Peek2: Regex-free Byte-level Byte-Pair Encoding Pretokenizer for LLM Inference on Edge Devices

Liu Zai, Iraklis Klampanos

Pretokenization is a crucial, sequential pass in Byte-level BPE tokenizers, yet little work has been done to optimize it for edge-side inference. Our proposed new implementation, P…

WeLa-VAE: Learning Alternative Disentangled Representations Using Weak Labels

Vasilis Margonis, Athanasios Davvetas, Iraklis A. Klampanos

Learning disentangled representations without supervision or inductive biases, often leads to non-interpretable or undesirable representations. On the other hand, strict supervisio…

Unsupervised Severe Weather Detection Via Joint Representation Learning Over Textual and Weather Data

Athanasios Davvetas, Iraklis A. Klampanos

When observing a phenomenon, severe cases or anomalies are often characterised by deviation from the expected data distribution. However, non-deviating data samples may also implic…

Learning Improved Representations by Transferring Incomplete Evidence Across Heterogeneous Tasks

Athanasios Davvetas, Iraklis A. Klampanos

Acquiring ground truth labels for unlabelled data can be a costly procedure, since it often requires manual labour that is error-prone. Consequently, the available amount of labell…

Evidence Transfer for Improving Clustering Tasks Using External Categorical Evidence

Athanasios Davvetas, Iraklis A. Klampanos, Vangelis Karkaletsis

In this paper we introduce evidence transfer for clustering, a deep learning method that can incrementally manipulate the latent representations of an autoencoder, according to ext…

The Design of a Community Science Cloud: The Open Science Data Cloud Perspective

Robert L. Grossman, Matthew Greenway, Allison P. Heath +9

In this paper we describe the design, and implementation of the Open Science Data Cloud, or OSDC. The goal of the OSDC is to provide petabyte-scale data cloud infrastructure and re…
