AI-generated text boundary detection with RoFT

no code implementations14 Nov 2023 Laida Kushnareva, Tatiana Gaintseva, German Magai, Serguei Barannikov, Dmitry Abulkhanov, Kristian Kuznetsov, Eduard Tulchinskii, Irina Piontkovskaya, Sergey Nikolenko

Due to the rapid development of large language models, people increasingly often encounter texts that may start as written by a human but continue as machine-generated.

Disentanglement Learning via Topology

no code implementations24 Aug 2023 Nikita Balabin, Daria Voronkova, Ilya Trofimov, Evgeny Burnaev, Serguei Barannikov

We propose TopDis (Topological Disentanglement), a method for learning disentangled representations via adding multi-scale topological loss term.

Intrinsic Dimension Estimation for Robust Detection of AI-Generated Texts

1 code implementation NeurIPS 2023 Eduard Tulchinskii, Kristian Kuznetsov, Laida Kushnareva, Daniil Cherniavskii, Serguei Barannikov, Irina Piontkovskaya, Sergey Nikolenko, Evgeny Burnaev

Rapidly increasing quality of AI-generated content makes it difficult to distinguish between human and AI-generated texts, which may lead to undesirable consequences for society.

Learning Topology-Preserving Data Representations

1 code implementation31 Jan 2023 Ilya Trofimov, Daniil Cherniavskii, Eduard Tulchinskii, Nikita Balabin, Evgeny Burnaev, Serguei Barannikov

The method aims to provide topological similarity between the data manifold and its latent representation via enforcing the similarity in topological features (clusters, loops, 2D voids, etc.)

Topological Data Analysis for Speech Processing

no code implementations30 Nov 2022 Eduard Tulchinskii, Kristian Kuznetsov, Laida Kushnareva, Daniil Cherniavskii, Serguei Barannikov, Irina Piontkovskaya, Sergey Nikolenko, Evgeny Burnaev

We apply topological data analysis (TDA) to speech classification problems and to the introspection of a pretrained speech model, HuBERT.

Artificial Text Detection via Examining the Topology of Attention Maps

2 code implementations EMNLP 2021 Laida Kushnareva, Daniil Cherniavskii, Vladislav Mikhailov, Ekaterina Artemova, Serguei Barannikov, Alexander Bernstein, Irina Piontkovskaya, Dmitri Piontkovski, Evgeny Burnaev

The impressive capabilities of recent generative models to create texts that are challenging to distinguish from the human-written ones can be misused for generating fake news, product reviews, and even abusive content.

Topological obstructions in neural networks learning

no code implementations31 Dec 2020 Serguei Barannikov, Daria Voronkova, Ilya Trofimov, Alexander Korotin, Grigorii Sotnikov, Evgeny Burnaev

We define the neural network Topological Obstructions score, "TO-score", with the help of robust topological invariants, barcodes of the loss function, that quantify the "badness" of local minima for gradient-based optimization.

Barcodes as summary of objective function's topology

no code implementations29 Nov 2019 Serguei Barannikov, Alexander Korotin, Dmitry Oganesyan, Daniil Emtsev, Evgeny Burnaev

We apply the canonical forms (barcodes) of gradient Morse complexes to explore topology of loss surfaces.
