Accelerating the pace of engineering and science. Any ideas to improve the network accuracy, like adjusting learnable parameters or net structures? Why did the L1/L2 regularization technique not improve my accuracy? 2.) You're right, sometimes the routine augmentations do not add additional value. In other words, the test (or testing) accuracy often refers to the validation accuracy, that is, the accuracy you calculate on the data set you do not use for training, but you use (during the training process) for validating (or "testing") the generalisation ability of your model or for "early stopping". So with little data, training accuracy don't really have time to converge to 100% accuracy. Are you shuffling your data enough and randomly putting samples in both the training and test sets? A Medium publication sharing concepts, ideas and codes. Here are some ways of how Machine Learning can help with data entry accuracy: 1. Tried ImageDataGenerator but still it's of no use.

After making changes in the model as above, you will probably see the stabilization of the accuracy in some range. Is MATLAB command "fourier" only applicable for continous-time signals or is it also applicable for discrete-time signals? Finally I got random results, with a 33% accuracy ! Found footage movie where teens get superpowers after getting struck by lightning? Mid-iron Distance Control: Not knowing the distance for my normal 7-, 8-, and 9-irons shots resulted in a number of extremely difficult recovery situations that led to a third of my bogeys. The unwanted presence of missing and outlier values in the training data often reduces a model's accuracy or leads to a biased model. Shift+walking while shooting decreases accuracy by a very slight amount. Instead of training the model over and over again, why not select the images the model incorrectly labeled and train the model specifically on these images? Also, it reduced the number of training parameters down to less than half of the previous model. Further study is needed to verify this assumption. Only 1 hidden layer may not be sufficient for the training of your data. Random Forest works very well on both the categorical ( Random Forest Classifier) as well as continuous Variables (Random Forest Regressor). I think I simplified enough the architecture / applied enough dropout, because my network is even too dumb to learn anything and return random results (3-classes classifier => 33% is random accuracy), even on training dataset : My question is : This accuracy of 70% is the best my model can reach ? What bugged me at that moment is that no matter what kind of model I used, how deep or how complex, always the accuracy was fine, stabilized at some nice level. Check out this article to read more about different face detection algorithms! 2. The dataset consists of 3522 images belonging to 2 class of training and 881 images belonging to 2 classes of test set. 4.4.

Make sure that you train/test sets come from the same distribution 3. Use it to build a quick benchmark of the model as it is fast to train. It's fine with your regularization code, but now you have to change the value of these regularizations, and look for "the best value". Validation accuracy is same throughout the training. Other than that, however, the model could pretty accurately recognize the emotions I was making, even when my face was partially obscured (thanks to the wide variety of images in the dataset). I am using Xception as the pretrained model and combined with GlobalAveragePooling2D, a dense layer and dropout of 0.2. Reload the page to see its updated state. 54%! It allows the "data to tell for itself," instead of relying on assumptions and weak correlations. Employees cannot provide accurate work if they don't understand what is expected. If you have "n" sources of data, you need to make sure that your training set has many samples from each of the "n" sources of data and your test set has samples from each of the "n" sources.
