I've trained an LSTM model with 8 features and 1 output. I have one dataset and split it into two separate files to train and predict with the first half of the set, and then attempt to predict the second half of the set using the trained model from the first part of my dataset. My model predicts the trained and testing sets from the dataset I used to train the model pretty well (RMSE of around 5-7), however when I attempt to predict using the second half of the set I get very poor predictions (RMSE of around 50-60). How can I get my trained model to predict outside datasets well?

If your model is working fine on training data but performs bad on validation data, then your model did not learn the "true" connection between input and output variables but simply memorized the corresponding output to your input. To tackle this you can do multiple things:
Typically you would use 80% of your data to train and 20% to test, this will present more data to the model, which should make it learn more of the true underlying function
If your model is too complex, it will have neurons which will just be used to memorize input-output data pairs. Try to reduce the complexity of your model (layers, neurons) to make it more simple, so that the remaining layers can really learn instead of memorize

I am pretty new to Deep learning. I was experimenting with fine tuning of pretrained models on my own dataset but I am not able to improve the test and training accuracy. Both the Losses are hovering around 62 from beginning of training to last. I am using Xception as the pretrained model and combined with GlobalAveragePooling2D, a dense layer and dropout of 0.2.
The dataset consists of 3522 images belonging to 2 class of training and 881 images belonging to 2 classes of test set. Problem is I am not able add any more images to the datasets. This is the maximum number of images I could add to the datasets. Tried ImageDataGenerator but still it's of no use. Images of two classes looks bit similar in this constraint can I increase the accuracy.
Code:
base_model = Xception(include_top=False, weights='imagenet')
x = base_model.output
x = GlobalAveragePooling2D()(x)
x = Dense(512, activation="relu")(x)
x = Dropout(0.2)(x)
predictions = Dense(2, activation='sigmoid')(x)
model = Model(inputs=base_model.input, outputs=predictions)
for layer in base_model.layers:
layer.trainable = False
model.compile(optimizer='rmsprop', loss='binary_crossentropy', metrics=['accuracy'])
num_training_img=3522
num_test_img=881
stepsPerEpoch = num_training_img/batch_size
validationSteps= num_test_img/batch_size
history= model.fit_generator(
train_data_gen,
steps_per_epoch=stepsPerEpoch,
epochs=20,
validation_data = test_data_gen,
validation_steps=validationSteps
)
layer_num = len(model.layers)
for layer in model.layers[:129]:
layer.trainable = False
for layer in model.layers[129:]:
layer.trainable = True
# update the weights
model.compile(optimizer=SGD(lr=0.0001, momentum=0.9), loss='binary_crossentropy', metrics=['accuracy'])
num_training_img=3522
num_test_img=881
stepsPerEpoch = num_training_img/batch_size
validationSteps= num_test_img/batch_size
history= model.fit_generator(
train_data_gen,
steps_per_epoch=stepsPerEpoch,
epochs=20,
validation_data = test_data_gen,
validation_steps=validationSteps
)
You should make the layers non-trainable before creating the model.
base_model = Xception(include_top=False, weights='imagenet')
for layer in base_model.layers:
layer.trainable = False
x = base_model.output
x = GlobalAveragePooling2D()(x)
x = Dense(512, activation="relu")(x)
x = Dropout(0.2)(x)
predictions = Dense(2, activation='softmax')(x)
model = Model(inputs=base_model.input, outputs=predictions)
Your last layer has 2 units, which suggests, softmax is a better fit.
predictions = Dense(2, activation='softmax')(x)
Try with Adam and change loss.
model.compile(optimizer='adam', loss='categorical_crossentropy', metrics=['accuracy'])
I am trying to classify 2 classes of images. Though I am getting high train and validation accuracy (0.97) after 10 epochs, my test results are awful (precision 0.48) and the confusion matrix shows the network is predicting the images for the wrong class (attached results).
There are only 2 classes in the dataset, each class has 10,000 image examples (after augmentation). I am using the VGG16 network. The full dataset is split 20% to test set (this split was performed by taking random images from each class therefore it is shuffled). The remaining images are split to 80% train and 20% valid sets (as indicated in the ImageDataGenerator line of the code). So in the end there are:
12,904 Train images belonging to 2 classes
3,224 Valid images belonging to 2 classes
4,032 Test images belonging to 2 classes
This is my code:

