Uncategorized 1 second ago

model = Sequential() The attributes I need are in specific columns and of different datatype. ], How to define a neural network using Keras for multi-class classification. I recommend testing a suite of different algorithms in order to discover what works best for your dataset. Hello Jason Brownlee, Confirm the size of your output (y) matches the dimension of your output layer. ) I then installed Theano 1.0.1, and got the same result again. assert K.backend() == backend, set_keras_backend(“theano”) First of all, thanks for all the great effort you put in ML. But at the end, model give the accuracy. You may need to tune the model for your problem. 9.9828100e-01 7.4096164e-08 5.5998818e-05 3.6668104e-01 1.2538023e-01 This is a multi-class classification problem, meaning that there are more than two classes to be predicted, in fact there are three flower species. X_train = mat[‘X’]. You don’t need all three types. Nevertheless, the best advice is always to test each idea and see what works best on your problem. I am working this through in a Jupyter notebook. print(“Baseline: %.2f%% (%.2f%%)” % (results.mean()*100, results.std()*100)), and my csv is : Shouln’t it be 6 instead of 7? # load dataset Para-swimming classification is a function-based classification system designed to allow for fair competition in disability swimming. results = cross_val_score(estimator, X, dummy_y, cv=kfold) ], [[ 0.00432587 -0.04444616 0.02091608] Or can you save the whole wrapped model. Thanks for the great tutorial. This is happening with Keras 2.0, with Keras 1 works fine. How to reach that level ? my task is to build a model that classifies different EMG. This will show you how to make a single prediction: I’ve been trying to create a multi class classifier using your example but i can’t get it to work properly. with open(“name.p”,”wb”) as fw: Is there any specific method or approach? I’m exactly newbie to Keras, and I want to figure out confusion matrix by using sklearn.confusion_matrix(y_test, predict). model.add(Dense(8, input_dim=8, activation=’relu’)) The example in the post uses “epochs” for Keras 2. What should I do to not receive this message? TypeError: object of type ‘NoneType’ has no len(). The second one came at the end, during the Kfold validation. losses =, y_pred), So I am looking to learn things like “how many layers and nodes should i have” and “what are other important feature engineering tools aside from StandardScaler().”, Here is a slice of the data (not the real dataset), By implementing neural network in Keras, how can we get the associated probabilities for each predicted class?’. Now system doesn’t see this file, when I write “dataframe=pandas.read_csv….”, 4. Can we apply gridsearch on a multiclass dataset ? I will read and try it. What a nice tutorial! i did n’t understanding neural network? According to keras documentation, I can see that i can pass callbacks to the kerasclassifier wrapper. Thanks for the reply. model.add(Dense(4, input_dim=4, kernel_initializer=’normal’, activation=’relu’)) I am able to do that in pytorch by using your article on pytorch. batch_size=1000, nb_epoch=25, Any improvements also I would like to put LSTM how to go about doing that as I am getting errors if I add I want to ask you, how can this model be adapted for variables that measure different things? one hot encoded) How can I do that? model = Sequential() 0 1 1 1 1 0 1 0 1 0 1 0 2 0 2 1 0 1 0 1 1 1 1 1 0 0 1 0 1 1 1 1 0 0 1 1 1 I mean what if X contains multiple labels like “High and Low”? model.add(Dense(30, input_dim=15, activation=’relu’)) # not sure if 30 too much. model.add(Dense(3, kernel_initializer=’normal’, activation=’sigmoid’)) I hope to cover it in the future. # optimizer=keras.optimizers.Adam(), classifier.add(Dense(output_dim=4,init=’uniform’,activation=’relu’,input_dim=4)) Changing the source to UCI Machine Learning repository solved my problem. ValueError: Invalid shape for y: (), I had one hot encoded the Y variable( having 3 classes). Help me please. The hidden layer uses a rectifier activation function which is a good practice. File “/Library/Python/2.7/site-packages/scikit_learn-0.17.1-py2.7-macosx-10.9-intel.egg/sklearn/externals/joblib/”, line 72, in __call__ Traceback (most recent call last): File “F:\ML\keras-frcnn-moded\keras_frcnn\”, line 55, in class_loss_cls All models have error. Debugging is also turned off when training by setting verbose to 0. Feels like the folds would be too small to get 10 good chunks that represent the data. You have really helped me out especially in implementation of Deep learning part. of layers and activation type are specified. # Fit the model Consider checking the dimensionality of both y and yhat to ensure they are the same (e.g. File “C:\Users\hp\AppData\Local\Programs\Python\Python36\lib\site-packages\keras\wrappers\”, line 75, in check_params [1,1,1] Probably start off treating