 The goal is to learn optimal values for $k_1,k_2$ and $\lambda$ using the training set, 
 such that an improved Top-1 identification accuracy can be found.
 This is done using a multi-direction search algorithm to estimate $k_{1_{opt}}$ and $k_{2_{opt}}$
-and an exhaustive search for $\lambda$ from $ \lambda = 0 $ (exclusively Jaccard distance) to $ \lambda = 1 $ (only original distance)
+and an exhaustive search for $\lambda$ from $\lambda = 0$ (exclusively Jaccard distance) to $\lambda = 1$ (only original distance)
 in steps of 0.1. The results obtained through this approach suggest: $k_{1_{opt}}=9, k_{2_{opt}}=3, 0.1\leq\lambda_{opt}\leq 0.3$.
 
 To verify optimisation of $k_{1_{opt}}$, $k_{2_{opt}}$ heat plots were performed heat on
