AMD now supports Google’s Gemma 4 models (2B–31B parameters) across its entire hardware lineup, including Instinct GPUs (datacenters), Radeon GPUs (workstations), and Ryzen AI processors (PCs). The integration is compatible with vLLM, SGLang, llama.cpp, Ollama, and Lemonade Server, aiming to optimize AI performance for both cloud and local deployment.
Google is accusing others of cloning its Gemini AI, despite its own history of scraping data without permission to train its models. This raises questions of hypocrisy as companies compete to protect their AI investments and differentiate their offerings, facing challenges like model distillation and the potential for smaller entities to compete.
This post introduces **GIST (Greedy Independent Set Thresholding)**, a new algorithm for selecting diverse and useful data subsets for machine learning. GIST tackles the NP-hard problem of balancing diversity (minimizing redundancy) and utility (relevance to the task) in large datasets.
**Key points:**
* **Approach:** GIST prioritizes minimum distance between selected data points (diversity) then uses a greedy algorithm to approximate the highest-utility subset within that constraint, testing various distance thresholds.
* **Guarantee:** GIST is guaranteed to find a subset with at least half the value of the optimal solution.
* **Performance:** Experiments demonstrate GIST outperforms existing methods (Random, Margin, k-center, Submod) in image classification and single-shot downsampling.
* **Application:** Already used to improve video recommendation diversity at YouTube.
**GIST provides a mathematically grounded and efficient solution for selecting high-quality data subsets for machine learning, crucial as datasets scale.**

AlexNet, a groundbreaking neural network developed in 2012 by Alex Krizhevsky, Ilya Sutskever, and Geoffrey Hinton, has been released in source code form by the Computer History Museum in collaboration with Google. This model significantly advanced the field of AI by demonstrating a massive leap in image recognition capabilities.
The paper titled "Attention Is All You Need" introduces the Transformer, a novel architecture for sequence transduction models that relies entirely on self-attention mechanisms, dispensing with traditional recurrence and convolutions. Key aspects of the model include:
- Architecture: The Transformer consists of an encoder-decoder structure, with both components utilizing stacked layers of multi-head self-attention mechanisms and feed-forward networks. It avoids recurrence and convolutions, allowing for greater parallelism and faster training.
- Attention Mechanism: The model uses scaled dot-product attention for computing attention scores, which scales down the dot products to prevent softmax from saturating.
- Multi-head attention is employed to allow the model to attend to information from different representation subspaces at different positions.
- Training and Regularization: The authors use the Adam optimizer with a particular learning rate schedule that initially increases the rate and then decreases it based on the number of training steps. They also employ techniques like dropout and label smoothing to regularize the model during training.
- Performance: The Transformer achieves state-of-the-art results on machine translation benchmarks (WMT 2014 English-to-German and English-to-French), outperforming previous models with significantly less training time and computational resources.
- Generalization: The model demonstrates strong performance on tasks other than machine translation, such as English constituency parsing, indicating its versatility and ability to learn complex dependencies and structures.
The paper emphasizes the efficiency and scalability of the Transformer, highlighting its potential for various sequence transduction tasks, and provides a foundation for subsequent advancements in natural language processing and beyond.
