Document AI Assistant Training for the Banking & Financial Services Sector

Banks need answers accountable to auditors: credit analysts and compliance officers search clause-by-clause through policies, relevant POJK regulations, and decade-old committee memos. RAG saves significant search time, but every answer must show its source and never mix customer data into public-model prompts. The vector index becomes a new shadow database that must obey bank data-classification policy.

Banking & Financial Services-specific questions
Can this RAG run on-premise or in the bank's private cloud?
Yes. The deployment module covers fully on-prem options (self-hosted vector DB such as Qdrant or pgvector + local embedding models such as multilingual BGE) and private-VPC options with Azure OpenAI / Bedrock endpoints. Selection depends on the bank's data residency assessment.
How do we align RAG with POJK 11/POJK.03/2022?
We map RAG components (ingestion, index, retrieval, generation, observability) to POJK 11 IT risk articles: governance, change management, information security, business continuity. Training output includes architecture diagrams + RACI attachable to internal audit (SKAI) working papers.
Can Neksus pass bank vendor onboarding (RAS, NDA, vendor KYC)?
Yes. Neksus is used to bank RAS, NDA signing, and providing vendor KYC documents (deed, NPWP, domicile certificate, team profile, lightweight BCP). PPN invoicing and Indonesian bank contract formats supported.

Quick Answer

Enterprise RAG training is an engineering program that builds end-to-end retrieval-augmented generation over corporate corpus: chunking, embeddings, vector DB (Pinecone/Weaviate/Qdrant/pgvector), LangChain/LlamaIndex orchestration, RAGAS & TruLens evaluation, plus OWASP LLM Top 10 2025, NIST AI RMF GenAI Profile, and UU PDP hardening.

Without structured evaluation, RAG is only 'feels right'

RAG demos look convincing; production RAG demands proof. A golden eval set, RAGAS faithfulness/context precision, and regression tests before release are the foundation so retriever or prompt changes do not silently degrade quality. This program installs the evaluation foundation on day one.

Security mapped to OWASP LLM Top 10 2025

Security module mapped explicitly to OWASP LLM01 prompt injection, LLM06 sensitive information disclosure, LLM08 vector & embedding weaknesses, and LLM09 misinformation, plus NIST AI RMF GenAI Profile (NIST AI 600-1) and UU PDP.

Most common mistake: jumping to vector DB without chunking & evaluation

Many teams busy themselves picking a vector database then become disappointed when answer quality stays low. Proper chunking, corpus-fit embedding, and a golden eval set matter more than DB choice. This program puts the right priority order in place.

AI Assistants That Answer from Company Documents

Enterprise RAG training is a technical program that equips engineering, data, and product teams to build retrieval-augmented generation for corporate LLM applications: from document chunking strategy, embedding model selection, indexing on vector databases (Pinecone, Weaviate, Qdrant, pgvector), LangChain/LlamaIndex orchestration, through quality evaluation with RAGAS and TruLens, with risk controls mapped to OWASP LLM Top 10 2025, NIST AI RMF GenAI Profile (NIST AI 600-1), and the obligations of Indonesia's Personal Data Protection Law (UU PDP No. 27/2022).

1Grounded in the seminal paper 'Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks' (Lewis et al. 2020) and current production practice of LangChain/LlamaIndex
2Covers the four RAGAS evaluation pillars: faithfulness, answer relevancy, context precision, context recall, plus TruLens triad monitoring
3Explicit mapping to OWASP LLM Top 10 2025: LLM01 prompt injection, LLM06 sensitive information disclosure, LLM08 vector & embedding weaknesses, LLM09 misinformation/hallucination
4Advanced chunking strategies: fixed-size, sentence/paragraph, semantic chunking, parent-document, recursive character splitter
5Case studies drawn from your own corpus: policies, SOPs, tickets, product docs
6Measurable outputs: one ready-to-iterate RAG prototype, golden eval set, RAGAS dashboard, and production blueprint
7Source material and tooling for this class: the original retrieval-augmented generation paper (Lewis et al. 2020), chunking strategy, embedding and vector database selection, LangChain and LlamaIndex orchestration, and evaluation using RAGAS and TruLens.

Measurable Outcomes

Expected Outcomes

Indicators mapped to Kirkpatrick L1-L4; qualitative targets set jointly during TNA. Every promise is one we can prove.

