loss decreasing accuracy not increasing pytorch

And no matter what loss the training starts at, it always comes at this value. Your training and testing data should be different, for the reason that it is easy to overfit the training data, but the true goal is for the algorithm to perform on data it has not seen before. It is taking around 10 to 15 epochs to reach 60% accuracy. The model is updating weights but loss is constant. 0.564388 Train Epoch: 8 [200/249 (80%)] Loss: 0.517878 Test set: Average loss: 0.4522, Accuracy: 37/63 (58%) Train Epoch: 9 [0/249 Validation accuracy is increasing but the WER has converged after around 9-10 epochs. Learning rate is 0.01. When the migration is complete, you will access your Teams at stackoverflowteams.com, and they will no longer appear in the left sidebar on stackoverflow.com. Whats the accuracy of PyTorch in 9th epoch? That are the common values that must work against this behavior. Learning rate is 0.01. Therefore, batch_size should be treated as a hyperparameter. It only takes a minute to sign up. That being said, there are some general guidelines which often work for me. Stack Exchange network consists of 182 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. The return_sequences parameter is set to true for returning the last output in output . Transfer Learning - Val_loss strange behaviour, constant loss values with normal CNNs and transfer learning, Make a wide rectangle out of T-Pipes without loops. If you have already tried to change the learning rate try to change training algorithm. i am trying to create 3d CNN using pytorch. But accuracy doesn't improve and stuck. Would it be illegal for me to act as a Civillian Traffic Enforcer?

It's up to the practitioner to scout for how to implement all this stuff. input image: 120 * 120 * 120 Is a planet-sized magnet a good interstellar weapon? By clicking Sign up for GitHub, you agree to our terms of service and It is not even overfitting on only three training examples I have used other loss functions as well like dice+binarycrossentropy loss, jacard loss and MSE loss but the loss is almost constant. eqy (Eqy) May 23, 2021, 4:34am #11 Ok, that sounds normal. How to create a bceloss class in PyTorch? Also, the newCorrect in your validation loop does not compare with target values. Why does the loss/accuracy fluctuate during the training? But, here are the things I'd do: 1) As you're dealing with images, try to pre-process them a bit ( rotation, normalization, Gaussian Noise etc). Looking at your code, I see two possible sources. But I still got the same problem: loss was fluctuating instead of just decreasing. The robot has many sensors but I only use the measurements of current. 1 Why is the loss function not decreasing in PyTorch? In this example, neither the training loss nor the validation loss decrease. What is the effect of cycling on weight loss? Data Preprocessing: Standardizing and Normalizing the data. So I think that you're doing something fishy. Found footage movie where teens get superpowers after getting struck by lightning? Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. [0/249 (0%)] Loss: 0.481739 Train Epoch: 8 [100/249 (40%)] Loss: I know it is crazy. How do I make kelp elevator without drowning? To subscribe to this RSS feed, copy and paste this URL into your RSS reader. The main one though is the fact that almost all neural nets are trained with different forms of stochastic gradient descent. Batch size will also play into how your network learns, so you might want to optimize that along with your learning rate. But accuracy doesn't improve and stuck. MathJax reference. class torch.nn.BCELoss(weight=None, size_average=None, reduce=None, reduction=mean) [source] Creates a criterion that measures the Binary Cross Entropy between the target and the output: The unreduced (i.e. What is the difference between these differential amplifier circuits? If you continue to use this site we will assume that you are happy with it. batch-training LSTM with pretrained & out-of-vocabulary word embeddings in keras, Difference between batch_size=1 and SGD optimisers in Keras, Tensorflow loss and accuracy during training weird values. next step on music theory as a guitar player. The model is overfitting right from epoch 10, the validation loss is increasing while the training loss is decreasing. If model weights and data are of very different magnitude it can cause no or very low learning progression, and in the extreme case lead to numerical instability. You are right. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. So in your case, your accuracy was 37/63 in 9th epoch. I have tried different values for lr but still got the same result. Moreover, I have tried different learning rates as well like 0.0001, 0.001, 0.1. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Pytorch - Loss is decreasing but Accuracy not improving, Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned, Loss for CNN decreases and settles but training accuracy does not improve. preds = torch.max (output, dim=1, keepdim=True) [1] This looks very odd. 7 Why does PyTorch have no learning progression? To learn more, see our tips on writing great answers. Finally, I've personally never had much success training with dice as the primary loss function, so I would definitely try to get it working with cross entropy first, and then move on to dice. I use LSTM network in Keras. It sounds like you trained it for 800 epochs and are only showing the first 50 epochs - the whole curve will likely give a very different story. If a creature would die from an equipment unattaching, does that creature die with the effects of the equipment? Having it too large would also make training go slow. 4) Add a learning rate scheduler to your optimizer, to change learning rates if there's no improvement over time. @MuhammadHamzaMughal since you are using sigmoid to generate predictions, have you made sure that the target attributes in ground truth/training data/validation data are all in range [0-1] ? We use cookies to ensure that we give you the best experience on our website. It is important that you always check the range of the input data.

