unpivot a dataframe with many columns into one with only 3 - python-3.x

If I have a Dataframe which looks like:
clientid CLNT1 CLNT2 CLNT3 CLNT4 ... CLNTN
tradedate ...
2019-07-01 0.0 0.0 0.0 0.0 ... 12.0
2019-07-02 0.0 0.0 0.0 0.0 ... 0.0
2019-07-03 0.0 0.0 0.0 0.0 ... 0.0
2019-07-05 0.0 0.0 0.0 0.0 ... 0.0
2019-07-08 0.0 0.0 0.0 0.0 ... 0.0
... ... ... ... ... ... ...
2020-01-31 0.0 0.0 0.0 0.0 ... 0.0
2020-02-03 0.0 0.0 0.0 0.0 ... 0.0
2020-02-04 0.0 0.0 0.0 0.0 ... 0.0

2020-02-06 0.0 0.0 0.0 0.0 ... 0.0
How can I collapse it into something like:
clientid count
tradedate
2019-07-01 CLNT1 0.0
2019-07-01 CLNT2 0.0
2019-07-01 CLNT3 0.0
2019-07-01 CLNT4 0.0
... ... ...
2019-07-01 CLNTN 12.0
Apologies if this has been answered already. Rather new to pandas...

Calculate mutual information in columns

I have been set a sample exercise by my teacher. It is to reduce dimensionality by writing a function that uses sklearn(mutual information).I am not that good in it but I tried many ways. Its not giving me any reliable answer even. I am unable to find out the mistake.
The data consists of 19 columns that i got with one hot encoding. And i named it as dummy. whenever i run the code it does not give me any output. neither error nor result.
first i am not sure what to set the threshold.
2nd how to call the mutual information source from sklearn and iterate every column in a pair, to drop one out of the highly correlated columns pair.

with shape:
[17544 rows x 34 columns]
Then I scale it with MinMaxScaler as follows:
scaler = MinMaxScaler(feature_range=(0,1))
data = scaler.fit_transform(data)
Then I am using a function to create my train, test dataset with shapes:
X_train : (12232, 24, 34)
Y_train : (12232, 24)
X_test : (1708, 24, 34)
Y_test : (1708, 24)
After I fit the model and I predict the values for the test set, I need to scale back to the original values and I do the following:
test_predict = model.predict(X_test)
test_predict = scaler.inverse_transform(test_predict)
Y_test = scaler.inverse_transform(Y_test)
But I am getting the following error:
ValueError: operands could not be broadcast together with shapes (1708,24) (34,) (1708,24)
How can I resolve it?
The inverse transformation expects the data in the same shape with the one produced after the transform, i.e with 34 columns. This is not the case with your test_predict, neither with your y_test.
Additionally, although irrelevant to your error, you are committing the mistake of scaling first and splitting to train/test afterwards, which is not the correct methodology as it leads to data leakage.
Here are the necessary steps to resolve this:
Split first to train & test sets
Transform your X_train and y_train using two different scalers for the features and output respectively, as I show in this answer of mine; you should use .fit_transform here.
Fit your model with the transformed X_train and y_train (side note: it is good practice to use different names for different versions of the data, instead of overwriting the existing ones).
To evaluate your model with the test data X_test & y_test, first transform them using the respective scalers from step #2; you should use .transform here (not .fit_transform again).
In order to get your predictions y_pred back to the scale of your original y_test, you should use .inverse_transform of the respective scaler on them. There is of course no need to inverse transform your transformed X_test and y_test - you already have these values!

How to handle correctly sparse features to avoid poor performance of classification neural network?

I'm trying to understand how sparse neural networks work. I have a very sparse data of about 40k rows for two classes. The dataset looks like this:

