from the input it was
given.
Causes:
Lack of context, overfitting, data imbalance, complexity of language,
and limited training data
Mitigation Strategies
Retrieval-Augmented Generation RAG + Templated System
(RAG) — retrieve information from Prompts — adding a layer of

Bias in AI Models
The presence of skewed or prejudiced assumptions within the
model's data or algorithms. This can result in unfair or discriminatory
outcomes that reflect societal prejudices or stereotypes.
Sources:
Training data, labels or annotations, algorithmic bias, implicit
associations, human input and influence, and lack of diversity.
By understanding the sources of bias in AI models, we can take
proactive measures to mitigate bias and promote fairness in the
design and implementation of AI systems.
Detection Methods Ethical Сonsiderations:
training dataset analysis, fairness and equity,
bias detection tools, transparency,
human evaluation, inclusivity,
diverse test cases, accountability,
monitoring and feedback user well-being,
mechanisms to track the data privacy,
model’s performance. regulatory compliance.

For businesses using LLMs, it is
important to understand that the
hallucinations and biases in models can
affect the quality of responses and the
effectiveness of their use. I recommend
introducing strategies such as the RAG
architecture, pre-generation, and fine-
tuning to minimize the risks of
hallucinations and biases in working with
language models.

How we handle it at MOCG
At Master of Code Global, we employ approaches aimed
at addressing these issues.
For example, we implement the RAG architecture and
additional control layers in our solutions that assess the
quality of LLM outputs and detect hallucinations to
enhance the understanding of context and generate
accurate responses. This is done through our LOFT: LLM-
Orchestrator Open Source Framework.
Additionally, we regularly audit and evaluate the model's
responses to identify and eliminate instances of
hallucinations and biases, maintaining an ethical approach
in the use of AI technologies.