I suspect that the ImageDataGenerator() is not shuffling the images "before" the train/valid split. If this is the case how can i force the ImageDataGenerator here in Keras to shuffle the dataset before the split?
If shuffling is not the case, how can i solve my issue? what am I doing wrong?
So your model is basically overfitting, which means that it is "memorizing" your training set. I have a few suggestions:
check that your 2 prediction classes are balanced in your training set. I.e. 50-50 split of 0 and 1. For example, if 90% of your training data is labeled 0, then your model will simply predict everything to be 0 and get right in the validation 90% of the time.
if your training data is already balanced, it means that your model isn't generalizing. Perhaps you could try using the pre-trained model instead of custom training every layer of VGG? You can load the pre-trained weights of VGG but do not include top and train only the dense layers.
Use cross validation. Reshuffle the data in each validation and see whether results in the test set improve.
Somehow, the image generator of Keras works well when combined with fit() or fit_generator() function, but fails miserably when combined
with predict_generator() or the predict() function.
When using Plaid-ML Keras back-end for AMD processor, I would rather loop through all test images one-by-one and get the prediction for each image in each iteration.
import os
from PIL import Image
import keras
import numpy
# code for creating dan training model is not included
print("Prediction result:")
dir = "/path/to/test/images"
files = os.listdir(dir)
correct = 0
total = 0
#dictionary to label all animal category class.
classes = {
0:'This is Cat',
1:'This is Dog',
}
for file_name in files:
total += 1
image = Image.open(dir + "/" + file_name).convert('RGB')
image = image.resize((100,100))
image = numpy.expand_dims(image, axis=0)
image = numpy.array(image)
image = image/255
pred = model.predict_classes([image])[0]
animals_category = classes[pred]
if ("cat" in file_name) and ("cat" in sign):
print(correct,". ", file_name, animals_category)
correct+=1
elif ("dog" in file_name) and ("dog" in animals_category):
print(correct,". ", file_name, animals_category)
correct+=1
print("accuracy: ", (correct/total))
I’ve made a custom CNN in PyTorch for classifying 10 classes in the CIFAR-10 dataset. My classification accuracy on the test dataset is 45.739%, this is very low and I thought it’s because my model is not very deep but I implemented the same model in Keras and the classification accuracy come outs to be 78.92% on test dataset. No problem in Keras however I think there's something I'm missing in my PyTorch program.
I have used the same model architecture, strides, padding, dropout rate, optimizer, loss function, learning rate, batch size, number of epochs on both PyTorch and Keras and despite that, the difference in the classification accuracy is still huge thus I’m not able to decide how I should debug my PyTorch program further.
For now I suspect 3 things: in Keras, I use the categorical cross entropy loss function (one hot vector labels) and in PyTorch I use the standard cross entropy loss function (scalar indices labels), can this be a problem?, if not then I suspect either my training loop or the code for calculating classification accuracy in PyTorch. I have attached both my programs below, will be grateful to any suggestions.

I am not fully aware of how the actual core backend works in both libraries however I suppose that the classification accuracy of any model should be almost the same regardless of the library.
I have to build a neural network that can recognize the face of 15 people. I'm using keras. My dataset is composed of 300 total images and is divided into Training, Validation and Test. For each of the 15 people I have the following subdivision:
Training: 13
Validation: 3
Test: 4
Since I couldn't build an efficient neural network from scratch, I also believe because my dataset is very small, I'm trying to solve my problem by doing transfer learning. I used the vgg16 network. In the training and validation phase I get good results but when I run the tests the results are disastrous.
I don't know what my problem is. Here is the code I used:
img_width, img_height = 256, 256
train_data_dir = 'dataset_biometria/face/training_set'
validation_data_dir = 'dataset_biometria/face/validation_set'

I also tried to train some layers instead of not training any, as in the example below:
for layer in model.layers[:10]:
layer.trainable = False
I also tried changing the number of epochs, batch size, nb_validation_samples, nb_validation_sample.
Unfortunately the result has not changed, in the testing phase my network cannot correctly recognize faces.
Without seeing the actual results or errors I can not say what the problem is here.
Definitely, small dataset is a problem, but there are many ways to get around it.
You can use image augmentation to increase the samples. You can refer augement.py.
But instead of modifying your above network, there is a really cool model : siamese network/one-shot learning. It does not need too many pics and the accuracies are great.
Therefore you can see below links to get some help :
