At this year's ER advances on knowledge graphs, AI - esp. LLMs - and core conceptual modeling subjects are discussed. Highly interesting topics. My research is an exploratory approach to combine modeling with LLMs by a Conceptual Model Interpreter: https://t.co/w7F0oUbVev

[ER Conference Series @ERconf]

#ER2023 has officially started today, thank you all for joining with productive discussions!

We are looking forward to tomorrow, with the keynotes by Maurizio Lenzerini and Catia Pesquita, the main track/forum papers, and the Doctoral Consortium. Then... a tasty dinner!

[Felix Härer @fhaerer]

I'm excited and also grateful to announce that my paper, "Scalable Model-Based Decentralized Applications in the Cloud Using Certificates and Blockchains", has been published with the IEEE PKIA 2023 Proceedings and won the Best Paper Award. https://t.co/8KckSgsT9o

Our workshop B4TDS - 3rd ​International Workshop on Blockchain for Trusted Data Sharing - organized by Alessandro Marcelletti and myself took place today at the BIR Business Informatics Research Conference hosted by @UniCamerino in Ascoli Piceno! https://t.co/TRGrCbnNqM

[Felix Härer @fhaerer]

It was an honour to contribute a paper at this year's PKIA conference and receive a recognition (best paper award) for it. Highly interesting talks on PKI, zero knowledge, CBDC (=> https://t.co/RAEYWwj6f6). My paper on decentralized applications I'll share when published by IEEE.

[Felix Härer @fhaerer]

Blockchain contributions welcome: the submission date for the 3rd Int. Workshop on Blockchain for Trusted Data Sharing (B4TDS@BIR 2023) has been extended to July 21. Looking forward to novel ideas and interesting discussions at BIR 2023 in Ascoli Piceno, IT!

[Felix Härer @fhaerer]

Blockchain research to share? The 3rd Int. Workshop on Blockchain for Trusted Data Sharing, B4TDS@BIR 2023 in Ascoli Piceno, IT is open for submissions until July 11. Workshop: Sept. 15, organized by Alessandro Marcelletti (University of Camerino) and me. https://t.co/JO65Jgjp2D

Following Dolly, another open source AI with fine tuning by vast amounts of human input is now out. Based on Pythia, they started also with reinforcement learning from human feedback (RLHF) training. https://t.co/qVasShznEX / https://t.co/qCSx0PDTTJ / https://t.co/bjBXNSa273

OpenAssistant is officially released!

OpenAssistant is an open-source chat model. The release includes models, datasets, and a chat interface.

The dataset consists of a ~161K human-generated, human-annotated assistant-style conversation corpus, including 35 different languages and annotated with ~461K quality ratings. This dataset release is huge!

There are different models available including LLaMA-based and Pythia-based ones.

We have seen many chat models released in the past few weeks but this one is probably a lot more powerful in terms of conversational capabilities. Will be testing it out in the coming days.

Today, the Ethereum Shapella upgrade will be activated, a combination of two upgrades "Shanghai" on the execution layer and "Capella" on the consensus layer. They will bring slight efficiency and smart contract upgrades in addition to staking withdrawals https://t.co/HpCdKBiHNs.

GPT4All is another small and high quality open source model that can run on laptops and low-power PCs. What's special: it is trained from GPT 3.5. "We collected roughly one million prompt-response pairs using the GPT-3.5-Turbo OpenAI API" https://t.co/aV7RcsbBGb

Here are all the computations that ggml performs for inference of a single-layer LLaMA model

The full model inference is the same with extra repetitions of the inner part of this graph. So simple, yet so powerful
