• implement evaluation measures used in LinkNet and modify evaluation.py so that it makes use of numpy/scipy
• evaluate our LinkNet
• implement inference time measurement depending on mini-batch size (to compare with the results in the LinkNet paper)
• write the report

• nothing

• use tf.nn.sparse_softmax_cross_entropy_with_logits for more efficient training
• make a baseline similar to BaselineA that uses strided convolutions instead of pooling layers (use 3x3 conv with stride 2 instead of pool->conv)
• try IoU loss (like here)

• finish saving and loading of trained models ~ Ivan
• implement LinkNet ~ Josip

• make data loading work (data.preparers.Iccv09Preparer, data.Dataset)
• make a simple baseline
• complete abstract_model
• make the cost function (as well as other used evaluation measures) in BaselineA ignore "unknown" class (class 0)
• implement util.Visualizer
• improve the colors in util.visualizer.Visualizer
• enable usage of util.Visualizer while training (by pressing d followed by ENTER in the console)
• add stride:int and dilation:int parameters to tf_utils.layers.conv (use tf.nn.convolution)
• add batch normalization to tf_utils.layers, use tf.layers.batch_normalization(input_layer, fused=True, data_format='NCHW')
• improve random seeding in Dataset for beter reproducibility
• add ResNet layers and encoder/decoder blocks used in LinkNet to tf_utils.blocks
• implement a textual options menu that can be opened while training is paused, enabling network output visualization, saving/loading of weights, stopping training (after the current epoch) and other actions
• add transposed convolution to tf_utils.layers

"Inference time" - on what hardware?