Thanks in advance! A small contrived example of an underfit LSTM model is provided below. I have always thought that the loss is just suppose to gradually go down but here it does not seem to behave like that. It seems loss is decreasing and the algorithm works fine. When using BCEWithLogitsLoss for binary classification, the output of your network would have a single value try 1e-5 or zero first you cann't use batch size 1 in train, if you are using batchnorm layer. Add dropout, reduce number of layers or number of neurons in each layer. 3 How to change learning rate in PyTorch stack? You would agree to test your data: first compute the Bayes error rate using a KNN (use the trick regression in case you need), in this way you can check whether the input data contain all the information you need. A fast learning rate means you descend down quickly because you likely are far away from any minimum. I'am beginner in deep learning, I created 3DCNN using Pytorch. To put this into perspective, you want to learn 200K parameters or find a good local minimum in a 200K-D space using only 100 samples. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. It is not even overfitting on only three training examples, I have used other loss functions as well like dice+binarycrossentropy loss, jacard loss and MSE loss but the loss is almost constant. When the batch_size is larger, such effects would be reduced. Are Githyanki under Nondetection all the time? Thanks. How can underfit LSTM model be diagnosed from a plot? the problem that the accuracy and loss are increasing and decreasing (accuracy values are between 37% 60%) NOTE: if I delete dropout layer the accuracy and loss values remain unchanged for all epochs Do you know what I am doing wrong here? It seems loss is decreasing and the algorithm works fine. How can i extract files in the directory where they're located with the find command? You can learn a lot about the behavior of your model by reviewing its performance over time. Some images with very bad predictions keep getting worse (eg a cat image whose prediction was 0.2 becomes 0.1). Is it normal for the loss to fluctuate like that during the training? Find centralized, trusted content and collaborate around the technologies you use most. changed the sampling frequency so the sequences are not too long (LSTM does not seem to learn otherwise); cut the sequences in the smaller sequences (the same length for all of the smaller sequences: 100 timesteps each); check that each of 6 classes has approximately the same number of examples in the training set. Connect and share knowledge within a single location that is structured and easy to search. (Please, note that I have checked similar questions here but it did not help me to resolve my issue.). Hope this helps. When the loss decreases but accuracy stays the same, you probably better predict the images you already predicted. What is the effect of cycling on weight loss? Test set: Average loss: 0.5094, Accuracy: 37/63 (58%) Train Epoch: 8 (The wandering is also due to the second reason below). This wrapper pulls out that output , and adds a get_output_dim method, which is useful if you want to, e.g., define a linear + softmax layer on top of . Can an autistic person with difficulty making eye contact survive in the workplace? During the training, the loss fluctuates a lot, and I do not understand why that would happen. From the graphs you have posted, the problem depends on your data so it's a difficult training. Using friction pegs with standard classical guitar headstock, Replacing outdoor electrical box at end of conduit. The best answers are voted up and rise to the top, Not the answer you're looking for? The text was updated successfully, but these errors were encountered: Please use discuss.pytorch.org for questions. (0%)] Loss: 0.420650 Train Epoch: 9 [100/249 (40%)] Loss: 0.521278 Its normal to see your training performance continue to improve even though your test data performance has converged. If not, why would this happen for the simple LSTM model with the lr parameter set to some really small value? Making statements based on opinion; back them up with references or personal experience. You got to add code of at least your forward and train functions for us to pinpoint the issue, @Jatentaki is right there could be so many things that could mess up a ML / DL code. What value for LANG should I use for "sort -u correctly handle Chinese characters? Who knows, maybe. When calculating loss, however, you also take into account how well your model is predicting the correctly predicted images. Do you know what I am doing wrong here? When calculating loss, however, you also take into account how well your model is predicting the correctly predicted images. : loss for 1000+ epochs (no BatchNormalization layer, Keras' unmodifier RmsProp): Data: sequences of values of the current (from the sensors of a robot). And here are the loss&accuracy during the training: (Note that the accuracy actually does reach 100% eventually, but it takes around 800 epochs.). I don't think (in normal usage) that you can get a loss that low with BCEWithLogitsLoss when your accuracy is 50%. Water leaving the house when water cut off. If your batch size is constant, this can't explain your loss issue. You use very small batch_size. This increase in loss value is due to Adam, the moment the local minimum is exceeded and a certain number of iterations, a small number is divided by an even smaller number and the loss value explodes. Could you post some more information regarding your experiment? You should move it validation step only. The huge spikes you get at about 1200 epochs remind me of a case where I had to deal exactly with that. Is cycling an aerobic or anaerobic exercise? (40%)] Loss: 0.597774 Train Epoch: 7 [200/249 (80%)] Loss: 0.554897 5 What is the accuracy of Python-PyTorch-loss? How to help a successful high schooler who is failing in college? Code: import numpy as np import cv2 from os import listdir from os.path import isfile, join from sklearn.utils import shuffle import torch.nn as nn import torch.nn.functional as F import torch.optim as optim from torch.autograd import Variable Why is the loss function not decreasing in PyTorch? Making statements based on opinion; back them up with references or personal experience. When calculating loss, however, you also take into account how well your model is predicting the correctly predicted images. 