QUESTION
My problem is as follow: I have several datasets (900K, 1M7 and 1M7 entries) in csv format which I load into multiple Dask Dataframe. Then I concatenate them all in one Dask Dataframe that I can feed to my Snorkel Applier, which applies a bunch of Labeling Function to each row of my Dataframe and return a numpy array with as many rows as there are in the Dataframe and as many columns as there are Labeling Functions.
The call to Snorkel Applier seems to take forever when I do that with 3 datasets (more than 2 days...). However if I just run the code with only the first dataset, the call takes around 2 hours. Of course I don't do the concatenation step.
So I was wondering how can this be ? Should I change the number of partitions in the concatenated Dataframe ? Or maybe I'm using Dask badly in the first place ?
Here is the code I'm using:

I installed snorkel using conda and when I try to run - from snorkel.labeling import labeling_function
it throws the following error - ModuleNotFoundError: No module named 'snorkel.labeling'
.
I tried looking up for a solution on Github, but unfortunately, I couldn't follow through. I have also tried installing nb_conda_kernels
, to make all your conda environments available in jupyterbut it didn't help. Also tried creating a separate env, installing snorkel and launching jupyter notebook from the snorkel's environment, and it didn't work either. Any form of help is much appreciated!
Thanks in advance!

I have a set of features to build labelling functions (set A) and another set of features to train a sklearn classifier (set B)
The generative model will output a set of probabilisitic labels which i can use to train my classifier.
Do i need to add in the features (set A) that i used for the labelling functions into my classifier features? (set B) Or just use the labels generated to train my classifier?
I was referencing the snorkel spam tutorial and i did not see them use the features in the labelling function set to train a new classifier.

ANSWER
Answered 2020-Jan-21 at 01:19From your linked snorkel tutorial, the labeling functions (which maps input to labels ("HAM", "SPAM", "Abstain") are used to provide labels instead of features.
IIUC, the idea is to generate labels when you do not have good quality human labels. Though these "auto-generated" labels would be quite noisy, it could be served as a starting point of a labeled dataset. The learning process is to take this dataset and learn a model, which encodes the knowledge embedded in these labeling functions. Hopefully the model could be more general and the model could be applied to unseen data.
If some of these labeling function (can be considered as fixed rules instead) are very stable (regarding prediction accuracy) in certain conditions, given enough training data, your model should be able to learn that. However, in production system, to overcome the possibility of model instability, one easy fix is to override machine prediction with human labels on seen data. The same idea can be applied too if you think these labeling functions could be used for some specific input (pattern). In this case, the labeling functions would be used to directly get labels to override machine predictions. This process can be implemented as a pre-check before your machine-learned model runs.

