def answer(a): """ Function for standardizing output results :param a:np_array:shape(10, m) """ k = np.argmax(a) output = np.zeros(a.shape) output[k] = 1 return output

这是一个用于标准化输出结果的函数。该函数接受一个形状为(10, m)的NumPy数组a作为输入。
首先,函数使用np.argmax()函数找到数组a中最大值所在的索引k。然后,创建一个与数组a形状相同的全零数组output。
接下来,将output中索引为k的位置设置为1,其余位置仍为0。这样就得到了一个只有最大值位置为1,其他位置为0的标准化输出结果。
最后,函数返回标准化后的output数组。
这种标准化输出结果的方式常用于多分类问题,其中输出层的每个节点表示一个类别,最大值所在的节点即表示模型预测的类别。通过将预测结果标准化为只有一个1和其他位置都为0的形式,方便进行模型评估和结果解读。

3.3 Normalizing Data
Normalization is the process of bringing all the data into a standard format. In our case, this involves standardizing the names of locations to ensure consistency and accuracy. The following steps were taken to normalize the data:
1. Removing diacritics: Diacritics are the accents and other marks that appear above or below letters in some languages. However, not all systems can handle these characters, so we removed them to ensure compatibility.
2. Converting to lowercase: To ensure consistency, all location names were converted to lowercase.
3. Removing punctuation: Punctuation marks were removed from location names to avoid any potential errors caused by inconsistent use of punctuation.
4. Removing unnecessary words: Some location names contain unnecessary words such as "the," "city," or "town." These words were removed to simplify the location names and improve accuracy.
5. Standardizing abbreviations: Abbreviations were standardized to ensure consistency. For example, "St." was changed to "Street," and "Ave." was changed to "Avenue."
6. Expanding contractions: Contractions were expanded to their full form to ensure consistency. For example, "don't" was changed to "do not."
By normalizing the data, we were able to ensure consistency and accuracy in the location names, which is crucial for natural language processing tasks such as geocoding and entity recognition.
