Use with care.\n\n This implementation follows the paper:\n Lacoste-Julien, Jaggi, Schmidt, Pletscher JMLR 2013\n Block-Coordinage Frank-Wolfe Optimization for Structural SVMs\n\n With batch_mode=False, this implements the online (block-coordinate)\n version of the algorithm (BCFW)\n BCFW is an attractive alternative to subgradient methods, as no\n learning rate is needed and a duality gap guarantee is given.\n\n Parameters\n ----------\n model : StructuredModel\n Object containing the model structure. Has to implement\n `loss`, `inference` and `loss_augmented_inference`.\n\n max_iter : int, default=1000\n Maximum number of passes over dataset to find constraints.\n\n C : float, default=1\n Regularization parameter. Corresponds to 1 / (lambda * n_samples).\n\n verbose : int\n Verbosity.\n\n n_jobs : int, default=1\n Number of parallel processes. Currently only n_jobs=1 is supported.\n\n show_loss_every : int, default=0\n How often the training set loss should be computed.\n Zero corresponds to never.\n\n tol : float, default=1e-3\n Convergence tolerance on the duality gap.\n\n logger : logger object, default=None\n Pystruct logger for storing the model or extracting additional\n information.\n\n batch_mode : boolean, default=False\n Whether to use batch updates. Will slow down learning enormously.\n\n line_search : boolean, default=True\n Whether to compute the optimum step size in each step.\n The line-search is done in closed form and cheap.\n There is usually no reason to turn this off.\n\n check_dual_every : int, default=10\n How often the stopping criterion should be checked. Computing\n the stopping criterion is as costly as doing one pass over the dataset,\n so check_dual_every=1 will make learning twice as slow.\n\n do_averaging : bool, default=True\n Whether to use weight averaging as described in the reference paper.\n Currently this is only supported in the block-coordinate version.\n\n random_state : int, RandomState instance or None, optional (default=None)\n If int, random_state is the seed used by the random number generator;\n If RandomState instance, random_state is the random number generator;\n If None, the random number generator is the RandomState instance used\n by `np.random`.\n\n\n Attributes\n ----------\n w : nd-array, shape=(model.size_psi,)\n The learned weights of the SVM.\n\n ``loss_curve_`` : list of float\n List of loss values if show_loss_every > 0.\n\n ``objective_curve_`` : list of float\n Cutting plane objective after each pass through the dataset.\n\n ``primal_objective_curve_`` : list of float\n Primal objective after each pass through the dataset.\n\n ``timestamps_`` : list of int\n Total training time stored before each iteration.\n \"\"\"\n def __init__(self, model, max_iter=1000, C=1.0, verbose=0, n_jobs=1,\n show_loss_every=0, logger=None, batch_mode=False,\n line_search=True, check_dual_every=10, tol=.001,\n do_averaging=True, sample_method='perm', random_state=None):\n\n if n_jobs != 1:\n warnings.warn(\"FrankWolfeSSVM does not support multiprocessing\"\n \" yet.

However, one can experiment with variations of the inception_v3\r\n network by changing arguments dropout_keep_prob, min_depth and\r\n depth_multiplier.\r\n\r\n The default image size used to train this network is 299x299.\r\n\r\n Args:\r\n inputs: a tensor of size [batch_size, height, width, channels].\r\n num_classes: number of predicted classes. If 0 or None, the logits layer\r\n is omitted and the input features to the logits layer (before dropout)\r\n are returned instead.\r\n is_training: whether is training or not.\r\n dropout_keep_prob: the percentage of activation values that are retained.\r\n min_depth: Minimum depth value (number of channels) for all convolution ops.\r\n Enforced when depth_multiplier < 1, and not an active constraint when\r\n depth_multiplier >= 1.\r\n depth_multiplier: Float multiplier for the depth (number of channels)\r\n for all convolution ops. The value must be greater than zero. Typical\r\n usage will be to set this value in (0, 1) to reduce the number of\r\n parameters or computation cost of the model.\r\n prediction_fn: a function to get predictions out of logits.