Simply fantastic. You are a blessing. I have been struggling with H2O for quite some time. Your explanation has been easy-to-understand and really useful! Thank you very much.

Hi Jeff! We are researchers in human-computer interaction (HCI) looking for people who have taken an initiative to recently learn Machine Learning on their own, for career, course or curiosity. People from any major/background may participate. Tell us here about your experiences and any difficulties you faced while self-teaching ML and how you overcame them, and have a chance to win $50 giftcard. You can help this project by taking out 5-10 minutes to participate in our study. For more details, see here: www.surveymonkey.ca/r/SelfLearning_ML Please share this request with your colleagues or friends who fit this description. The survey will be open until July 20, 2020.

Sir , How does automl handles the class imbalance problem? Does. It use techniques like random overaampling , undersampling , synthetic generation or just by tuning the class_weight parameter in algorithms such as xgboost ,lgb or ranfom forest. ?

Pradeep.. Most automl out there does undersampling or oversampling. In case of H2O automl it is controlled by "balance_classes " parameter along with few other parameters on how to control it. I am not sure of class_weight can be controlled in H2O as we can directly in xgboost using scale_pos_weight. Will try and update if I find any

Hey! you have an excellent video. I am new to machine learning, my question is does H2O handles the one-hot encoding or there are some ways we can one-hot encode the dataset for the categorical values? I've seen the documentation but couldn't understand. Thank You!
@AIEngineeringLife
@AIEngineeringLife 4 жыл бұрын
depends on the model you are using you can pass it is a parameter in model and H2O takes care of it Say in GBM you can pass parameter as below H2OGradientBoostingEstimator(categorical_encoding = "One_Hot_Implicit")

h20 states it's different from pandas as it does not store data in memory. So where does it store the data when running h20 in colab? Would the same be true when running it locally (is that even possible)? Thanks. And great channel. Really like it! BR

H2O data frame is a distributed data frame and stores data in its cluster nodes. On single node, local node is cluster nodes and it reads data during processing and stores it in memory so algorithms run fast. So it will be very similar to pandas on single node but on distributed memory is distributed and processing happens on each node. They have confused all with their statement in website :) . Here is from their documentation "H2O’s core code is written in Java. Inside H2O, a Distributed Key/Value store is used to access and reference data, models, objects, etc., across all nodes and machines. The algorithms are implemented on top of H2O’s distributed Map/Reduce framework and utilize the Java Fork/Join framework for multi-threading. The data is read in parallel and is distributed across the cluster and stored in memory in a columnar format in a compressed way. H2O’s data parser has built-in intelligence to guess the schema of the incoming dataset and supports data ingest from multiple sources in various formats."

@@AIEngineeringLife Thanks a lot for your detailed response. In colab we normally have only one node like in desktop or not? H2o.init() creates the cluster. So we would not have to build our own hadoop cluster or spark context? BR

Sir, I have couple of questions : 1. Why did you remove Customer_Id from X_train? 2. Is H20 directly does hyperparameter tuning for all models? 3. How does feature engineering works here? 4. How can we know which optimization techniques it does? 5. What if for prediction and time series data sets we have? same way of it or any different? Thanks in advance !!