QUESTION
I am currently working on the project listed below. So far I am having trouble accessing my class from my program. I'm not sure if it's something that I am missing or if I'm just in over my head. I will include the code I have came up with so far.
You will be graded on:
- Your code must compile. If your code has a compile error and does not run, you will not receive a passing score.
- Your code must follow the guidelines provided. For example: Your final code must contain 3 classes. If all your code is done from within the main() with a series of WriteLine() methods, you will not do well.
Waikiki Hilton Beach Rentals Application:
You will be creating a program for Waikiki Hilton Beach Rentals. Here guests of the Hilton can rent beach equipment such as flotation rafts, snorkel gear, chairs, umbrellas and paddle boats.
Your application will get the guest name, items rented, qty of each item rented and total minutes rented. A guest can rent as many items as they would like, and multiple quantities. You can assume that all items are rented for the same time frame. So a guest can rent 2 chairs, and snorkel gear – but all for 65 minutes. (not chairs for 15, and the snorkel gear for 45 for example)
You will be creating three classes, the BeachRentalsApp which will be the entry point of the program, a Rental class which you will be using to create rental objects, and a guestclass which holds the guest information.
BeachRentalsApp – where the program begins. This should create a guest object. Your guest object holds the guest name, contract number and an array of Rental objects. The app should display a welcome message, and then get the guest info as well as the rental info. All of the info displayed and gathered in the main() method should be called from methods within the BeachRentalsApp class.
Contains the following methods:
- main() – instantiates a Guest object, and as many Rental objects as required. Rental objects are then stored in an array data element in the Guest object ie itemsRented[ ]. The main method should call methods to get input and display data. Methods to call in this class should include:
- Display a welcome message
- Get the guest name
- Get the contract number
- Gets minutes rented – a guest has to rent for a minimum of an hour and no more than 8 hours.
- Gets the item to rent and qty
- displays the static array from the Rental Class
- gets the qty and item to rent
- Displays the final rental info:
- Guest name
- For each item: item rented, total cost of rental (price of item * rental period)
- A final total of all items rented
Guest – A class that holds guest info
Properties:
- Guest Name
- Contract Number (ie K168)
- # Hours rented
- # Minutes rented
- Items Rented (an array of rental objects)
Constructors as appropriate: requires a minimum of guest name to instantiate a guest object.
Methods:
- Sets the contract Number. If no number is provided, create a random contract number. It should start with the first letter of the customer name, and then a randomly generated additional 4 numbers.
- Accepts the minutes rented and sets the class data fields (# hours rented, # minutes rented) accordingly.
Rental – A class that describes a rental
Constructors as appropriate. Users of this class need a minimum of a rental item to instantiate an object.
Static members:
- an array of the rental items available (such as flotation rafts, snorkel gear, chairs, umbrellas, paddle boats)
- The hourly rate for each of the following is:
- flotation raft – $15
- snorkel gear – $25
- chairs – $8
- umbrella – $10
- paddle boat - $40
Properties:
- item Rented (ie umbrella)
- qty rented (ie 3 umbrellas)
- total rental price (ie umbrella cost $10 * rental period * 3 umbrellas)
Methods
- static method that displays the items available for rental
- calculates total price - calculated in half hour increments. For example. An umbrella costs $8 per hour. If the rental period is 30 minutes, the price is $4. Otherwise the price is $8. So a rental of 75 minutes costs $12. (1 hour is $8 and additional up to 30 minutes is $4) A rental of 45 minutes costs $8.

Answered 2019-Apr-01 at 23:02Well an object is a class that contains descriptive data about a certain item. For example a Guest object will have things like name, the data structure containing their rental list.. etc.
So, where you should start is by creating the Guest object as defined by the assignment and the Rental object as defined by the assignment.
Assuming you have created your objects, you need to access them, how you do this is by:
QUESTION
I have a UITableView that contains a list of categories (in this example, list of sports types i.e. Water and Land based)
Each cell in this table then has a list of sports associated with the type of sport displayed in a nested UICollectionView. For example, water based will have Surfing and swimming.
Think Netflix - with Vertical scrolling categories with horizontally scrollable subcategories.
Here is example JSON (Note that the JSON shown is just to describe the structure. I have in fact stored this in RealmDb)
...ANSWER
Answered 2019-Feb-21 at 14:52In my opinion a tableview should only be used when you want to take advantage of its main features: Recycling in order to support a large number of cells, and other features like search, alphabetizer, etc. I would rather use a vertical stack view and manage your collection views yourself, rather than having them in cells. I would imagine having your collection views recycled as you scroll would be a nightmare - because the same cell instance would be reused - but now it would have the wrong collection view in it, as you scroll down.
If you will only have less than 10 rows in this table view, I would use a Vertical orientation Stackview. You don't need cells or recycling. When I used table views for vertical layouts before, I ran into problems with state cleanup and bleeding of elements across recycled cells.
I would probably break out each collection view's delegate into a separate class.
To answer your main question: If you still want to use a tableview, set the reuseIdentifier to a unique value for each row, so recycling doesn't take place. And manage an array of data source objects, to assign to each of your collection views in cellForRow of your tableView method.
Another option is to have each cell be the dataSource for each collection view - so it's completely self contained, by making a custom UITableViewCell subclass that serves as both a datasource and UI container for your collection view. Then injecting a universal data model into that cell in cellForRow method (that would work for all types of collection views - regardless of data type).
I'd keep the datasources as separate objects though, and inject them into the cells, because to me a cell should just be a "shell" - a UI layout element and shouldn't hold the details of a dataSource (that way the dataSource can be re-used in other places too, not just that cell)
