AI milestones in 2019
5 documented milestones from 2019.
OpenAI Released the Full 1.5-Billion-Parameter GPT-2 Model
In November 2019, OpenAI released the full 1.5-billion-parameter version of GPT-2, completing a staged release the organisation had begun in February 2019 with a smaller variant, citing concerns about potential misuse of a model capable of generating coherent long-form text.
Facebook AI Research Releases Detectron2
In October 2019, Facebook AI Research released Detectron2, an open-source object detection and segmentation framework built on PyTorch, supporting algorithms including Mask R-CNN, DensePose, and panoptic feature pyramid networks, replacing the earlier Caffe2-based Detectron.
Textron Systems Unveils Ripsaw M5 Robotic Combat Vehicle
In October 2019, Textron Systems unveiled the Ripsaw M5 Robotic Combat Vehicle at the Association of the United States Army Annual Meeting in Washington, D.C., demonstrating an unmanned ground vehicle with autonomous navigation, 360-degree situational awareness, and configurable mission payloads.
Google AI Model Matches or Exceeds Radiologist Performance in Lung Cancer Detection from CT Scans
In May 2019, researchers at Google Health and Northwestern Medicine published a deep-learning model in Nature Medicine that detected malignant lung nodules in low-dose CT scans, matching or exceeding the performance of six radiologists on a held-out dataset, with fewer false positives and false negatives when prior scans were unavailable.
Analogue resistive memory circuit solves linear algebra problems in one step
In March 2019, Daniele Ielmini and colleagues at Politecnico di Milano published results in PNAS demonstrating a crosspoint resistive-memory circuit that solves linear systems, matrix eigenvector problems, and differential equations by physical analogue relaxation, substantially reducing the energy and latency costs of conventional iterative digital solvers.
