PyTorch, a model is represented by a regular Python class that inherits from the Module class. • Two components • __init__(self): it defines the parts that make up the model —in our case, two parameters, a kind of a Python list of tuples, each tuple corresponding to one point (features, label) • 3 components: • __init__(self) • __get_item__(self, index) • __len__(self) • Unless the dataset is huge

decomposition 模块包含了一系列无监督降维算法 from sklearn.decomposition import PCA 导入PCA库，设置主成分数量为3，n_components代表主成分数量 pca = PCA(n_components=3) 训练模型 pca.fit(X) 投影后各个特征维度的方差比例(这里是三个主成分) print(pca.explained_variance_ratio_)

human designed models. However, the key contribution of NASNet was the focus on predicting the components of child networks which enabled the construction of multiscale networks without needing to tweak ), dict(name='combinations', values=['add', 'concat'], count=1), ] The STATE_SPACE has three components to mimic the NASNet search space. The hidden_state element can take two values to represent the

compression, and the MP3 format for audio. DCT breaks down the given input data into independent components of which the ones that don’t contribute much to the original input can be discarded, based on the graph using the create_model() function. Then, it compiles the model by providing the necessary components the framework needs to train the model. This includes the loss function, the optimizer, and finally
