# "setdefault()" inserts into a dictionary only if the given key isn't present filled_dict.setdefault("five", 5) # filled_dict["five"] is set to 5 filled_dict.setdefault("five", 6) # filled_dict["five"] is still 5 我们可以使用update方法用另外一个dict来更新当前dict,比如a.update(b...
Upon execution, the above program returns false, as set "b" is not a subset of "a". False Here, we have two programs in both we have used issubset() method to check if "a" and "b" are subset of each other. Since all element of "a" are present in "b". so, output comes...

循环神经网络,然后hui用Theano(一个可以在GPU上进行运算的库)对实现进行优化。我会跳过一些对理解循环神经网络不是很重要的代码片段,但完整的代码可以在这里找到。 语言模型 这里的目标是用RNN构建一个语言模型,下面会解释一下什么是语言模型。假设有一个包含 ...