3 Keras LSTM Layer Example with Stock Price Prediction. I have updated the post with the training for 1000+ epochs. I'am beginner in deep learning, I created 3DCNN using Pytorch. So it's like you are trusting every small portion of the data points. 1. Cross Validated is a question and answer site for people interested in statistics, machine learning, data analysis, data mining, and data visualization. note: if I delete dropout layer the accuracy and loss values remain unchanged for all epochs Why do I get two different answers for the current through the 47 k resistor when I do a source transformation? Fluctuating loss curve/ steady dice score. Along with other reasons, it's good to have batch_size higher than some minimum. The accuracy just shows how much you got right out of your samples. But accuracy doesn't improve and stuck. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Sign in Leveraging trained parameters, even if only a few are usable, will help to warmstart the training process and hopefully help your model converge much faster than training from scratch. Target variables: the surface on which robot is operating (as a one-hot vector, 6 different categories). XGBoosted_Learner: batch_size = 1 you should try simpler optim method like SGD first,try it with lr .05 and mumentum .9 The problem is that for a very simple test sample case, the loss function is not decreasing. 0.3944, Accuracy: 37/63 (58%). It should definitely "fluctuate" up and down a bit, as long as the general trend is that it is going down - this makes sense. Partially loading a model or loading a partial model are common scenarios when transfer learning or training a new complex model. Statistical learning theory is not a topic that can be talked about at one time, we must proceed step by step. Such a difference in Loss and Accuracy happens. What degree of difference does validation and training loss need to have to be called overfit? For the LSTM layer, we add 50 units that represent the dimensionality of outer space. I have also tried almost every activation function like ReLU, LeakyReLU, Tanh. Consider label 1, predictions 0.2, 0.4 and 0.6 at timesteps 1, 2, 3 and classification threshold 0.5. timesteps 1 and 2 will produce a decrease in loss but no increase in accuracy. Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. And overall loss. Logically, the training and validation loss should decrease and then saturate which is happening but also, it should give 100% or a very large accuracy on the valid set ( As it is same as of training set), but it is giving 0% accuracy. Non-anthropic, universal units of time for active SETI, Make a wide rectangle out of T-Pipes without loops. Does the Fog Cloud spell work in conjunction with the Blind Fighting fighting style the way I think it does? 4 Is the model suffering from overfitting in machine learning? And why it would happen? Say you have some complex surface with countless peaks and valleys. 4) Add a learning rate scheduler to your optimizer, to change learning rates if theres no improvement over time. It's not really a question for stack overflow. More importantly, x = torch.round (x) is redundant for BCELoss. communities including Stack Overflow, the largest, most trusted online community for developers learn, share their knowledge, and build their careers. How do you know the performance of a LSTM model? Freundlicher Here is the NN I was using initially: And here are the loss&accuracy during the training: (Note that the accuracy actually does reach 100% eventually, but it takes around 800 epochs.) File ended while scanning use of \verbatim@start", Horror story: only people who smoke could see some monsters. What value for LANG should I use for "sort -u correctly handle Chinese characters? Why does the sentence uses a question form, but it is put a period in the end? You signed in with another tab or window. The loss looks indeed a bit fishy. By default, False. The accuracy just shows how much you got right out of your samples. 1 Answer Sorted by: 0 x = torch.round (x) prevents you from updating your model because it's non-differentiable. weight_decay = 0.1 this is too high. Besides, after I re-run the training, it is even less stable than it was, so I am almost sure I am missing some error. This is the classic " loss decreases while accuracy increases " behavior that we expect. The fluctuations are normal within certain limits and depend on the fact that you use a heuristic method but in your case they are excessive. It's pretty normal. Moreover, I have tried different learning rates as well like 0.0001, 0.001, 0.1. For batch_size=2 the LSTM did not seem to learn properly (loss fluctuates around the same value and does not decrease). Despite all the performance takes a definite direction and therefore the system works. This is why batch_size parameter exists which determines how many samples you want to use to make one update to the model parameters. Model compelxity: Check if the model is too complex. How do I print the model summary in PyTorch? What is the best way to show results of a multiple-choice quiz where multiple options may be right? To learn more, see our tips on writing great answers. Did Dick Cheney run a death squad that killed Benazir Bhutto? Can "it's down to him to fix the machine" and "it's up to him to fix the machine"? By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Stack Overflow for Teams is moving to its own domain! 