The study establishes a correlation between image generation quality and classification accuracy, showing their generative model contains features competitive with top convolutional networks in unsupervised learning.
OpenAI has announced the release of an API that will provide developers access to their new AI models. This move opens up OpenAI's latest AI capabilities to third-party developers and applications through a programmatic interface.
A new analysis reveals that compute requirements for training neural networks to match ImageNet classification performance have decreased by 50% every 16 months since 2012. Training a network to AlexNet-level performance now requires 44 times less compute than in 2012, far outpacing Moore's Law improvements which would only yield 11x cost reduction over the same period.
Ethereum 2.0 development team released v0.10.0 spec as a stable target for multi-client testnets and security reviews in early 2020. The Lighthouse team is actively building infrastructure while planning a relaunch of testing networks.
Ethereum 2.0 development continues to progress with multiple new testnets coming online and comprehensive Phase 0 specifications being announced. The update indicates significant technical advancement in the eth2 transition, though substantial work remains to be completed.
Research reveals that deep learning models including CNNs, ResNets, and transformers exhibit a double descent phenomenon where performance improves, deteriorates, then improves again as model size, data size, or training time increases. This universal behavior can be mitigated through proper regularization, though the underlying mechanisms remain unclear and require further investigation.
The Ethereum network is scheduled to undergo the Istanbul upgrade at block 9,069,000, predicted for December 7, 2019. This scheduled network upgrade represents a significant technical milestone for the Ethereum blockchain infrastructure.