\r\n spatial_squeeze: if True, logits is of shape [B, C], if false logits is of\r\n shape [B, 1, 1, C], where B is batch_size and C is number of classes.\r\n reuse: whether or not the network and its variables should be reused. To be\r\n able to reuse 'scope' must be given.\r\n create_aux_logits: Whether to create the auxiliary logits.\r\n scope: Optional variable_scope.\r\n global_pool: Optional boolean flag to control the avgpooling before the\r\n logits layer. If false or unset, pooling is done with a fixed window\r\n that reduces default-sized inputs to 1x1, while larger inputs lead to\r\n larger outputs. If true, any input size is pooled down to 1x1.\r\n\r\n Returns:\r\n net: a Tensor with the logits (pre-softmax activations) if num_classes\r\n is a non-zero integer, or the non-dropped-out input to the logits layer\r\n if num_classes is 0 or None.\r\n end_points: a dictionary from components of the network to the corresponding\r\n activation.\r\n\r\n Raises:\r\n ValueError: if 'depth_multiplier' is less than or equal to zero.\r\n \"\"\"\r\n if depth_multiplier <= 0:\r\n raise ValueError('depth_multiplier is not greater than zero.')\r\n depth = lambda d: max(int(d * depth_multiplier), min_depth)\r\n\r\n with tf.variable_scope(scope, 'InceptionV3', [inputs], reuse=reuse) as scope:\r\n with slim.arg_scope([slim.batch_norm, slim.dropout],\r\n is_training=is_training):\r\n net, end_points = inception_v3_base(\r\n inputs, scope=scope, min_depth=min_depth,\r\n depth_multiplier=depth_multiplier)\r\n\r\n # Auxiliary Head logits\r\n if create_aux_logits and num_classes:\r\n with slim.arg_scope([slim.conv2d, slim.max_pool2d, slim.avg_pool2d],\r\n stride=1, padding='SAME'):\r\n aux_logits = end_points['Mixed_6e']\r\n with tf.variable_scope('AuxLogits'):\r\n aux_logits = slim.avg_pool2d(\r\n aux_logits, [5, 5], stride=3, padding='VALID',\r\n scope='AvgPool_1a_5x5')\r\n aux_logits = slim.conv2d(aux_logits, depth(128), [1, 1],\r\n scope='Conv2d_1b_1x1')\r\n\r\n # Shape of feature map before the final layer.\r\n kernel_size = _reduced_kernel_size_for_small_input(\r\n aux_logits, [5, 5])\r\n aux_logits = slim.conv2d(\r\n aux_logits, depth(768), kernel_size,\r\n weights_initializer=trunc_normal(0.01),\r\n padding='VALID', scope='Conv2d_2a_{}x{}'.format(*kernel_size))\r\n aux_logits = slim.conv2d(\r\n aux_logits, num_classes, [1, 1], activation_fn=None,\r\n normalizer_fn=None, weights_initializer=trunc_normal(0.001),\r\n scope='Conv2d_2b_1x1')\r\n if spatial_squeeze:\r\n aux_logits = tf.squeeze(aux_logits, [1, 2], name='SpatialSqueeze')\r\n end_points['AuxLogits'] = aux_logits\r\n\r\n # Final pooling and prediction\r\n with tf.variable_scope('Logits'):\r\n if global_pool:\r\n # Global average pooling.\r\n net = tf.reduce_mean(net, [1, 2], keep_dims=True, name='GlobalPool')\r\n end_points['global_pool'] = net\r\n else:\r\n # Pooling with a fixed kernel size.\r\n kernel_size = _reduced_kernel_size_for_small_input(net, [8, 8])\r\n net = slim.avg_pool2d(net, kernel_size, padding='VALID',\r\n scope='AvgPool_1a_{}x{}'.format(*kernel_size))\r\n end_points['AvgPool_1a'] = net\r\n if not num_classes:\r\n return net, end_points\r\n # 1 x 1 x 2048\r\n net = slim.dropout(net, keep_prob=dropout_keep_prob, scope='Dropout_1b')\r\n end_points['PreLogits'] = net\r\n # 2048\r\n logits = slim.conv2d(net, num_classes, [1, 1], activation_fn=None,\r\n normalizer_fn=None, scope='Conv2d_1c_1x1')\r\n if spatial_squeeze:\r\n logits = tf.squeeze(logits, [1, 2], name='SpatialSqueeze')\r\n # 1000\r\n end_points['Logits'] = logits\r\n end_points['Predictions'] = prediction_fn(logits, scope='Predictions')\r\n return logits, end_points\r\ninception_v3.default_image_size = 299\r\n\r\n\r\ndef _reduced_kernel_size_for_small_input(input_tensor, kernel_size):\r\n \"\"\"Define kernel size which is automatically reduced for small input.\r\n\r\n If the shape of the input images is unknown at graph construction time this\r\n function assumes that the input images are is large enough.\r\n\r\n Args:\r\n input_tensor: input tensor of size [batch_size, height, width, channels].\r\n kernel_size: desired kernel size of length 2: [kernel_height, kernel_width]\r\n\r\n Returns:\r\n a tensor with the kernel size.\r\n\r\n TODO(jrru): Make this function work with unknown shapes.

