AI Factory Glossary

retrieval augmentation, prompting techniques

Retrieval augmentation supplements prompts with relevant information from knowledge bases.

retrieval augmentation,rag

General term for enhancing LLM outputs with retrieved external information.

retrieval head, rag

Retrieval heads identify which retrieved documents were actually used.

retrieval head,rag

Specialized attention head for deciding when to retrieve.

retrieval latency, rag

Time to retrieve documents.

retrieval metrics, evaluation

Evaluate retrieval quality.

retrieval precision, rag

Retrieval precision measures fraction of retrieved documents that are relevant.

retrieval recall, rag

Retrieval recall measures fraction of relevant documents that are retrieved.

retrieval throughput, rag

Queries processed per second.

retrieval-augmented generation pipeline, rag

Full RAG system.

retrieval-augmented language models, rag

Use retrieved documents to inform generation.

retrieval-based demonstration,prompt engineering

Select relevant examples from pool using similarity.

retrieval-free segments, rag

Parts of answer not requiring retrieval.

retrieval-interleaved generation,rag

Alternate between retrieval and generation multiple times.

retro (retrieval-enhanced transformer),retro,retrieval-enhanced transformer,llm architecture

Architecture designed for retrieval augmentation.

retrograde well, process integration

Retrograde wells have peak doping below surface providing better punchthrough resistance and reduced junction capacitance.

retrograde well,process

Well with higher doping deeper down.

retrospective,post mortem,improve

Regular retros on AI projects. What worked, what did not, what to improve. Continuous learning culture.

retrosynthesis planning, chemistry ai

Plan synthetic routes backward from target.

retry logic, llm optimization

Retry logic attempts failed requests again with exponential backoff.

retry logic,exponential,backoff

Retry on transient failures with exponential backoff. Jitter prevents thundering herd.

retry logic,software engineering

Automatically retry failed operations.

retry,backoff,resilience

Retry failed requests with exponential backoff. Add jitter to avoid thundering herd. Set max retries and timeouts.

return line, manufacturing equipment

Return lines recirculate unused chemicals back to reservoirs.

return loss, signal & power integrity

Return loss measures signal reflection magnitude indicating impedance matching quality.

return material analysis, rma, quality

Analyze returned failed units.

return to vendor, quality

Send defective material back to supplier.

revenue ramp, business

Increase sales over time.

reverse body bias (rbb),reverse body bias,rbb,design

Reduce leakage by raising threshold.

reverse body bias, design & verification

Reverse body bias raises threshold voltage reducing leakage at cost of performance.

reverse bonding, packaging

Bond to substrate first.

reverse osmosis, environmental & sustainability

Reverse osmosis purifies water by forcing it through semipermeable membranes removing dissolved solids.

reverse tone imaging,lithography

Use negative resist with positive mask (or vice versa).

reversible layers, optimization

Invertible transformations saving memory.