the labels as nominal, one hot encoding, 4 nodes in the output layer. model.add(Dense(64, activation=’relu’, input_dim=46)) #there are 46 feature in my dataset to be trained ), sorry, I don’t have an example for pytorch, but I have an example for keras that might help: Is this reasonable? I follow your code but unfortunately, I get only 68%~70% accuracy rate. I guess subtracting sample from training to allocate unsee validation sample must be the cause…do you agree? array([[ 0., 0., 0., …, 0., 0., 0. See this post on why: But with Keras 2.0.2, the results are absymally bad. from keras.wrappers.scikit_learn import KerasClassifier Please can you guide me with the same. So you use 5*200=1000 examples for training. keras.optimizers.Adam(lr=0.001) Though, I’d be surprised. The 50% means that there is a possibility 50% to have how number of faces??? Any solution? This is a common question that I answer here: However, I feel it’s still 3-layer network: input layer, hidden layer and output layer. results = cross_val_score(estimator, X, dummy_y, cv=kfold), or using train/test split and validation data like this, x_train,x_test,y_train,y_test=train_test_split(X,dummy_y,test_size=0.33,random_state=seed),,y_train,validation_data=(x_test,y_test)). Let’s say I have this problem.I have images with structures (ex building), structure: 0 is there is no structure , 1 if it is # model.add(Dense(10, activation=’softmax’)) model = Sequential() Epoch 3/50 One batch involves showing a subset of the patterns in the training data to the model and updating weights. from sklearn.preprocessing import LabelEncoder e.g. Hello jason, Also in another post I also see you use this code: history =, trainy, validation_data=(testX, testy), epochs=100, verbose=0). For more information on multi class competition in your state contact your state or territory swimming association. Do you think speed would increase if we use DBN or CNN something ? model.add(Dropout(0.5)) That means we can use the standard model.predict() function to make predictions from scikit-learn. Typically, a one hot encoding for binary classification is equivalent to predicting a probability 0-1. return [func(*args, **kwargs) for func, args, kwargs in self.items] Explore your option below for more information. In your opinion what is the reason of getting such values?? 2018-01-15 00:01:58.609360: I tensorflow/core/platform/] Your CPU supports instructions that this TensorFlow binary was not compiled to use: SSE4.1 SSE4.2 AVX Hi Jason, thank you for your great instruction Because your example uses “Softmax regression” method to classify, Now I want to use “multi-class SVM” method to add to the neural network to classify. Swimmers can participate in local level programs and compete in state, national and international competitions. Its better formatted here! I wanted to learn on how to plot graphs for the same. 126 print(‘Accuracy: %f’ % accuracy) What versions of Keras/TF/sklearn/Python are you using? Thanks for the great work on your tutorials… for beginners it is such in invaluable thing to have tutorials that actually work !!! Hey Jason! Note: Your results may vary given the stochastic nature of the algorithm or evaluation procedure, or differences in numerical precision. estimator = KerasClassifier(build_fn=baseline_model, nb_epoch=200, batch_size=5, verbose=0) estimators.append((‘standardize’, StandardScaler())) If we wish, we could pretty-print this vector and summarize the predicted confidence that the photo would be assigned each label. I will appreciate so much any answer from your side. Sorry, I am newbie. # create model What makes sense most to me is sigmoid activation (not exclusive) + binary_crossentropy (treat each output neuron as binary problem), but I’ve read multiple stackoverflow and other articles suggesting conflicting informations. Multi Class Point Score back. Your guides have been a tremendous help to me. …………………………………………………….. The error is: Traceback (most recent call last): Not sure why the results are so bad. I am classified in Multi Class swimming this means people who have disability’s can race against other people with the same classification as them. _pywrap_tensorflow = swig_import_helper() You said the network has 4 input neurons , 4 hidden neurons and 3 output neurons.But in the code you haven’t added the hidden neurons.You just specified only the input and output neurons… Will it effect the output in anyway? Hi Jason! Once I have installed Docker (tensorflow in it),then run IRIS classification. My code looks like this (basically your code ) : seed = 7 print(‘Precision: %f’ % precision) If I remove the argument init = ‘normal’ from model.add() I get the correct result but if I add it then I get error with the function. Thanks. (in this case 4). history =, y, **fit_args) The first line defines the model then evaluates it using cross-validation. Jason this tutorial is just amazing! def