It involves *computation*, defined\n in the `call()` method, and a *state* (weight variables), defined\n either in the constructor `__init__()` or in the `build()` method.\n\n Users will just instantiate a layer and then treat it as a callable.\n\n Arguments:\n trainable: Boolean, whether the layer's variables should be trainable.\n name: String name of the layer.\n dtype: The dtype of the layer's computations and weights (default of\n `None` means use `tf.keras.backend.floatx` in TensorFlow 2, or the type\n of the first input in TensorFlow 1).\n dynamic: Set this to `True` if your layer should only be run eagerly, and\n should not be used to generate a static computation graph.\n This would be the case for a Tree-RNN or a recursive network,\n for example, or generally for any layer that manipulates tensors\n using Python control flow. If `False`, we assume that the layer can\n safely be used to generate a static computation graph.\n\n Attributes:\n name: The name of the layer (string).\n dtype: The dtype of the layer's computations and weights. If mixed\n precision is used with a `tf.keras.mixed_precision.experimental.Policy`,\n this is instead just the dtype of the layer's weights, as the computations\n are done in a different dtype.\n trainable_weights: List of variables to be included in backprop.\n non_trainable_weights: List of variables that should not be\n included in backprop.\n weights: The concatenation of the lists trainable_weights and\n non_trainable_weights (in this order).\n trainable: Whether the layer should be trained (boolean), i.e. whether\n its potentially-trainable weights should be returned as part of\n `layer.trainable_weights`.\n input_spec: Optional (list of) `InputSpec` object(s) specifying the\n constraints on inputs that can be accepted by the layer.\n\n We recommend that descendants of `Layer` implement the following methods:\n\n * `__init__()`: Defines custom layer attributes, and creates layer state\n variables that do not depend on input shapes, using `add_weight()`.\n * `build(self, input_shape)`: This method can be used to create weights that\n depend on the shape(s) of the input(s), using `add_weight()`. `__call__()`\n will automatically build the layer (if it has not been built yet) by\n calling `build()`.\n * `call(self, *args, **kwargs)`: Called in `__call__` after making sure\n `build()` has been called. `call()` performs the logic of applying the\n layer to the input tensors (which should be passed in as argument).\n Two reserved keyword arguments you can optionally use in `call()` are:\n - `training` (boolean, whether the call is in\n inference mode or training mode)\n - `mask` (boolean tensor encoding masked timesteps in the input, used\n in RNN layers)\n * `get_config(self)`: Returns a dictionary containing the configuration used\n to initialize this layer. If the keys differ from the arguments\n in `__init__`, then override `from_config(self)` as well.\n This method is used when saving\n the layer or a model that contains this layer.\n\n Examples:\n\n Here's a basic example: a layer with two variables, `w` and `b`,\n that returns `y = w . x + b`.\n It shows how to implement `build()` and `call()`.\n Variables set as attributes of a layer are tracked as weights\n of the layers (in `layer.weights`).\n\n ```python\n class SimpleDense(Layer):\n\n def __init__(self, units=32):\n super(SimpleDense, self).__init__()\n self.units = units\n\n def build(self, input_shape): # Create the state of the layer (weights)\n w_init = tf.random_normal_initializer()\n self.w = tf.Variable(\n initial_value=w_init(shape=(input_shape[-1], self.units),\n dtype='float32'),\n trainable=True)\n b_init = tf.zeros_initializer()\n self.b = tf.Variable(\n initial_value=b_init(shape=(self.units,), dtype='float32'),\n trainable=True)\n\n def call(self, inputs): # Defines the computation from inputs to outputs\n return tf.matmul(inputs, self.w) + self.b\n\n # Instantiates the layer.\n linear_layer = SimpleDense(4)\n\n # This will also call `build(input_shape)` and create the weights.\n y = linear_layer(tf.ones((2, 2)))\n assert len(linear_layer.weights) == 2\n\n # These weights are trainable, so they're listed in `trainable_weights`:\n assert len(linear_layer.trainable_weights) == 2\n ```\n\n Note that the method `add_weight()` offers a shortcut to create weights:\n\n ```python\n class SimpleDense(Layer):\n\n def __init__(self, units=32):\n super(SimpleDense, self).__init__()\n self.units = units\n\n def build(self, input_shape):\n self.w = self.add_weight(shape=(input_shape[-1], self.units),\n initializer='random_normal',\n trainable=True)\n self.b = self.add_weight(shape=(self.units,),\n initializer='random_normal',\n trainable=True)\n\n def call(self, inputs):\n return tf.matmul(inputs, self.w) + self.b\n ```\n\n Besides trainable weights, updated via backpropagation during training,\n layers can also have non-trainable weights. These weights are meant to\n be updated manually during `call()`. Here's a example layer that computes\n the running sum of its inputs:\n\n ```python\n class ComputeSum(Layer):\n\n def __init__(self, input_dim):\n super(ComputeSum, self).