Life2Vec AI FAQ
What is Life2Vec?
Life2Vec is a machine learning model that:
- Encodes sequences of life events into vector representations
- Learns patterns from the event sequences
- Makes predictions about various life outcomes based on those sequences
What data does Life2Vec use?
Life2Vec is trained on:
- A large Danish population registry dataset
- Contains detailed longitudinal records of major life events
- For millions of Danish citizens
- Across multiple years
- Includes events like occupations, incomes, addresses, health conditions etc.
What types of predictions can Life2Vec make?
Life2Vec can predict a variety of outcomes such as:
- Mortality risk
- Future income
- Educational achievement
- Occupations
- Health conditions
- Personality traits
- And more
How accurate are Life2Vec's predictions?
- Life2Vec achieves state-of-the-art performance
- Significantly outperforms previous models
- Accuracy varies per prediction task from 70-90%
Does Life2Vec have access to my personal data?
- No, this online demo does not access or connect to any private user data
- It serves only as an example interface to showcase Life2Vec's capabilities
- The demo generates random, synthetic life event data
Can I use Life2Vec to predict my own life outcomes?
- Unfortunately no, the model can only make predictions based on sequences it has seen before during training
- Since the demo does not connect to actual personal data, it cannot make real predictions
- It simply shows example outcomes, not any real forecasting
What algorithms does Life2Vec use?
Life2Vec uses the following techniques:
- word2vec algorithm to embed discrete events into continuous vectors
- LSTM and RNNs to model sequential event data
- Sequence-to-sequence architectures for mapping life event sequences to outcomes
How was Life2Vec trained? What hyper-parameters were used?
- Details on training methodology and hyper-parameters are in the published Nature Communications paper
- Key info like batch sizes, loss functions, model architectures, optimization approaches etc. are provided
- There is an extensive Supplementary Material with all these technical details
