日常英语---200720,tensorflow2优化函数:model.compile(optimizer='adam',loss='binary_crossentropy',metrics=['acc']

一、总结

一句话总结:

metrics:英 /ˈmetrɪks/ :n. 度量;作诗法;韵律学

1、area读音?

英 /ˈeəriə/

2、Requests is an elegant and simple HTTP library for Python, built for human beings.?

elegant:英 /ˈelɪɡənt/ :adj. 高雅的,优雅的;讲究的;简炼的;简洁的

3、The Session object allows you to 【persist certain】parameters across requests. It also persists cookies across all requests made from the Session instance, and will use urllib3’s connection pooling. ?

persist:英 /pəˈsɪst/:vt. 坚持说,反复说
certain:英 /ˈsɜːtn/ :adj. 某一;必然的;确信;无疑的;有把握的

Session对象允许您在请求中保留某些参数。 它还会在会话实例发出的所有请求中保留cookie,并将使用urllib3的连接池。

4、python爬虫库Requests的response对象的iter_content(chunk_size=1, decode_unicode=False)方法?

chunk:英 /tʃʌŋk/:n. 大块;矮胖的人或物

Iterates over the response data. When stream=True is set on the request, this avoids reading the content at once into memory for large responses. The chunk size is the number of bytes it should read into memory. This is not necessarily the length of each item returned as decoding can take place.

chunk_size must be of type int or None. A value of None will function differently depending on the value of stream. stream=True will read data as it arrives in whatever size the chunks are received. If stream=False, data is returned as a single chunk.

If decode_unicode is True, content will be decoded using the best available encoding based on the response.

5、sample读音?

sample:英 /ˈsɑːmpl/ :n. 样品,样本;

6、exit读音?

exit:英 /ˈeksɪt; ˈeɡzɪt/ :n. 出口,通道;退场

7、SymPy有三个内建的数值类型:实数,有理数和整数。有理数类用两个整数来表示一个有理数。分子与分母,所以Rational(1,2)代表1/2,Rational(5,2)代表5/2,等等。?

rational:英 /ˈræʃnəl/:adj. 合理的;理性的 n. 有理数

8、SymPy中(x/y).subs([(x, 0), (y, 0)], simultaneous=True)?

simultaneous:英 /ˌsɪmlˈteɪniəs/ :adj. 同时的;联立的;同时发生的

9、比如机器模型每次训练的【准确度】?

accuracy:英 /ˈækjərəsi/ :n. [数] 精确度,准确性

10、plt.plot(history.epoch,history.history.get('loss'))?

epoch:英 /ˈiːpɒk/:n. [地质] 世;新纪元;新时代

11、matplotlib画散点图:plt.scatter(data.Education,data.Income)?

scatter:英 /ˈskætə(r)/ :v. 撒播;散开 n. 零星散布的东西:

12、tensorflow2模型创建:model = tf.keras.Sequential()?

sequential:英 /sɪˈkwenʃl/ :adj. 连续的;相继的
