另一个开始项目是按照项目书的要求,希望将一个材料的的性能提升到2mAh/cm2 。我的主要工作是协助师兄以涂敷的方法将将电极的制作达到加拿大28官网所需的要求。

继上周探究了EDTA在Cu离子无电沉积中的络合促进作用之后,加拿大28官网本周采用了两种新的理论可行的溶液,其与Cu离子分别络合成Cu(SCN)2和Cu-BTA。这两种新的溶液是从大约十年前的一篇文献上得到灵感的,但当加拿大28官网按照原始文献的实验方法重复实验时,效果却不尽如人意。虽然新的溶液在中性偏碱的情况下能达到很好的络合效果从而抑制Cu离子沉淀,但当pH调高至加拿大28官网所需的9.5以上时,其抑制效果远差于EDTA。加拿大28官网在此基础上比较了三种溶液的OCP实验结果,同样是EDTA远优于后两者。至于对EDTA的具体探究,加拿大28官网将在下周进一步完成。

一. Predicting Movie Ratings

1.1 Problem Formulation

  下图是四位用户对于五部电影的评分(若用户没有评分, 则用表示). 一些符号如下图右下角所示. 推荐系统就是通过已知的评分来判断未知的评分.
    

1.2 Content Based Recommendations

  假设每一部电影都对应一个特征向量, 如下图x1x1, x2x2所示. 对于第jj个用户, 加拿大28官网通过学习得到参数θθ. 这样, 这个用户对于第ii电影的评分就可以(θ(j))Tx(i)(θ(j))Tx(i)用来估计.

使用梯度下降来得到最优解(和线性回归相似).

上面是迁移好了并train好了的模型,它不仅训练了后面的 fc layers, 也保存了后面的 fc 参数。接着加拿大28官网提取原始的 VGG16 前半部分参数和 train 好的后半部分参数,并进行测试。

我将两张猫和老虎的图片输入,输出为长度。
