Responsibilities
Investigate saliency and activation mapping techniques on different forms of audio representations, e.g, spectrograms and acoustic features (e.g. pitch, formants)
Build insights for decision attribution on audio inputs, e.g., most impactful segments within an audio sample towards a classification outcome
Prepare an explainable-AI library for generative audio detection models
Propose novel end-to-end solutions for attribution/explainability and use them to improve detection models
Collaborate with scientists and engineers across the organization
About You
Currently enrolled in a Masters or PhD program in deep learning, computer vision, speech/audio processing, or a related field - Implemented and/or published peer-reviewed papers in reputable AI research venues such as CVPR, ICLR, Interspeech
Have 1+ years of hands-on experience with model interpretation tools, e.g., saliency maps, attention maps, Grad-CAM, SHAP.
Have 1+ years of programming experience in Python and model building in PyTorch; experience with audio models, e.g. HuBERT/wav2vec, would be a plus but not essential.
