Today, we are excited to announce support for dimensionality reduction using principal components analysis (PCA) in Amazon SageMaker Data Wrangler. Amazon SageMaker Data Wrangler reduces the time it takes to aggregate and prepare data for machine learning (ML) from weeks to minutes. With Data Wrangler, you can simplify the process of data preparation and feature engineering, and complete each step of the data preparation workflow, including data selection, cleansing, exploration, and visualization from a single visual interface. PCA is a popular technique for analyzing large datasets containing a high number of dimensions per observation and is a helpful statistical technique for reducing the dimensionality of a dataset for use with popular ML algorithms like XgBoost and random forest. Previously, to perform PCA on a data set, data scientists would have to find appropriate libraries and write code to reduce high-dimensional data.

Today, we are excited to announce the ability to dynamically support different datasets stored on S3 through use of parameters in Amazon SageMaker Data Wrangler. Amazon SageMaker Data Wrangler reduces the time it takes to aggregate and prepare data for machine learning (ML) from weeks to minutes. With Data Wrangler, you can simplify the process of data preparation and feature engineering, and complete each step of the data preparation workflow, including data selection, cleansing, exploration, and visualization from a single visual interface. Previously, customers did not have an easy way to dynamically refer to data sets when running Data Wrangler processing jobs on a schedule. Customers also lacked a way to more easily filter down files in an S3 bucket to be used for processing. Finally, customers lacked a simple way to change data sources when running a Data Wrangler processing job from the Create Job workflow or from a Data Wrangler processing notebook.

There was once a guy who said he felt he had been “put out to pasture” at the age of 52. He had been running TI’s semiconductor division but was then transferred to the company’s less than successful consumer business, and later to a staff job. He then founded a company which, last year, had …

Cree is aiming at premium indoor and outdoor lighting with a family of metal-substrate CoBs called CMB, tuned as performance upgrades from its CXA, CXB and CMA families, while retaining mechanical and optical compatibility. “Up to 8% improvement in lumens/W vs previous generations by leveraging the latest technology platform,” is the company’s claim. They are …

Even with the one week transition period, Liz is the shortest-serving post-war prime minister, going down as one of, if not the least successful and popular leaders of the country. Even extending the ranking to cover all PMs, Truss would still be at the top by a considerable margin. Before Liz’s departure , Boris had …

Innoscience has brought out a range of 650V E-mode GaN HEMT devices. New 190mΩ, 350mΩ and 600mΩ RDS(on) devices in industry-standard 8×8 and 5×6 DFN packages join previously-announced 140mΩ, 240mΩ and 500mΩ RDS(on) parts, creating a significant portfolio of available devices. The 650V HEMTs are all qualified to JEDEC standards for chip and package. More, …

At the 75th IEDM from December 3rd to the 7th in San Francisco, TSMC is giving a paper on a 2D nanosheet GAA transistor. The transistor with a 40nm gate width produced a drive current of 410microamps per micron at Vds of 1V. TSMC uses a transition-metal dichalcogenide monolayer for the semiconducting channel in a …
