Python 实现将句子序列转换为词向量序列

def sentences_to_indices(X, word_to_index, dim, max_len, E): m = X.shape[0] # 句子数量 X_indices = np.zeros((m, max_len, dim))

for i in range(m):
    sentence_words = X[i].lower().split()
    j = 0
    for word in sentence_words:
        if j >= max_len:
            break
        if word in word_to_index:
            X_indices[i, j, :] = E[word_to_index[word]]
        j += 1

return X_indices