I did a simple neural network model using Keras, but the model isn't learning and accuracy rarely goes beyond 52% on train dataset. I tried two variations of the same model:
Variation 1:
def build_nn(n_features,lr = 0.001):
_input = Input(shape = (n_features,),name = 'input',sparse = True)
x = Dense(12,kernel_initializer = 'he_uniform',activation = 'relu')(_input)
x = Dropout(0.5)(x)
x = Dense(8,kernel_initializer = 'he_uniform',activation = 'relu')(x)
x = Dropout(0.5)(x)
x = Dense(2,kernel_initializer = 'he_uniform',activation = 'softmax')(x)
nn = Model(inputs = [_input],outputs = [x])
nn.compile(loss='sparse_categorical_crossentropy',optimizer=Adam(lr = lr),metrics=['accuracy'])
return nn
Variation 2:
def build_nn(feature_layer,lr = 0.001):
feature_inputs = {}
for feature in feature_layer:
feature_inputs[feature.key] = Input(shape = (1,),name = feature.key)
feature_layer = tf.keras.layers.DenseFeatures(feature_layer)
feature_inputs_n = feature_layer(feature_inputs)
x = Dense(12,kernel_initializer = 'he_uniform',activation = 'relu')(feature_inputs_n)
x = Dropout(0.5)(x)
x = Dense(8,kernel_initializer = 'he_uniform',activation = 'relu')(x)
x = Dropout(0.5)(x)
x = Dense(2,kernel_initializer = 'he_uniform',activation = 'softmax')(x)
nn = Model(inputs = [v for v in feature_inputs.values()],outputs = [x])
nn.compile(loss='sparse_categorical_crossentropy',optimizer=Adam(lr = lr),metrics=['accuracy'])
return nn
The motivation behind doing the variation 2 is because the features are sparse and I thought that this could have an impact on the model's performance, so I followed this tensorflow guide.
Also, the labels are converted to a categorical label using to_categorical function, provided by the keras api:
y_train2 = to_categorical(y_train)
y_test2 = to_categorical(y_test)
My questions are:
Is my model wrong (especially the variation 2) or if I'm doing the wrong representation of the sparse features and how this features should be handled?
The RA and RB are the features of two different classes and since there are rows full of 0, should I add a third class representing an unknown class or remove the rows that contains only 0?
Since RA and RB map two different classes, should I do two separate model, one for columns RA and class 0 and the other for columns RB and class 1?
I'm also posting an image of the train/test model's accuracy:
I can also provide any other part of the code if needed.
EDIT:
I didn't put this part because I felt it doesn't has a relation to what I was asking, but it seems I was wrong.
Each feature is an individual branch from a sklearn decision tree. The class that the decision tree looks for is an up or down for the next candle in a trading enviroment (a candle is a price aggregation of an instrument in time that has an open, low, high and close price). Then, the idea is to grab those branches, that are valuated in the price time series, and evaluate if the condition is met, so if the branch is active the value is 1.
For example, branch RA0 at index 55 is active, so the value is 1. The labels are calculated as np.sign(close - open). So, the idea is that by using multiple branches the classification of the label can be improved, by having a neural network that can see if which branch is active and which one has more weight in order to make a classification.
The use of sparse_categorical_crossentropy is wrong here; the sparsity in sparse_categorical_crossentropy refers to the label representation, and not to the features. Since you are using one-hot encoded labels:
y_train2 = to_categorical(y_train)
y_test2 = to_categorical(y_test)
and a final layer of 2 nodes with activation = 'softmax' (which I take it to mean that you have only 2 classes), you should switch to loss='categorical_crossentropy' irrespectively of the sparsity in your features.
Other general remarks:
Remove dropout, which should never be used by default. Dropout is used to help against overfitting if such a thing is detected; used uncritically (even worse, with such high values), it is well-known to prevent training altogether (i.e. something very similar to what you report here).
Remove kernel_initializer = 'he_uniform' from all layers, thus leaving the default glorot_uniform one (useful hint: default values are there for a reason, and it is not advisable to play with them unless you have a specific reason to do so and you know exactly what you are doing).

To make things a bit more spicy, some of the zeros are NaNs, but usefully the number appears at hour = 12:00
The repeating nature indicates it is erroneous data so needs to be removed.
I was thinking something like:
if data at df.index.hour = 12 is preceded by 23 values where np.nanmean = 0 then make all values in sequence = np.nan
But I am new to python and not sure how to translate this into a script.
Thank you in advance :)

How to profile libraries?

Is there any hidden option that will put cost centres in libraries? Currently I have set up my profiling like this:
cabal:
ghc-prof-options: -O2
-threaded
-fexcess-precision
-fprof-auto
-rtsopts
"-with-rtsopts=-N -p -s -h -i0.1"
exec:
# cabal sandbox init
# cabal install --enable-library-profiling --enable-executable-profiling
# cabal configure --enable-library-profiling --enable-executable-profiling
# cabal run
This works and creates the expected .prof file, .hp file and the summary when the program finishes.
Problem is that the .prof file doesn't contain anything that doesn't belong to the current project. My guess is that there is probably a option that will put cost centers in external library code?
My guess is that there is probably a option that will put cost centers in external library code?
Well, not per default. You need to add the cost centers when you compile the dependency. However, you can add -fprof-auto to the ghc options during cabal install:
$ cabal sandbox init
$ cabal install --ghc-option=-fprof-auto -p --enable-executable-profiling
Example
An example using code from this question, where the code from the question is contained in SO.hs:
$ cabal sandbox init
$ cabal install vector -p --ghc-options=-fprof-auto
$ cabal exec -- ghc --make SO.hs -prof -fprof-auto -O2
$ ./SO /usr/share/dict/words +RTS -s -p
$ cat SO.prof

Unfortunately, you cannot state --ghc-option=… as a flag at the dependencies.
You also need -prof.
GHC Users's Guide says "There are a few other profiling-related compilation options. Use them in addition to -prof. These do not have to be used consistently for all modules in a program.
"