baseline_model(): # define baseline model It is also within the realm of known top results for this problem. Para swimming competition is for elite swimmers with physical, visual and intellectual impairment but all Australian Para-swimmers start out in multi class swimming. This article is in continuation of my previous article that explained how target encoding actually works.The article explained the encoding method on a binary classification task through theory and an example, and how category-encoders library gives incorrect results for multi-class target. What is Multi Class Swimming? Good question, I answer it here: If we could be able to nail the cause, it would be great. Remember to change loss to binary_crossentropy. from sklearn.model_selection import cross_val_score Should i continue with this training set? It is impossible for me to say, try it and see. Consider using an integer encoding followed by a binary encoding of the categorical inputs. ], array([[ 0., 0., 0., 0., 1. from sklearn.pipeline import Pipeline Unless the number of classes is 2, in which case you can use a sigmoid activation function with a single neuron. predictions = estimator.predict(X_test), print(predictions) from keras.layers import Dense ], Only thing that solves the issue, and makes me get similar results to the ones you’re getting in your tutorial, is downgrading to Keras <2.0 (In my case I downgraded to Keras 1.2.2.). Any help would be greatly appreciated. Kindly help me out in this. Hi Jason, Thank your very much for those nice explainations. Hi Jason, thank you so much for your helpful tutorials. It might be easier to use the Keras API and the KFold class directly so that you can see what is happening. print(“Baseline: %.2f%% (%.2f%%)” % (results.mean()*100, results.std()*100)), ————————————————————————— There are 4 categories of the impact column with subcategories of each The softmax is a standard implementation. …, I’ve learnt a great deal of things from you. You can learn more about sigmoid here: model.add(Dense(15,input_dim=400,init=’normal’,activation=’relu’)) Clubs across Australia offer the chance for swimmers with disability to join in and give swimming a go., Y, epochs=150, batch_size=5) The number of patterns in the dataset for one epoch must be a factor of the batch size (e.g. Hi Jason, I have run the model for several time and noticed that as my dataset (which is 5 input, 3 classes) I got standard deviation result about over 40%. # Compile model ], print(clf_saved), prob_pred=clf_saved.predict_proba(X_test)[:,1]. After fitting a large volume of data, I want to save the trained neural network model to use it for prediction purpose only. Is there some way to visualize and diagnose the issue? A/B Perhaps some of these tips will help: new_object_params = estimator.get_params(deep=False), TypeError: get_params() got an unexpected keyword argument ‘deep’. #learning schedule callback “epsilon”: 1e-07, if i try this: print(‘predict: ‘,estimator.predict([[5.7,4.4,1.5,0.4]])) i got this exception: AttributeError: ‘KerasClassifier’ object has no attribute ‘model’ I know OHE is mainly used for String labels but if my target is labeled with integers only (such as 1 for flower_1, 2 for flower_2 and 3 for flower_3), I should be able to use it as is, am I wrong? # create model # summarize results I am unable to trace why the error is occurring. I used ‘normal’ to initialize the weights. Review the outputs from the softmax, although not strictly probabilities, they can be used as such. This is called NLP, learn more here: # create model from keras.models import Sequential A one hot encoding is not required, you can train the network to predict an integer, it is just a MUCH harder problem. [ 0.10440681, 0.11356669, 0.09002439, 0.63514292, 0.05685928], import os, def set_keras_backend(backend): 2) How can I get (output on screen) the values as a result of the activation function for the hidden and output layer ? 0. model = Sequential() model.compile(loss=’categorical_crossentropy’, optimizer=’adam’, metrics=[‘accuracy’]), X_train, X_test, Y_train, Y_test = train_test_split(X, dummy_y, test_size=0.33, random_state=seed) Hey!!! # fix random seed for reproducibility import backend dataset = numpy.loadtxt(“tursun_deep_p6.csv”, delimiter=”,”) It’s a great tutorial. Your help would be greatly appreciated! Hence I had to borrow from the Matlab link. You can contact me here to get the most recent version: Yes, deep learning algorithms are stochastic: Yes, use the sklearn MinMaxScaler. matplotlib: 2.0.0 I have many examples on the blog of categorical outputs from LSTMs, try the search. File “C:\Users\ratul\AppData\Local\Programs\Python\Python35\lib\site-packages\keras\wrappers\”, line 147, in fit [ 0., 0., 0., …, 0., 0., 0. The reason is that we can access all of sklearn’s features using the Keras Wrapper classes. This process will help you work through your modeling problem: Hi