2 What is LSTM ? Cat Dog classifier in tensorflow, fundamental problem! You don't have to divide the loss by the batch size, since your criterion does compute an average of the batch loss. We just want the final hidden state of the last time step. import numpy as np import cv2 from os import listdir from os.path import isfile, join from sklearn.utils import shuffle. privacy statement. tcolorbox newtcblisting "! Shape of the training set (#sequences, #timesteps in a sequence, #features): Shape of the corresponding labels (as a one-hot vector for 6 categories): The rest of the parameters (learning rate, batch size) are the same as the defaults in Keras: batch_size: Integer or None. Making location easier for developers with new data primitives, Stop requiring only one assertion per unit test: Multiple assertions are fine, Mobile app infrastructure being decommissioned. also many of optim methods need big batch size for good convergence. Earliest sci-fi film or program where an actor plays themself. If you use all the samples for each update, you should see it decreasing and finally reaching a limit. When the validation loss is not decreasing, that means the model might be overfitting to the training data. Train Epoch: 9 [200/249 (80%)] Loss: 0.480884 Test set: Average loss: Loss and accuracy during the training for these examples: There are several reasons that can cause fluctuations in training loss over epochs. The loss is stable, but the model is learning very slowly. 3) Add a weight decay term to your optimizer call, typically L2, as youre dealing with Convolution networks have a decay term of 5e-4 or 5e-5. We really can't include code in our answers. cuda package supports CUDA tensor types but works with GPU computations.. "/> Let's say within your data points, you have a mislabeled sample. So in your case, your accuracy was 37/63 in 9th epoch. Why? It helps to think about it from a geometric perspective. Math papers where the only issue is that someone else could've done it but didn't, Fourier transform of a functional derivative, Employer made me redundant, then retracted the notice after realising that I'm about to start on a new project. Then try the LSTM without the validation or dropout to verify that it has the ability to achieve the result for you necessary. This can be diagnosed from a plot where the training loss is lower than the validation loss, and the validation loss has a trend that suggests further improvements are possible. How many characters/pages could WordStar hold on a typical CP/M machine? This suggests that the initial suspicion that the dataset was too small might be true because both times I ran the network with the complete librispeech dataset, the WER converged while validation accuracy started to increase which suggests overfitting. PyTorch Lightning has logging to TensorBoard built in. Asking for help, clarification, or responding to other answers. I prefer women who cook good food, who speak three languages, and who go mountain hiking - what if it is a woman who only has one of the attributes? rev2022.11.3.43005.

Is this model suffering from overfitting? This function returns a variable called history that contains a trace of the loss and any other metrics specified during the compilation of the model. to your account. Stack Overflow for Teams is moving to its own domain! Irene is an engineered-person, so why does she have a heart problem. Note that there are other reasons for the loss having some stochastic behavior. Train Epoch: 7 [0/249 (0%)] Loss: 0.537067 Train Epoch: 7 [100/249 Is a planet-sized magnet a good interstellar weapon? Best way to get consistent results when baking a purposely underbaked mud cake. Hope that makes sense. Why does PyTorch lightning not show validation loss? How can I best opt out of this? I thought that these fluctuations occur because of Dropout layers / changes in the learning rate (I used rmsprop/adam), so I made a simpler model: I also used SGD without momentum and decay. What is the accuracy of Python-PyTorch-loss? Even I moved recently to pytorch from Keras, took some time to get used to it. What do you need to know about Java serversocket? Large network, small dataset: It seems you are training a relatively large network with 200K+ parameters with a very small number of samples, ~100. device = torch. Improving Validation Loss and Accuracy for CNN, Pytorch CrossEntropyLoss expected long but got float, Val Accuracy not increasing at all even through training loss is decreasing, Math papers where the only issue is that someone else could've done it but didn't, SQL PostgreSQL add attribute from polygon to all points inside polygon but keep all points not just those that fall inside polygon. So in your case, your accuracy was 37/63 in 9th epoch. Perhaps you're returning. Why does PyTorch have no learning progression? How to help a successful high schooler who is failing in college? Very small batch_size. device ( Union[str, torch.device]) - specifies which device updates are accumulated on. 2) Zero gradients of your optimizer at the beginning of each batch you fetch and also step optimizer after you calculated loss and called loss.backward(). Is the model suffering from overfitting in machine learning? Try reducing the problem. rev2022.11.3.43005. This sample when combined with 2-3 even properly labeled samples, can result in an update which does not decrease the global loss, but increase it, or throw it away from a local minima. The model is updating weights but loss is constant. 2 How can underfit LSTM model be diagnosed from a plot? I tried increasing the learning_rate, but the results don't differ that much.
