Harpreet Sahota 🥑

i'm gonna be at Open Data Science Conference (ODSC) AI West on Oct 29 in SF doing a workshop on visual ai and understanding your dataset using VLMs, embeddings

we're using vehicle damage detection as the example - working with the CarDD dataset to detect dents, scratches, cracks, all that stuff. 

basically showing how to actually build and evaluate these systems with fiftyone.

if you wanna learn how to properly work with visual AI models, come through:

🤖 Hacker-in-Residence @ Voxel51| 👨🏽‍💻 AI/ML Engineer | 👷🏽‍♀️ Technical Developer Advocate | Learn. Do. Write. Teach. Repeat.

alright so NVIDIA asked me to let you know about their new AI certifications and they're actually worth looking at if you're trying to level up

what's happening: there's a webinar on Oct 7 at 9am PT about how to prep for these certs. 

they're covering their associate and professional level exams including the new agentic AI one which actually looks pretty solid. 

it covers multi-agent systems, distributed reasoning, all the stuff you'd actually need to know.

I know certs can be hit or miss, but these ones focus on practical skills beyond just theory. 

they cover generative ai, multimodal systems, and the new professional ones go deep into LLM training, fine-tuning, and building agentic systems.

if you're already building this stuff, it's validation.  if you're trying to break in, it's a structured way to learn what matters.

the deal:

• use code "HarpreetS20" for 20% off any certification exam

• i've got 3 free self-paced training codes to give away. first three people to like, repost, and comment "jensen please bless me with vram" get them

learn more:

• webinar link: https://nvda.ws/42LQxCD 

• cert info: https://nvda.ws/42aOJmz

this may, or may not, help me get another gpu...though i certainly hope it does

Open article: Certification Programs by nvda.ws

when you've got 10k+ images, manually checking them isn't gonna work.

how do you actually know what's in your dataset? 

which samples are duplicates? 

which ones are actually useful? 

are there quality issues you're missing?

embeddings basically give you x-ray vision for visual data - you can see patterns, search semantically, and actually clean your dataset properly.

wrote about this for Open Data Science Conference (ODSC) - showing how to use @Voxel51 FiftyOne Brain's embedding methods to:

- visualize hidden patterns and find similar images

- detect duplicates and identify unique samples

- catch data leaks before they mess up your eval

once you start using embeddings like this, your dataset stops being a black box.

also if you're at ODSC AI West on Oct 29, i'm doing a session on "Mastering Visual AI with Vision-Language Models and Advanced Evaluation Techniques" where i will go deeper into this stuff.

Why does everyone act like OCR is a new capability of VLMs? anyways, nanonets integrated into fiftyone.

i just integrated 6 visual document retrieval models into fiftyone as remote zoo models

these are all available as remote source zoo models now. here's what they do:

• nomic-embed-multimodal (3b and 7b) https://lnkd.in/gZ3QGmPb

qwen2.5-vl base, outputs 3584-dim single vectors. currently the best single-vector model on vidore-v2. no ocr needed.

good for: single-vector retrieval when you want top performance

• bimodernvbert
https://lnkd.in/g_5DURCN

250m params, 768-dim single vectors. runs fast on cpu - about 7x faster than comparable models.

good for: when you need speed and don't have a gpu

• colmodernvbert
https://lnkd.in/gPM6KS6B

same 250m base as above but with colbert-style multi-vectors. matches models 10x its size on vidore benchmarks.

good for: fine-grained document matching with maxsim scoring

• jina-embeddings-v4
https://lnkd.in/g_q4tbYV

3.8b params, supports 30+ languages. has task-specific lora adapters for retrieval, text-matching, and code. does both single-vector (2048-dim) and multi-vector modes.

good for: multilingual document retrieval across different tasks

• colqwen2-5-v0-2
https://lnkd.in/g6aaRbWs

qwen2.5-vl-3b with multi-vectors. preserves aspect ratios, dynamic resolution up to 768 patches. token pooling keeps ~97.8% accuracy.

good for: document layouts where aspect ratio matters

• colpali-v1-3
https://lnkd.in/g8rZ4awD

paligemma-3b base, multi-vector late interaction. the original model that showed visual doc retrieval could beat ocr pipelines.

good for: baseline multi-vector retrieval, well-tested

register the repos as remote zoo sources, load the models, compute embeddings. works with all fiftyone brain methods.