YA, I would try as many different “views” on your problem as you can think of and see which best exposes the problem to the learning algorithms (gets the best performance when everything else is held constant). Swimming WA. Dear Jason, [”, u’gnu_linux-k4.9′, u’dssss’, u’USB_IO_Error’, u’syssw’], The second fits the model on a train dataset and evaluates it each epoch using a validation dataset. Appreciate your hard work on these tutorials.It really helps. I got extra benefit from it, but I need to calculate precision, recall and confusion matrix for such multi-class classification. Dear Jason, Looks like you might need to one hot encode your output data. Yes, you could be right, 15 examples per fold is small. Thanks. Most imbalanced classification examples focus on binary classification tasks, yet many of the tools and techniques for imbalanced classification also directly support multi-class classification problems. Also, imbalanced classes can be a problem. You can use basic Keras, but scikit-learn make Keras better. history =,ytrain, epochs=400, batch_size=100), This is what my training accuracy looks like: I’m sorry to hear that, perhaps check the data that you have loaded? results = cross_val_score(estimator, X, dummy_y, cv=kfold). I was facing error this when i run it . Check your code file. Therefore I wanted to optimize the model and add cross validation which unfortunately didn’t work. How to evaluate a Keras neural network model using scikit-learn with k-fold cross validation. # create model Thank you for such a wonderful and detailed explanation. Special Olympics is a global movement offering opportunities for people with disability to get involved in sport. Each instance is a type of atom that are located close to each other. —-> 1 results = cross_val_score(estimator, data_trainX, newy, cv=kfold) File “/usr/local/lib/python2.7/site-packages/keras/backend/”, line 17, in Hello, Jason. Then I edited the second layer’s activation to ‘softmax’ instead of sigmoid and I got 97.33% (4.42%) performance., Hi Jason! I can’t find my mistake. model.add(Dense(100, activation=’relu’)) TypeError: __call__() takes at least 2 arguments (1 given). Epoch 7/10 Neural networks are stochastic: above this error message when asking for help. same goes for epoch ; how do you choose nbr of iterations; There are no good rules, use trial and error or a robust test harness and a grid search. model.add(Dense(50, input_dim=15, kernel_initializer=’normal’, activation=’relu’)), I want to plot confusion metrics to see the distribution of data in different classes. Classification Masters Swimming Victoria, Level 2 Sports House,375 Albert Road, Albert Park 3206 Phone: (03) 9682 5666 Email: I ran into some problem while implementing this program Perhaps try defining your data in excel? Thanks. [ 0., 0., 0., 0., 1. Will look into it and post my hopefully sucessfull results here. Hi, Jason! Can you explain why you didn’t use train_test_split method? import pandas My model doesn’t learn thereafter. Hi Jason, import pandas from sklearn.model_selection import cross_val_score Swimming WA Foundation - help us fund a multi-class classification day! In your example it doesnt. # create model Something like this: df = pandas.read_csv, slice, blah blah blah model.compile(blah blah blah) have a nice day, I’ve run a Random Forest classifier on my data and already gotten a 92% accuracy, but my accuracy is absolutely awful with my LSTM (~11%, 9 classes so basically random chance). (6): BatchNorm1d(100, eps=1e-05, momentum=0.1, affine=True, track_running_stats=True) Thank you. 0 1 0 0 1. I found it gave better skill with some trial and error. 521/521 [==============================] – 11s – loss: 0.0311 – acc: 0.9981 I 20% means possibility to have structure? The Tensorflow is a Python3.6 recompile picked up from the web at: Running the whole script over and over generates the same result: “Baseline: 59.33% (21.59%)”. And my predictions are also in the form of HotEncoding an and not like 2,1,0,2. I was wondering perhaps you posted an article about it/something similar that I can use as a reference. ytrain2=encoder.fit_transform(ytrain2).toarray(), classifier=Sequential() Perhaps you need to update your version of scipy. Yes, to get started with one hot encoding, see this: do you agree? I got your model to work using Python 2.7.13, Keras 2.0.2, Theano…, by copying the codes exactly, however the results that I get are not only very bad (59.33%, 48.67%, 38.00% on different trials), but they are also different. Using tensorflow as keras backend serves useful but it’s quite slow for the model (takes days for training). I was wondering if you could show a multi hot encoding, I think you can call it al multi label classification. Can you suggest a way to handle his? I see the problem, your output layer expects 8 columns and you only have 1. Next, the prediction is rounded and the vector indexes that