【南宋】 陈与义

忆昔午桥桥上饮，坐中多是豪英。长沟流月去无声。杏花疏影里，吹笛到天明。

二十余年如一梦，此身虽在堪惊。闲登小阁看新晴。古今多少事，渔唱起三更。

【南宋】 陈与义

张帆欲去仍搔首，更醉君家酒。吟诗日日待春风，及至桃花开后却匆匆。

歌声频为行人咽，记着樽前雪。明朝酒醒大江流，满载一船离恨向衡州。

【南宋】 陈与义

高咏楚词酬午日，天涯节序匆匆。榴花不似舞裙红。无人知此意，歌罢满帘风。

万事一身伤老矣，戎葵凝笑墙东。酒杯深浅去年同。试浇桥下水，今夕到湘中。

【南宋】 蒋捷

我梦唐宫春昼迟，正舞到、曳裾时。翠云队仗绛霞衣，慢腾腾，手双垂。

忽然急鼓催将起，似彩凤、乱惊飞。梦回不见万琼妃，见荷花，被风吹。

【唐】 元稹

寥落古行宫，宫花寂寞红。

白头宫女在，闲坐说玄宗。

TL;DR: - For categorical outcomes (e.g., classification), the negative log-likelihood corresponds to the cross-entropy loss. - For continuous outcomes (e.g., regression), assuming a Gaussian distribution, the negative log-likelihood corresponds to the Mean Squared Error (MSE) loss.

In this section we define the notion of a function, a special type of relation.

In 3-D Euclidean space, a sphere can be locally approximated as a plane. The proof is as follows.
