Algorithmic Regularization in Over-parameterized Matrix Sensing and Neural Networks with Quadratic Activations

Yuanzhi Li, Tengyu Ma and Hongyang Zhang, Algorithmic Regularization in Over-parameterized Matrix Sensing and Neural Networks with Quadratic Activations, COLT 18, Best Paper Award.

We show that the gradient descent algorithm provides an implicit regularization effect in the learning of over-parameterized matrix factorization models and one-hidden-layer neural networks with quadratic activations.  

Concretely, we show that given ˜O(dr2) random linear measurements of a rank r positive semidefinite matrix X⋆, we can recover X⋆ by parameterizing it by UU⊤ with U ∈ Rd×d and minimizing the squared loss, even if r ≪ d. We prove that starting from a small initialization, gradient descent recovers X⋆ in ˜O(√r) iterations approximately. The results solve the conjecture of Gunasekar et al. [16] under the restricted isometry property. 

The technique can be applied to analyzing neural networks with one-hidden-layer quadratic activations with some technical modifications.

GOLF 學用接軌聯盟

顏和正，科技大老不談生意　打一場沒有輸家、只有贏家的「GOLF」，天下雜誌，680 期，2019-08-27

這不是場慈善球賽，而是友達、緯創資通與仁寶電腦3家科技大廠，在去年共同成立的「學用接軌聯盟」GOLF（Gap of Learning & Field）。這個提供學生線上專業課程先修、線下實習機會的O2O平台，整合了全台21家企業與42所大學，就是為了創造產學接軌、青年培力、擴大企業人才庫的「三贏」。 

「跟打高爾夫球無關，取名是希望凸顯『產學接軌』的概念。企業需求在平台上展現，學校與學生會對企業需求有預先認知，課程設計與未來就業比較容易，」彭双浪指出這場「產學高爾夫」的贏家，就是學校、學生與企業。

 近年來，自動駕駛成為各大車廠、科技巨頭競逐的領域，從半自駕（先進輔助駕駛）到全自駕（完全無人駕駛），應用的科技包括傳感技術、機器人學、機器知覺、機器學習、人工智慧、演算法和智慧型運輸系統等等，原本在學術領域的知識逐漸實用化、商品化。
