### What is the best way to train a text-based regressor model?

I want to build a deep learning model that can predict a continuous value (LogP in this case) given text inputs (SMILES notations in this case), the dataset is as illustrated below. SMILES notations ...

### Best way to measure regression accuracy?

I'm asking because classification problems have very concrete metrics like accuracy that are totally transparent to understand. Whereas regression models seem to have a very large number of possible ...

### Training and sampling for static model in multivariate time series

Let's suppose I have two time series $x_t$ and $y_t$. I also assume there is an underlying static model of the form: $$y_t=f(x_t) + \epsilon_t$$ As I said I consider the model a static model meaning ...

### How to pass multiple vectors and numeric features as input to the neural network?

I need help in a regression scenario. I have 12 input features. 4 of which are coordinates (each is a vector) in XYZ plane ...

### Are ranking models considered discriminative?

I'm developing a model that ranks entries based on cosine similarity to a query. Since it doesn't actually define a boundary between x and y I initially believed that such ranking models are not ...

### Feature selection by Simple regression vs finite impulse response (FIR) method (on TIME Series analysis)

We are working on prediction one company production estimation and the main field of works is like stock market prediction(Time series analysis and process data). So I have some comment on using ...

### Regress values inside the bounding boxes to predict a value in Object Detection

I am currently working on an object detection task. I have a dataset of Grayscale and Depth Images. The annotation format is x1, y1, x2, y2, class, depth. I have calculated this depth (of each object/...

### Image regression - estimating sensors from images

I am trying to use images to predict the sensor data of a racing game. Being a bit of a newcomer I have multiple questions. All help/suggestion is appreciated. Dataset The dataset looks something like:...