How a document assistant works is understood
All participants pass assessment on retrieve→augment→generate, chunking strategy, and embedding trade-offs. Measured through a review of the retrieve, augment, and answer flow (Kirkpatrick L2).
A working prototype by the end of the class
Each working group produces a functional RAG prototype by end of the intensive, integrated with corporate corpus. Seen in the prototype each group runs at the end of the class (Kirkpatrick L3).
Assistant answers are proven accurate
RAGAS faithfulness & context precision scores above the team-set baseline, measured on the golden eval set. Read from answer accuracy scores on the agreed test questions (Kirkpatrick L4).
Security guardrails are in place
Participants pass the OWASP LLM Top 10 2025 checklist for the RAG architecture they built. Checked against the language model security checklist (Kirkpatrick L2).
A design ready to take to production
Deployment documentation, observability (TruLens/Langfuse), and index refresh SOP approved by IT/security. It takes the form of a design document the security team signs off (Kirkpatrick L3 transfer).
Monetary value per use case (optional)
Per-use-case net benefit calculation isolated from other factors, when finance requests it. Per use case value in rupiah rests on Phillips L5 when asked.

FAQ

Frequently Asked Questions

Online tutorials stop at a notebook prototype with a small PDF corpus. This training addresses the problems that emerge when RAG meets a real corporate corpus: parsing complex documents, per-chunk data classification, hybrid search & reranker, structured evaluation with RAGAS, production observability, and OWASP LLM Top 10 2025 hardening. Case studies are drawn from your own corpus.

For most enterprise knowledge use cases, RAG is sufficient and more economical. Fine-tuning is considered when you need consistent stylistic change, strict structured output, or domain knowledge that cannot be retrieved. The curriculum covers a decision tree between prompt-only, RAG, fine-tune, and combinations with real criteria.

There is no universal choice. Selection criteria are discussed explicitly: cost (managed vs self-hosted), latency, hybrid search support, RBAC, data residency. We train the trade-offs of Pinecone, Weaviate, Qdrant, Milvus, and pgvector. Final selection is decided post-TNA with input from security & infrastructure teams.

With a golden eval set built with internal subject matter experts + evaluation frameworks: RAGAS (faithfulness, answer relevancy, context precision, context recall) and TruLens triad (context relevance, groundedness, answer relevance). Scores become baseline; retriever / prompt changes are regression-tested against this baseline before release.

Three layers: (1) per-chunk data classification before entering the index; (2) ACLs on the vector store so retrieval honours user role; (3) embedding & generation use private endpoints (private VPC, on-prem, or enterprise tier with no-training-on-data). Explicit mapping to OWASP LLM06 and LLM08, plus UU PDP obligations, is in the security module.

Depends on corpus complexity & integration. Common pattern: ready-to-iterate prototype at end of 3-5 day intensive; limited production pilot within 1-3 months with office hours; full production with SLA can take 3-6 months for complex use cases. Roadmap is set at TNA.

Yes. The 'Orchestration & Advanced Retrieval Patterns' module covers agentic RAG: router, query planner, multi-hop, self-correcting RAG (RAG-Fusion, Self-RAG, CRAG). Includes OWASP LLM06 excessive agency: safe boundaries when a RAG agent can call tools or write to systems.

Yes. We train multilingual embedding selection that performs well for Indonesian (multilingual-e5, BGE-M3), reranker tokenisation challenges for Indonesian, and query expansion techniques for synonyms/acronyms common in your domain. Case studies are conducted with real Indonesian-language corpora.

The governance module maps RAG components to ISO/IEC 42001: AI policy, AI impact assessment, roles & responsibilities, audit log, risk management, continual improvement. Output: a RAG governance blueprint attachable to the organisation's AI Management System documentation.

Yes. The report covers attendance, technical assessment scores, lab results, per-group golden eval scores, and recommendations for L&D and VP Engineering, mapped to Kirkpatrick levels. Engineers who complete the RAG lab can have an attendance certificate with a competency summary issued on request.

The state of the documents decides most of it, since a tidy archive is a world away from a pile of scans that need cleaning first. Next comes the question of whether the class runs on your internal documents, because that requires arranging access and masking sensitive information. Participant seniority, headcount, the number of groups and how often they meet, the lab environment with its compute resources, the venue, and whichever city hosts it complete the sum. We share the figure after a training needs analysis reviews your archive.

One prototype is built by small groups of 8 to 20 participants, and your twenty stay a single cohort. Five full days is enough for that prototype to run with its answer quality measured. What most often moves the dates is document preparation along with access approval, so handle that part well before day one. Lifting it into a service people use daily takes additional time after the class.

They can. This class calls for an instructor who has wrestled with messy corporate archives, because that is where the real problems surface. Send it straight to the programme coordinator; a validated document assistant instructor then joins the class. Lab modules, environment configuration, the test question set, and each group progress are saved inside our operations system, so the group carries on without setting up again.
