The user is seeking guidance on resources to bridge this knowledge gap and effectively apply VAEs in a semi-unsupervised setting.

    Conceptually I understand neural networks, back propagation, etc, but I have ZERO experience with Keras, PyTorch, and TensorFlow. And when I read code samples, it seems vastly different than any modeling pipeline based in scikit-learn.

    Alignment Forum

    Analysis

    Google DeepMind's mech interp team is releasing Gemma Scope 2, a suite of Sparse Autoencoders (SAEs) and transcoders trained on the Gemma 3 model family. This release offers advancements over the previous version, including support for more complex models, a more comprehensive release covering all layers and model sizes up to 27B, and a focus on chat models. The release includes SAEs trained on different sites (residual stream, MLP output, and attention output) and MLP transcoders. The team hopes this will be a useful tool for the community despite deprioritizing fundamental research on SAEs.

    Key Takeaways

    Reference

    The release contains SAEs trained on 3 different sites (residual stream, MLP output and attention output) as well as MLP transcoders (both with and without affine skip connections), for every layer of each of the 10 models in the Gemma 3 family (i.e. sizes 270m, 1b, 4b, 12b and 27b, both the PT and IT versions of each).

    MarkTechPost

    Analysis

    This article announces the open-sourcing of Meta AI's Perception Encoder Audiovisual (PE-AV), a new family of encoders designed for joint audio and video understanding. The model's key innovation lies in its ability to learn aligned audio, video, and text representations within a single embedding space. This is achieved through large-scale contrastive training on a massive dataset of approximately 100 million audio-video pairs accompanied by text captions. The potential applications of PE-AV are significant, particularly in areas like multimodal retrieval and audio-visual scene understanding. The article highlights PE-AV's role in powering SAM Audio, suggesting its practical utility. However, the article lacks detailed information about the model's architecture, performance metrics, and limitations. Further research and experimentation are needed to fully assess its capabilities and impact.

    Analysis

    This article likely presents a comparative analysis of two dimensionality reduction techniques, Proper Orthogonal Decomposition (POD) and Autoencoders, in the context of intraventricular flows. The 'critical assessment' suggests a focus on evaluating the strengths and weaknesses of each method for this specific application. The source being ArXiv indicates it's a pre-print or research paper, implying a technical and potentially complex subject matter.