__init__()\n # Create a non-trainable weight.\n self.total = tf.Variable(initial_value=tf.zeros((input_dim,)),\n trainable=False)\n\n def call(self, inputs):\n self.total.assign_add(tf.reduce_sum(inputs, axis=0))\n return self.total\n\n my_sum = ComputeSum(2)\n x = tf.ones((2, 2))\n\n y = my_sum(x)\n print(y.numpy()) # [2. 2.]\n\n y = my_sum(x)\n print(y.numpy()) # [4. 4.]\n\n assert my_sum.weights == [my_sum.total]\n assert my_sum.non_trainable_weights == [my_sum.total]\n assert my_sum.trainable_weights == []\n ```\n\n For more information about creating layers, see the guide\n [Writing custom layers and models with Keras](\n https://www.tensorflow.org/guide/keras/custom_layers_and_models)\n\n About the layer's `dtype` attribute:\n\n Each layer has a dtype, which is typically the dtype of the layer's\n computations and variables. A layer's dtype can be queried via the\n `Layer.dtype` property. The dtype is specified with the `dtype` constructor\n argument. In TensorFlow 2, the dtype defaults to `tf.keras.backend.floatx()`\n if no dtype is passed. `floatx()` itself defaults to \"float32\". Additionally,\n layers will cast their inputs to the layer's dtype in TensorFlow 2. When mixed\n precision is used, layers may have different computation and variable dtypes.\n See `tf.keras.mixed_precision.experimental.Policy` for details on layer\n dtypes.\n \"\"\"\n\n # See tf.Module for the usage of this property.\n # The key for _obj_reference_counts_dict is a Trackable, which could be a\n # variable or layer etc. tf.Module._flatten will fail to flatten the key\n # since it is trying to convert Trackable to a string. This attribute can be\n # ignored even after the fix of nest lib, since the trackable object should\n # already been available as individual attributes. _obj_reference_counts_dict\n # just contains a copy of them.\n _TF_MODULE_IGNORED_PROPERTIES = frozenset(itertools.chain(\n ('_obj_reference_counts_dict',),\n module.Module._TF_MODULE_IGNORED_PROPERTIES\n ))\n\n # When loading from a SavedModel, Layers typically can be revived into a\n # generic Layer wrapper. Sometimes, however, layers may implement methods\n # that go beyond this wrapper, as in the case of PreprocessingLayers'\n # `adapt` method. When this is the case, layer implementers can override\n # must_restore_from_config to return True; layers with this property must\n # be restored into their actual objects (and will fail if the object is\n # not available to the restoration code).\n _must_restore_from_config = False\n\n @trackable.no_automatic_dependency_tracking\n def __init__(self,\n trainable=True,\n name=None,\n dtype=None,\n dynamic=False,\n **kwargs):\n # These properties should be set by the user via keyword arguments.\n # note that 'dtype', 'input_shape' and 'batch_input_shape'\n # are only applicable to input layers: do not pass these keywords\n # to non-input layers.\n allowed_kwargs = {\n 'input_dim',\n 'input_shape',\n 'batch_input_shape',\n 'batch_size',\n 'weights',\n 'activity_regularizer',\n 'autocast',\n }\n # Validate optional keyword arguments.\n generic_utils.validate_kwargs(kwargs, allowed_kwargs)\n\n # Mutable properties\n # Indicates whether the layer's weights are updated during training\n # and whether the layer's updates are run during training.\n self._trainable = trainable\n # A stateful layer is a layer whose updates are run during inference too,\n # for instance stateful RNNs.\n self._stateful = False\n # Indicates whether `build` needs to be called upon layer call, to create\n # the layer's weights.\n self.built = False\n # Record the build input shape for loading purposes.\n # TODO(kathywu): Move this to Layer._set_save_spec once cl/290121460 is\n # submitted.\n self._build_input_shape = None\n self._saved_model_inputs_spec = None\n # Provides information about which inputs are compatible with the layer.\n self._input_spec = None\n\n # `Layer.compute_mask` will be called at the end of `Layer.__call__` if\n # `Layer.compute_mask` is overridden, or if the `Layer` subclass sets\n # `self.supports_masking=True`.\n self._supports_masking = not generic_utils.is_default(self.compute_mask)\n\n self._init_set_name(name)\n self._activity_regularizer = regularizers.get(\n kwargs.pop('activity_regularizer', None))\n self._maybe_create_attribute('_trainable_weights', [])\n self._maybe_create_attribute('_non_trainable_weights', [])\n self._updates = []\n # Object to store all thread local layer properties.\n self._thread_local = threading.local()\n # A list of zero-argument lambdas which return Tensors, used for variable\n # regularizers.\n self._callable_losses = []\n # A list of symbolic Tensors containing activity regularizers and losses\n # manually added through `add_loss` in graph-building mode.\n self._losses = []\n # A list of metric instances corresponding to the symbolic metric tensors\n # added using the `add_metric` API.\n self._metrics = []\n # Ensures the same metric is not added multiple times in `MirroredStrategy`.\n self._metrics_lock = threading.Lock()\n\n # Both graph and subclassed networks have a dtype policy.