contain a 1 value are reverse-mapped to their tag string values. and I help developers get results with machine learning. Now I want to change the number of classes from 4 to 2 !! (1): Embedding(2, 1) Address: PO Box 206, Vermont Victoria 3133, Australia. from sklearn.model_selection import cross_val_score import keras.backend as K from sklearn.cross_validation import train_test_split I must also say that the last column has 23 different classes. and what is a good amount of nodes for such a high input shape :/ tried to split it up to multiple layers so its not 8139 -> 4000-> 14, Consider the options in this post for imbalanced data: print(“Baseline: %.2f%% (%.2f%%)” % (results.mean()*100, results.std()*100)), X_train, X_test, Y_train, Y_test = train_test_split(X, dummy_y, test_size=0.55, random_state=seed) 0. Thank you! Changing the form of the output would require a change to loss function as well. 4 inputs -> [8 hidden nodes] -> [8 hidden nodes -> [12 hidden nodes] -> 3 outputs. Details: But isnt it strange, that when I use the same code as yours, my program in my machine returns such bad results! Dear Jason, please how we can implemente python code using recall and precision to evaluate prediction model, You can use the sklearn library to calculate these scores: from keras.layers import Dense How to find the number of neurons for hidden layer(s)? I am taking reference from your post for my masters thesis. Y = dataset[1:,4], However, I am still unable to run since I am getting the following error for line, “—-> 1 results = cross_val_score(estimator, X, dummy_y, cv=kfold)” I try to classify different kind of bills into categorys (that are given !! Please help. from sklearn.cross_validation import cross_val_score, KFold, File “C:\Users\pratmerc\AppData\Local\Continuum\Anaconda3\lib\site- However, the accuracy of my model converges after achieving the accuracy of 57% and loss also converges after some point. from keras.layers import Dense I tried doing: ValueError: Error when checking target: expected dense_2 to have shape (None, 3) but got array with shape (90, 40). you have any example code please share the link. You may also want to use sigmoid activation functions on the output layer to allow binary class membership to each available class. [agree, disagree) –(classification model, that now classifies only these two) –> output would be all 4 original classifications without ‘related’. where the fifth column is one I added in order to check the string attributes. If you are working with time series classification data, you can get started here: I was just wondering. To make the prediction I used this function Y_pred = model.predict (x_test) fyh, fpr = score(yh, pr) I run your source code, now I want to replace “activation=’softmax'” – (model.add(Dense(3, activation=’softmax’)) with multi-class SVM to classify. How many baseline scores would you consider as minimum to obtain the average? there are total of 46 columns. Excellent tutorials! Facebook | Yes, this tutorial will show you how to load images: There are no rules for the number of neurons in the hidden layer. This may help as a starting point that you can adapt to your problem: # create model # create model The model in this tutorial a neural network or a multilayer neural network, often called an MLP or a fully connected network. array([[ 0. thanks a lot. Your batch size is probably too big and your number of epochs is way too small. I designed the LSTM network. Is this necessary to evaluate a multiclass model for text classification, or will other methods suffice? Have you written other more advanced keras classification tutorials? Scaling is not a silver bullet, always good to check with and without, especially when using relu activations. if i try to add more layers along with them i get a warning for indentation fault. have a nice day, [ 0.01232713 -0.02063667 -0.07363331] Other questions: How to save the training template to use in the future with other test data? Problem – Given a dataset of m training examples, each of which contains information in the form of various features and a label. I posted here a while back and I’m back for more wisdom! Do you know have I can force the Keras library to take Theano as a backend rather than the Tensorflow library? [ 0., 0., 0., …, 0., 0., 0. I am a beginner in Keras. Swimmers who are deaf or hard of hearing can compete at the Deaflympic Games and Deaf World Swimming Championships. 521/521 [==============================] – 11s – loss: 0.0352 – acc: 0.9962 The index range seems to be different in my case. Welcome! When I have no structure all rest values are nan. You may have a copy-paste example. Perhaps it is something simple like a copy-paste error from the tutorial? The predicted tags are then printed. Usually, for multiclass classification problem, I found implementations always using softmax activation function with categorical_cross entropy.
