Focus Your Attention (with Adaptive IIR Filters)

no code implementations24 May 2023 Shahar Lutati, Itamar Zimerman, Lior Wolf

We present a new layer in which dynamic (i. e., input-dependent) Infinite Impulse Response (IIR) filters of order two are used to process the input sequence prior to applying conventional attention.

Separate And Diffuse: Using a Pretrained Diffusion Model for Improving Source Separation

no code implementations25 Jan 2023 Shahar Lutati, Eliya Nachmani, Lior Wolf

Applying a diffusion model Vocoder that was pretrained to model single-speaker voices on the output of a deterministic separation model leads to state-of-the-art separation results.

OCD: Learning to Overfit with Conditional Diffusion Models

1 code implementation2 Oct 2022 Shahar Lutati, Lior Wolf

We present a dynamic model in which the weights are conditioned on an input sample x and are learned to match those that would be obtained by finetuning a base model on x and its label y.

SepIt: Approaching a Single Channel Speech Separation Bound

no code implementations24 May 2022 Shahar Lutati, Eliya Nachmani, Lior Wolf

We present an upper bound for the Single Channel Speech Separation task, which is based on an assumption regarding the nature of short segments of speech.

HyperHyperNetworks for the Design of Antenna Arrays

1 code implementation9 May 2021 Shahar Lutati, Lior Wolf

Our experiments demonstrate that our approach is able to design novel antennas and antenna arrays that are compliant with the design requirements, considerably better than the baseline methods.
