Understanding broadcasting and arithmetic operations on different dimension tensors

Advertisements I’m currently working on computing various similarity metrics between vectors such as cosine similarity, euclidean distance, mahalanobis distance, etc. As I’m working with vectors that can be very large, I need compute time to be minimal. I’m struggling to understand how to work with vectors of different dimensions (they, do, however, share one dimension)… Read More Understanding broadcasting and arithmetic operations on different dimension tensors

How sklearn.metrics.r2_score works

Advertisements I tried to implement formula from Wikipedia but results are different. Why is it so? y_true = np.array([1, 1, 0]) y_pred = np.array([1, 0, 1]) r2 = r2_score(y_true, y_pred) print(r2) y_true_mean = statistics.mean(y_true) r2 = 1 – np.sum((y_true – y_pred) ** 2) / np.sum((y_true – y_true_mean) ** 2) print(r2) -1.9999999999999996 0.0 >Solution : Not… Read More How sklearn.metrics.r2_score works

Deep learning CNN: low accuracy

Advertisements I am training a convolutional neural network for binary time series classification. The training accuracy on both models is very different. If on the first it grows, then on the second it is always about 40%. There were also strong "jumps". Change filters=32/64/128 and epochs didn’t give the best results(kernel_size = 8). self.model =… Read More Deep learning CNN: low accuracy

Split Python list field into two and leave them in place

Advertisements How would you split a field in Python and then leave the two fields side by side in the list? Is there a command to use asides from .split()? Or would it make more sense to write a function that does this? How would it be done across multiple lists Performance is not a… Read More Split Python list field into two and leave them in place
